WORLD SUPERBIKE TECHNOLGY
The Kawasaki Ninja ZX-10R ABS motorcycle has dominated the World Superbike Championship for many years – finishing second in 2012, first in 2013, second in 2014, and recently clinching first place in both the 2015 Riders’ Championship, as well as the 2015 Manufacturers’ Championship title by a healthy margin over its nearest rivals.

All this success has a direct impact on Kawasaki’s street products, with the technology being fed back to Kawasaki Heavy Industries, Ltd. for integration into the 2016 Ninja ZX-10R ABS motorcycle. This has helped to sharpen the motorcycle’s edge, resulting in better handling, improved lap times and a thrilling riding experience.

Participating in the most competitive arena in the world for production motorcycles, Kawasaki continually pushes its technology forward, not only in terms of engine performance but also handling and the suite of electronic rider aids thanks to the introduction of a ground-breaking Bosch five-axis Inertial Measurement Unit (IMU) and Kawasaki proprietary software. Much of this technology is transferred from the World Superbike pit box to the 2016 Ninja ZX-10R ABS motorcycle.

ENGINE
For the 2016 model year, the architecture of the proven 998cc engine retains its 16-valve, DOHC, inline four-cylinder layout and its over-square 76 x 55mm bore and stroke dimensions. Known for its strong mid-range power delivery and ballistic top-end performance, Kawasaki has made a large number of improvements to continue its winning advantage by improving peak power output as well as the power delivery. Almost all of these are the direct result of Kawasaki racing development, which translates to the 2016 Ninja ZX-10R ABS, creating a very competitive motorcycle.

These improvements start with a lighter crankshaft, which allows quicker revving for improved throttle response and acceleration. It also has increased low- and mid-range power output, which is appreciated when exiting a corner on the racetrack or on a favorite stretch of blacktop. Another advantage of the reduced reciprocating mass is better cornering turn-in and side-to-side transitions.

The crankshaft also has a new balancer, which is lighter and damps vibrations just as effectively. The crankshaft’s connecting rod journals have a new coating for reduced friction at high RPM.

The cylinder head has revised intake and exhaust ports. These have a straighter cross-section to allow better gas flow, contributing to the increased power output. Only the intake ports were polished on previous models, but the 2016 model also has polished exhaust ports to further increase power.

The cylinder head design incorporates larger coolant passageways to help provide engine reliability. Long-reach spark plugs are another part of the package, helping to boost ignition efficiency.

The combustion chamber shape is revised and the titanium exhaust valves are increased 1mm in diameter to 25.5mm, boosting high-RPM power output, while the combustion chamber shape is revised for the same goal.

Both the intake and exhaust camshaft profiles offer greater overlap to increase power at high RPM, without adversely affecting exhaust emissions. A new camshaft chain tensioner is also specified in order to help provide accurate valve timing and to reduce mechanical noise.

The all-new pistons are cast from heat-resistant alloy that improves durability, while overall weight is reduced by 5g per piston thanks to shorter skirts (37.7mm instead of 39.2mm). This superior construction and reduced mass means they are able to cope with the greater demands of the more powerful engine as well as improve engine response. Furthermore, a dry-film lubricant coating on the piston skirts reduces friction at low RPM and helps with the breaking-in process.

Kawasaki engineers also took the opportunity to increase the cylinder wall thickness in order to produce a more rigid engine block, contributing to the overall reliability.

The 2016 Ninja ZX-10R ABS motorcycle has 25% larger air box volume and is fitted with a new air filter element that offers 60% more surface area and greater air flow. This upgrade contributes to better engine responsiveness, improved corner exit acceleration and better low- to mid-range power.

New electronic throttle valves allow precise control of the intake airflow, contributing to efficient power delivery and seamless integration of the electronic aids such as the S-KTRC Traction Control, the new KLCM Launch Control and KEBC Kawasaki Engine Braking Control.

The new throttle bodies necessitated the use of a new Engine Control Unit, which is mounted under the seat in an aluminum case to provide heat dissipation.

The titanium-alloy exhaust system, which helps with weight reduction and mass centralization as well as the power to weight ratio by removing significant weight from the bike.

New titanium-alloy headers use a special heat-resistant alloy, which is unique to Kawasaki in a motorcycle application and have a new connector pipe joining headers three and four to help smooth the engine response. The heat handling capacity contributes to durability, while the new alloy also allows thinner pipes thickness, reducing weight even more. The titanium alloy exhaust silencer offers nearly a 50% larger volume than the previous model, reducing sound levels and overall weight.

TRANSMISSION
Another feature directly derived from the racing success of the Ninja ZX-10R ABS motorcycle is its cassette-type, close-ratio transmission. The gear ratios are idealized for circuit riding. Shorter ratios for second through sixth gear deliver strong corner exit acceleration. The closer ratios also give stable downshifts and works with a slipper clutch. The clutch is 130g lighter than in the 2015 model, thanks to a thinner primary gear.

A new dry-film lubricant coating has been applied to certain gears in order to reduce internal friction, improving shifting speed.

A brand-new feature for 2016 is the standard Kawasaki Quick Shifter (KQS). Working on upshifts only, it uses the same contactless sensor as the Ninja H2R motorcycle and helps to provide seamless acceleration thanks to rapid upshifts, which is especially beneficial for circuit riding.

KAWASAKI ELECTRONICS SYSTEMS
The 2016 Ninja ZX-10R ABS motorcycle uses a full complement of electronics that allow the rider to fully explore its performance on the track. The Kawasaki electronic system uses a proprietary algorithm that optimizes the electronic stability systems. The Kawasaki system uses a Bosch five-axis Inertial Measurement Unit (IMU) with software developed in-house, drawing on the experience of the Kawasaki Race Team’s World Superbike experience, making this application unique. For example, it takes the pitch and roll rate data measured by the IMU, and the ECU calculates the yaw rate, resulting in six-axis operation. It provides an additional layer of precision to the already high-level electronics package, giving the rider greater confidence on the track by allowing them to explore limits within the parameters controlled by the on-board computer.
Specifically, the IMU is able to measure longitudinal acceleration and braking, transverse or lateral forces when cornering, vertical acceleration such as when cresting a hill at steady speed, rotational roll rate (or lean angle) as well as the pitch rate such as during a wheelie or under hard braking. The Kawasaki software adds the sixth axis with yaw rate calculations, such as experienced during a powerslide where the rear wheel is out of line with the front.

The IMU input into the ECU works in conjunction with wheel speed, brake pressure, throttle position, engine RPM and throttle opening sensors. This high level of chassis orientation awareness means the ECU can adapt to changes in tires and even road camber. This gives the Kawasaki system an advantage because the S-KTRC Traction Control, KLCM Launch Control, KIBS Intelligent ABS and Cornering Management Function can respond to real-world conditions in real time, rather than relying solely on pre-set limits like some competitor’s systems.

S-KTRC KAWASAKI TRACTION CONTROL
The Sport-Kawasaki TRaction Control system now has five modes of intervention, compared to the three settings on the previous model. Modes one and two are designed for a racer on the track. Mode three is designed for a dry circuit with high-grip tires. Mode four is intended for dry canyon roads or commuting, while mode five is programmed to suit wet circuit or street use.

The inclusion of the IMU means that S-KTRC changes from being a purely predictive system to one that also offers feedback. The new predictive/feedback system offers even more precise management to help riders push harder on the racetrack by maximizing acceleration.

The highly sophisticated traction control system is based on racing technology and acknowledges that in order to accomplish the quickest acceleration, a certain amount of tire slip is required. In order to optimize traction, S-KTRC varies slip according to the prevailing conditions, taking information from a number of parameters to get a real-time image of what is happening. As such, it looks at front and rear wheel speed (slippage), engine RPM, throttle position, acceleration, etc. The system also looks at the chassis’ orientation relative to the track surface, rather than simply in the horizontal plane. Therefore, it is able to account for camber, gradient, etc. and adjust accordingly. It is also able to adjust for tire wear, tire profile, tire compound and numerous other factors.

Acting before the slippage surpasses the limit of adhesion, the ECU is able to minimize engine power reductions, resulting in ultra-smooth operation and maximum forward acceleration on the track.

KIBS KAWASAKI INTELLIGENT BRAKING SYSTEM
The Kawasaki Intelligent Braking System is available on the Ninja ZX-10R models equipped with the optional ABS braking. The multi-sensing brake management system uses high-precision control to modulate brake pressure during sport riding.

CORNERING MANAGEMENT FUNCTION
Using the five-axis IMU and Kawasaki’s original chassis attitude software, the Cornering Management Function helps distribute optimum hydraulic pressure to the calipers based on the motorcycle’s lean/pitch angle. The result is reduction of the motorcycle’s tendency to stand up when applying the brakes in a turn on the track. Instead, the Ninja ZX-10R ABS motorcycle is better able to follow the rider’s intended line while slowing down for a difficult turn, rather than having the tendency to run wide.

KLCM KAWASAKI LAUNCH CONTROL MODE
Another new addition to the 2016 Ninja ZX-10R ABS is the Kawasaki Launch Control Mode. It has three modes, which vary the level of intrusion via the ignition and intake air (throttle valves).

The three different modes are designed to suit different rider abilities. Mode one offers less intrusion from the system but requires the rider to operate the clutch and throttle with greater sensitivity. Mode three allows the electronics to do more of the work while the rider simply drops the clutch with the throttle wide open. Mode two gives a setting between the first and third.

The Kawasaki Launch Control assists racers by optimizing acceleration from a stop by controlling engine output to prevent wheelspin and minimize font-end lift when leaving the starting line.

Using an indicator on the digital instrument display, the rider selects KLCM with the Power Mode also on FULL.

KAWASAKI ENGINE BRAKING CONTROL
The Kawasaki Engine Braking Control was first seen on the Ninja H2R motorcycle and enables the engine braking to be managed when the rider snaps the throttle shut. This feature is intended for circuit use only and contributes to smoother braking and corner entry when in operation.

POWER MODES
Selectable Power Modes have been available on the Ninja ZX-10R motorcycle for several years but this new system now has three modes to allow the rider to select the power delivery to suit the prevailing conditions.
The available levels are Full, Middle (80%) or Low (60%). These reduce power by the stated amount and are easily selected via the rocker switch on the left handlebar, allowing riders to select the power delivery to suit their preference.

CHASSIS
On the frame, the steering head pipe is moved 7.5mm closer to the rider than the previous model, placing more weight on the front-end, resulting in improved front-end feel. This helps to improve the motorcycle’s stability on corner entry. It will also help in transitions, when flicking the bike from one side to the other, creating nimble handing and increased corner speed.

The front section of the main frame has been internally profiled to reduce induction noise, effectively using the interior as a resonator chamber. This has the effect of allowing the exhaust to be liberated, freeing significant horsepower from the engine while still meeting US noise regulations.

The swingarm is lengthened 15.8mm, resulting in a wheelbase of 56.7”, which is almost 0.5” longer than the previous model. The swingarm is also torsionally more rigid thanks to additional bracing. This contributes to the motorcycle’s nimble handling and excellent behavior in corner entry as well as transitions.

SUSPENSION
Giving the 2016 Kawasaki Ninja ZX-10R ABS motorcycle a distinct advantage over its competition is the Showa Balance Free Fork (BFF). This is the first mass-production motorcycle application for the fork that was jointly developed with Showa in World Superbike competition.

The main feature of the Showa BFF is that the design of the hydraulic system eliminates the pressure balance fluctuations typically found in conventional forks. With the BFF, the damping valves are located in one place – outside the fork legs in the damping force chamber. This allows the entire surface of the fork pistons to push the hydraulic fluid toward the valves in the damping force chamber, with nitrogen gas in the compression chamber pushing back against the oil, helping to maintain the balanced pressure inside the fork tube.

Compression and rebound damping are generated (and adjusted) completely independently from one another by the compression and rebound adjuster screws on the damping force chamber at the bottom of each leg. Locating the adjustment in this single place has resulted in a more focused design that greatly improves responsiveness. Spring preload adjustment is located on the top of each fork leg.

Other advantages of this system include better traction, improved low-speed comfort and increased front-end feel. When combined with the benefits in braking, front-end feel and comfort, riders will truly appreciate this new fork on the racetrack.

The rear shock absorber is a Showa Balance Free Rear Cushion (BFRC) unit that also resulted from joint development in World Superbike competition. Just like the forks, the rear shock has a separate damping force chamber that houses the compression and rebound damping adjusters. By separating them, it again allows the entire damping piston to focus on hydraulic fluid movement. There is also external spring preload adjustment. The result is increased traction and superior shock absorption.

The horizontal back-link suspension has revised linkage ratios for 2016. This has allowed a wider range of adjustment, making it easier for the rider to feel the changes and causing the vehicle to be more targeted to circuit use than ever before.

BRAKES
As another direct consequence of Kawasaki’s World Superbike involvement, the 2016 Ninja ZX-10R motorcycle has been fitted with a Brembo front braking system. This not only includes the very high specification M50 aluminum monobloc four-piston front calipers (with 30mm opposed pistons), but also larger Brembo front rotors, up from 310mm last year, to 330mm. The rotors are cross-drilled and have a circumferential groove in the outer edge to aid heat dissipation.

The Brembo components offer strong initial bite for circuit use and great feel through the lever. Each part is inspected and adjusted by Brembo to eliminate and ineffective (idle) stroke, providing strong braking force from the initial lever stroke. As a further measure to help provide excellent brake action, race-quality stainless steel braided lines have been fitted front and rear to help ensure direct feel when the brakes are applied.
On the rear, the previous petal-shape disc is replaced by a similar-sized 220mm round rotor to match the front. The two-piston Nissin caliper used by last year’s model remains.

Riders who choose to purchase the 2016 Kawasaki Ninja ZX-10R ABS motorcycle will also experience the Kawasaki Intelligent anti-lock Braking System (KIBS) described earlier in this release. It uses high-precision control to regulate brake pressure during sports riding.

The 2016 Kawasaki Ninja ZX-10R ABS motorcycle also benefits from Cornering Management Function, which uses the five-axis IMU to allow riders on the track to brake into a turn, without the tendency for the bike to stand up and run wide.

WHEELS & TIRES
The wheels remain unchanged from the 2015 model year, although the brake rotor mounting areas are revised in order to increase the rotor stability. Angled air valves have also been fitted, identical to those used on the Ninja H2R and Ninja H2™ motorcycles, to make tire air pressure maintenance easier with the very large brake rotors that are fitted.

Another feature carried over from the Ninja H2 platform is the Bridgestone Battlax RS10 tires, which remain the same size as before: 120/70 ZR17 front and 190/55 ZR17 rear.

BODYWORK
More World Superbike-inspired development hits the street in the design of the front cowl. This time, it’s in the form of increased wind protection, thanks to a larger screen area, which allows the rider to change positions more easily thanks to reduced wind buffeting. The new cowl has also improved the aerodynamic efficiency, reducing the drag coefficient and aiding stability. The front windshield is also supported over its entire length by the cowl, reducing vibration over the previous model’s “floating” design.

Two small air intakes are strategically placed on either side of the windshield in order to help prevent a negative pressure area forming in the cockpit, reducing helmet buffeting and increasing comfort on longer journeys.

The headlights have been updated, receiving more compact lenses to match the new front cowl design and give the bike a more menacing demeanor. The mirrors are similar to the previous model but the stays have been lowered to integrate with the new cowl design. The new front fender has a stepped design, which helps to direct airflow to the radiator and is very similar to the fender of the Ninja H2R motorcycle.

In the rear, the new cowl is wider than before to create a better visual balance with the front styling. The new passenger seat is sportier and matches the design of the sharper new LED tail light, which now has separate turn signals. The license plate holder is also new and the modular design is easily removable for track use.

COCKPIT & CONTROLS
The main instruments on the 2016 Ninja ZX-10R ABS motorcycle have been retained from last year, but the LCD portion is new and includes the option to change the background color from black to white. There is also an IMU indicator, as well as Launch Control, Quick Shift and Engine Braking activation, plus gear position indicator, Power Modes, S-KTRC mode (and Off), low fuel level, Economic Riding Indicator, intake air temperature, odometer, dual trip meters, average fuel consumption, instant fuel consumption and a host of indicator lamps.

To select these new functions, a rocker switch is located on the left handlebar that incorporates a “select” button to allow the rider to scroll through the functions.

There are new bar end weights, which have a more detailed design.

Other updates include revised settings for the Öhlins electronic steering damper to suit the new chassis setup. It is the same damper as used on previous models, which alters its damping characteristics according to speed and the degree of either acceleration or braking. The settings were chosen so at low speeds the damper does not interfere with the intrinsic lightweight handling, whereas at higher speeds, the damping increases to help enhance stability.

With the handlebar moved 7.5mm closer to the rider, thanks to the repositioned head pipe, the riding position is more compact than before. This allows riders more flexibility in choosing their position on the motorcycle.
In preparation for the addition of an aftermarket data logger by amateur and professional race teams, a CAN coupler is provided inside the cowl.

NINJA ZX-10R MODELS
There are four model variations available from Kawasaki’s nationwide dealer network. The Ninja ZX-10R motorcycle and its ABS-equipped version, the Ninja ZX-10R ABS motorcycle, are both available in the new Metallic Matte Carbon Grey.

2016 KAWASAKI KX450F



Kawasaki says:

The new Kawasaki KX450F packs more power, better handling and less weight to provide the quickest path to the race podium

Forty years of Kawasaki KX™ racing tradition, innovation and championship pedigree can be summarized in one word: Proof. Whether it’s claiming 32 AMA Supercross titles, a plethora of wins in media shootouts, or the bike ridden by legends such as Ryan Villopoto, Jeremy McGrath, Jeff Emig, Jeff Ward and Ricky Carmichael – riding a KX motorcycle is the quickest path to a podium. The proof? It’s verifiably the most successful supercross and motocross bike from any manufacturer.

As the flagship of the KX fleet, the Kawasaki KX™450F motorcycle is the most successful 450cc motocross bike available on the market today. This powerful, agile and technologically advanced machine is built for today and tomorrow’s champions. More than simply race-ready, the KX450F motorcycle is like having factory support at your fingertips. It is the most advanced motocross bike Kawasaki has ever produced and is backed by the industry-leading Team Green™ support network that can be found trackside, with plenty of suspension advice and even engine settings.

The KX450F motorcycle is completely new for 2016, to give riders the sort of advantage the competition might consider unfair.

Kawasaki is not sitting on its laurels, giving the engine more power and 7.5 lb less weight than before. In fact, the entire motorcycle has seen a significant weight reduction thanks to the redesigned engine as well as a new aluminum perimeter frame.

Riders will also enjoy the improved rider adjustability as well as electronic upgrades aimed at maximizing performance for a variety of riders in any situation while giving the rider supreme confidence.

ENGINE
Kawasaki’s already powerful flagship motocross bike is even stronger for 2016, with the KX450F motorcycle boasting a more powerful and lighter engine. The revisions are extensive and start with new engine cases to save weight while optimizing the design to increase strength and rigidity. The location of the oil scavenger pump was also changed, swapping from the left case to the right case.

The cylinder head updates include revisions to the intake ports, which are less curved than before, improving mid-high RPM performance and over-rev. The intake port cores are also given a special coating during the head casting process to make the ports smoother. The extremely smooth surfaces and revised port shape increase the intake efficiency and performance at
all RPM.

The 36mm titanium intake valves have a revised head area. The new design, with slimmer throat angle and reduced recess (similar to valves on Kawasaki supersport engines) contributes to increased high-RPM performance. Revised intake cam timing (advanced 2-degrees) contributes to better low-RPM performance, while the camshaft is 0.5oz lighter than before. A new intake camshaft sprocket is 0.7oz lighter.

The single cylinder is offset (8.5mm forward) to reduce mechanical loss through friction from the piston movement, enabling more efficient power generation. This necessitated a revised crankshaft shape, corresponding to the revised crankshaft housing. The crankshaft balancer shape was also changed – reducing its size and lightening it by 1.9oz. Further updates were made to the crankshaft balancer drive gear and driven gear, resulting in a combined reduction of 1.4oz.

A new crown design for the Bridged-Box bottom piston is based on the AMA factory race bikes and matches the new intake valve shape as well as contributing to the 12.8:1 compression ratio.

Another addition for 2016 is the redesigned air box, which does away with any steel parts, resulting in a weight savings of 8.8oz. It also utilizes new underseat intakes at the back of the seat. These and the revise shape of the air box help to ensure clean airflow, improving engine response and reducing intake sound to meet local market requirements.

Changes were made to the throttle to reduce vibration. This resulted in a new compact fuel injector being used. The outer part of the fuel pump was also revised, changing the flange position in order to lower the fuel tank position, contributing to the motorcycle’s overall lower center of gravity.

Further upgrades include a new exhaust system. It starts with a new header design that features a resonator to improve low RPM power and help reduce the sound level.

The result of these changes to the powerplant mean increased power. And when combined with a lighter overall curb weight, the 2016 Kawasaki KX450F motorcycle has an improved power-to-weight ratio that provides improved acceleration response.

Another weight saving measure saw 9.2oz trimmed from the transmission gears and shafts, which retain their overall strength while contributing to the motorcycle’s dynamic performance. Finally, the shape of the kickstarter has altered, resulting in a saving of 2.6oz.

ELECTRONICS
With all these engine changes, the revolutionary and popular DFI® couplers are again available for the Digital Fuel Injection system. Three are supplied with each motorcycle and allow the riders to quickly change the fuel injection mapping to suit any riding condition. The four-pin DFI couplers are designed for standard, hard or soft terrain settings. The rider simply connects the appropriate coupler cap to suit the track conditions and the DFI couplers immediately activate an ignition mode to match.

The KX450F motorcycle’s Launch Control System is another popular feature that helps obtain holeshot supremacy for the amateur and pro rider alike. The push-button activation retards ignition timing in first and second gears, helping to maximize traction off the line. Once the rider shifts into third, normal ignition mapping is resumed and full power returns.

As a further benefit of owning a KX450F motorcycle, the engine ECU remains fully programmable thanks to the new handheld Kawasaki Accessory KX FI Calibration Kit. This portable device allows custom maps to be created giving riders precise adjustment of fuel and ignition settings. This new handheld module eliminates the need for a trackside laptop computer. It can store up to seven preset maps and is PC-compatible.

CHASSIS
Kawasaki’s engineers worked tirelessly to improve handling and chassis feedback with a new aluminum perimeter frame. The perimeter spars are 6mm slimmer than the previous frame, allowing easier rider movement. It is also lighter by 1 lb, while the subframe (seat rails) has thicker walls for increased strength. Overall rigidity has been improved with a new swingarm (while losing 7.8oz in the process), helping rear-wheel traction and rider feel.

The alloy swingarm has a cast front section and twin tapered hydro-formed spars in a raw aluminum finish. Forged chain adjusters are also fitted with a self-locking rear axle nut. The axle nut holds the 80 lb-ft torque setting without the need of a cotter pin for ease of maintenance at the track.

The original goal was to create the lightest motorcycle in its class, increasing the bike’s agility and helping to reduce rider fatigue, making the KX450F more potent than ever before. Following extensive engine and chassis revisions, the 2016 Kawasaki KX450F motorcycle has seen a significant 7.5 lb reduction in curb weight (including fluids), giving it a total weight of 239.6 lb.

Weight savings from the engine group (including intake and exhaust systems) amounted to approximately 4.4 lb, with savings from chassis components totalling approximately 3.1 lb. Some of the major contributing component weight savings include:
crankcases (left/right) – 13oz
transmission – 9.2oz
air filter – 8.8oz
frame – 14.1oz
suspension (front/rear) – 10.9oz
swingarm – 7.8oz

BODYWORK & SEAT
The 2016 KX450F motorcycle receives all-new bodywork with aggressive styling to suit its heightened performance. The minimalist bodywork is light and features angular styling for the new number plates, shrouds, fenders, skid plate and water pump guard. The new bodywork unifies the radiator shroud and side covers for a smoother, seamless rider interface that is 1.2” slimmer at the widest point, and allows unimpaired movement around the motorcycle. The radiator was reshaped in order to achieve this, creating a vee-shape and allowing the shrouds to be slimmer.

The top of the fuel tank is lower than before, allowing easier progression from the seat to the tank. The flatter design gives the rider greater freedom of movement when changing riding position, while also allowing the rider to sit further forward.

Aggressive styling for the new front fender adds to the motorcycle’s overall racy appearance and also saves 1.8oz in weight overall the previous model year.

The appearance is further highlighted by green engine plugs, oil cap and generator cover plugs, as well as green alumite suspension adjusters and black alumite wheels. Another neat detail is the embossing
on the clutch cover, which was designed to gradually appear as contact from the rider’s boots wears away the paint. A new generator cover has also been incorporated to fit the new crankcase.

To protect the 2016 Kawasaki KX450F motorcycle from general wear and tear encountered during a typical day at the track, a large synthetic skid plate offers great protection with minimum weight. The revised design has oval holes that facilitates easy mud removal and reduces the weight further.

SUSPENSION & BRAKES
With Kawasaki engineers creating a lighter motorcycle, its agility was increased, allowing the suspension and brakes to work more efficiently and effectively. This is especially true of its state-of-the-art Showa SFF-Air TAC (Separate Function front Fork, Triple Air Chamber) fork technology, which separates the damping and shock absorption duties into the individual fork legs. The left fork tube contains the damping assembly and the right fork tube contains the air spring. Instead of the steel coil springs found in conventional forks, the SFF-Air TAC’s right fork tube has three chambers filled with pressurized air that act as a “spring”. Eliminating the steel coil springs reduces friction by approximately 20% and creates an extremely smooth action throughout the fork’s stroke. This has the added benefit of greatly reducing weight and allowing a larger damper piston to be used, providing smoother action. New low-friction fork seals and revised valve settings for reduced damping deliver easier fork movement, matching the pitching characteristics to the lighter chassis.

This works-replica fork is derived from Kawasaki’s factory race bike. It is lightweight and rigid, contributing to superior riding stability and front-end feel. The low friction design contributes to an extremely smooth fork action, while precise settings are possible merely by changing air pressure.

The fork has traditional 22-position compression and 20-position rebound damping adjustment. Furthermore, the rider can adjust the internal air pressure with the Kawasaki Genuine Accessories 0-300psi Digital Air Pump that is supplied with the KX450F motorcycle. Changing the air pressure covers a range of settings offered by optional springs in a standard fork, including quick changes of ride height, without needing to disassemble the fork tubes. The pump’s digital display offers precise air pressure setting, and its casing stores the engine’s DFI couplers for the fuel injection system, allowing better organization on practice or race days.

New linkage ratios for the Kawasaki Uni-Trak® suspension system were designed to suit the new aluminum frame and swingarm. Mounting the link below the swingarm allows a longer rear suspension stroke, while maintaining a low seat height. Dual compression adjustability from the Showa shock allows high-speed and low-speed damping rates to be set separately. The shock reservoir has a friction-reducing internal Kashima Coat for improved suspension action. This race-oriented suspension offers class-leading action and adjustability on par with the Showa SFF-Air TAC fork. The fully adjustable unit allows for precise settings to help keep the rear wheel planted and the rider out front.

Riders looking for an extra edge over the competition can use the optional Kawasaki rear suspension tie rod. It is 1mm longer than stock and can be used to reduce seat height by 4mm to give the rider greater control and adjustment.

Being able to enter every corner at the desired speed is critical to fast lap times. The 2016 Kawasaki KX450F motorcycle uses an oversized 270mm, petal-shaped front brake rotor (largest in class) from the renowned manufacturer, Braking. It helps provide powerful stopping forces, good lever feel and consistency in all conditions. It is paired with a 240mm petal-shaped Braking rotor on the rear.


ADJUSTABILITY
Kawasaki’s commitment to the rider continues with an adjustable handlebar and footpegs to fit various sizes and riding styles. The footpegs feature dual-position mounting points, with a lower position, which reduces the height from the standard position by an additional 5mm. The lower position effectively lowers the center of gravity when standing, and reduces knee angle when seated.

The handlebars offer 4-way adjustable mounts. With 35mm of range, the multi-position handlebars feature two mounting holes, and the 180-degree offset clamps provide four individual settings to suit different size riders.

Equipped with a flat seat, adjustable footpegs and handlebar as well as fully adjustable suspension, the 2016 Kawasaki KX450F motorcycle can be tailored to suit a large range of riders. This perfectly complements the wide range of damping settings as well as the DFI couplers and optional handheld Kawasaki Accessory KX FI Calibration Kit, allowing the rider to find the ideal engine characteristics to suit a particular track or conditions. So while the base settings on the KX450F motorcycle are based on extensive testing, including racing, the motorcycle provides a huge range of technology and adjustment to help ensure every rider can fully exploit the incredible ability of this extremely capable motocross bike.
