I would have front and rear tires checked for flat spots. Maybe from hard braking. Atleast have the dealer re-balance them, it should be under warranty!

Pull Hard on the bars and pull your body on the gas tank and see if you load the front end
and the wobble stops. I am sure you checked to see if rear in aligned with the swing arm marks.
Pinch bolts tight etc on front forks. Is this the first time you have done this at that speeed?

If you have a mag base and a dial indicator you can check the front tire run out. A way to check
for a flat spot with tire still on bike. Also check the rim run out too. Hurricane has a good idea, check front tire and rebalance..I run Michelin Pilot Road 2CT never had this happen to me. I have had the 14
shake the bars in 2nd gear at 8000 RPM. Front end was wanting to lift up :-) pulled foward and nutted up on tank and it smooths out. So I start out leaning Foward when I do this :-)

+1 and I'm not extended either but it happens while racing without a damper at full throttle.

Hey guys what to you think about the stock suspension setting... mine was shit... im a 200 lbs and did some adjutment and now its gone ... the sag is not right at all for a 150 plus driver the stock setting is for a avrage 150 lbs smal asian guy we north americain have more sholder and the weigt is not balance right so i did mine and it make a big difference its all about tranfer i think

the stock suspension is too soft no matter what you set it at on the 14
