Here's an odd idea... of course my saying it here will accomplish nothing, and for that matter quite likely anyone (but the President of Honda) saying it anywhere would accomplish nothing... but perhaps a far better and novel route to the supposed horsepower problem would be this:
Require a given MINIMUM (!!!) torque at some modest rpm, like 5000 rpm let's say. And rule out variable cam schemes, which aren't presently being used anyway.
(A better though more sophisticated method would be to require a given minimum area under the curve within a given range in the lower midrange... for example averaging so-many ft lb between 4500 and 5500 rpm, so there would not be an issue of tuning to create a spike at exactly a given test point.)
If the engine has to turn say 80 or whatever ft-lb at the crank at 5000 rpm, or average that between say 4500 and 5500 rpm, then that is going to -- in a much more subtle, nicer, and less-costly way than restrictor plates or displacement decrease -- limit the maximum hp that can be obtained while also making for a more tractable and overall better racebike.
Instead of a peakier nastier one as the smaller displacement rule will do.
I haven't had time to think that through, just thought of it now, but it seems appealing to approach it by requiring a minimum of a good thing, in other words demanding some quality be improved or at least held to current standards, rather than arbitrarily capping some other good thing below what the engineers could otherwise achieve or employing some limiter like restrictor plates. (Which, as a fan, I'd still prefer over the displacement decrease -- but Honda would not.)
