Dunno, but just had a look on the TTS site & they do a 1900 Haybusa for which they give 150ftlb & 245+bhp at back wheel for drag, hillclimb & sprint (bikes primarily I assume):

Mind you it is 14 grand, i.e. more than you could have bought last year's BSC 2-litre class winner for. BTW I think that has a 270bhp n/a Cosworth in it + more torque + more weight primarily in the box.
The thing that makes the big bike engine look really sad is, of course, the Honda S2000 engine, which produces almost the same power in showroom spec with a catalytic convertor, would do a fair few miles without a rebuild & could be picked up from a scrapper for not a lot. That is what I shall dream about tonight
