[QUOTE="Howard, post: 12307, member: 271"] Tom I think you must be the same generation as me, what you write is what I always understood to be the case. BUT By your (our) calcs 98 bhp should be good enough for 165 mph (unfaired) and the 125 Fireblade horses should take it to 185+mph. I'm sure things like rolling resistance change with speed, but 27 lost bhp seems a lot to account for - not including the fairing, and about 80 lbs less weight. Is this what I've suspected, Vincents work on horses big enough to carry Knights into battle, but the Japanese industry use racehorses. Phelps Oh well, I suppose in top gear, we'd only lose about 5% on the way to the rear wheel. As an aside, the biggest gearbox we built would transmit 500,000 Nm and was used to turn a swing bridge. Our fitter was big on attention to detail, and liked to despatch all his drive units with the keyway on the output shaft vertical (at 12 o'clock) - he went for a coffee break while it was turning into position, when he got back the keyway had turned too far, so he watched it for an hour to make sure it didn't overrun next time. He said it was because he had pride in his work, but I have my suspicions. H [/QUOTE]
