MarkCR750:
Rob, I asked Sam to treat the bike gently on the Dyno, I wasn’t interested in how much power it was making just was the fuelling safe, he took it up to 7750 revs, max power was 54bhp if I remember correctly, he said it would have made more with a less restrictive silencer but who knows, I figured that Honda would have been lying about the original claimed 67bhp and it would have been measured at the crank, so in reality CB750’s probably make just over 60bhp at the crank, add in a few bhp to my results to compensate for it being measured as RWHP and it wasn’t far off what it should have been making.

robvangulik:
That is not bad at all, I've seen lots having about 50 hp at the wheel, so taken into consideration that chain and gearbox will consume their fair share of power 54 is a nice number.
