[QUOTE="bmetcalf, post: 40627, member: 792"] Would a 54t sprocket help a twin on the track? That would give 106 mph at the same revs (5750) as 125 mph with a 46t sprocket. If 125 mph is drag-limited, a bigger sprocket could make for even better acceleration. Engine longevity would have to be considered, though. Is there a US class for Vincent twins? There wasn't one, except against much newer bikes a few years ago. [/QUOTE]
