what do you mean there is no way to answer any part of the question? if you have two vehicles of given Cd, frontal area, weight, gearing, and hp, you should be able to make an educated guess at which will accelerate faster to a given point, correct? i guess the rider has too much effect on the Cd of the bike/rider combo? if i remember correctly the kz1300's were big 6 cylinder bikes that should have a hideous amount of drag. any chance on a stage5'ish tt walking one from a 120 punch? is it even worth the attempt? -Chris
