[QUOTE="David Trustrum, post: 146749, member: 21529"] Kawasaki used to (still?) measure their roadbike (& presumably dirtbikes) hp by reading rear wheel hp then removing the top end & rod driving the engine up to speed with an electric motor to calculate loses, add that onto the original run & claim that as crank hp. The logical progression is to measure fuel consumption, assume no losses & claim the calorific value of this. 100 hp 125 no wurries! Mid 30s for a 125 is pretty good. But what is the potential? Well RS125 Road racers were originally derived from CRs. The early ones wheezed out 30hp 10ish yrs ago. Now they are seeing mid 40s on proper gas & setup & some top level tuners are now expecting to graze 50 but these are like works level. ‘course before you salivate too much the development paths separated a while back but more importantly one of these engines in the dirt would be unrideable, even for factory riders unless you removed the dirt, the corners, the need for acceleration. . .
