You wont increase the power output of the engine by changing the sprockets but could reduce losses in the drive train therefore increasing the power at the wheel. The percentage lost in the chain etc is minimal though and certainly not 20HP.
you sacrifice top end for acceleration or vice versa Lots of ZX12 owners used to put an extra tooth front sprocket on that give more low down acceleration but meant the bike would now top out at around 170 mph
Well no, you wouldn't necessarily alter the drivetrain loss to an appreciable level, but it does makes sense that you gain or lose WHP (Wheel Horsepower) due to the difference in torque multiplication through the final drive ratio - at least that's what it appears to show I believeThough thinking about it, I guess you are more just moving the power band around at the rear wheel? Bare with me whilst I run this through my head... and write it all down :PAcceleration can be altered by adjusting the final drive ratio. This seems sensible enough to me.As Acceleration is a function of power (force) there must be a difference in power to obtain a difference in acceleration.Therefore changing the sprockets (which we know alters the acceleration) must alter the available power at the rear wheel
Any chance you could talk to my mrs about this? I'd call it payback for all those years of asking "so how was your day love"
