Any of you race guys know what size sprockets I need to increase my top end? I'm going with a 1475cc motor so I'm not too worried about losing torque as I'll still have plenty. I just purchased a kit with a 23 front and 54 rear and those seem to be huge? I'm not building a track bike, but would still like to have usable power without my front end flying up everytime i think about twisting the throttle.

Smaller driven sprocket will lower your gear ratio, raising your top end,to find out what the ratio will be, just divide, 54/23=2.347
52/23=2.260
50/23=2.173
so the 23front and 54 rear will increase top end a tad.
not an appreciable amount, it was probly as close to stock as they could get with the chain and sprocket, most chain raio changers move a minimum of 2 teeth, as in my example math
interesting, so I would need to drop to a 48-50tooth in the rear to have a drastic increase in top end. Thanks, I just learned something today.
I wouldn't jump that far, you are looking at making 1st gear pretty tall, unless you have some one give you a push off at every redlight/stop sign
tall means. . .?
lower ratio,taller top end, a 48 tooth rear sprocket would probly stretch 1st out to 50 mph, but not able to pull away from stop with out burning the clutch up
so i would have to give it more revs to launch?
