smaller sprocket

[Darsey]

does any of you guys know if there is any such thing as getting a smaller sprocket for the back wheel so that there could be more top end

[st2lemans]

Are you hitting the rev limiter in top gear?

If not, a smaller sprocket will only give you less top end.

ciao Darsey -

yes, smaller rear sprockets are available from most of the sprocket manufacturers (afm, renthal, ducati performance, etc...).

a presto,

A smaller *rear* sprocket will produce less top end? He was asking about rear sporckets not frt. I thought a smaller rear will allow for a higher top end speed through a numerically lower final drive ratio.

If the bike doesn't have the power to pull to the rev limiter with the
existing gearing, going to a smaller rear sprocket for more top speed will
not help... instead, you could run out of power even sooner with the
taller gearing reducing torque multiplication. That said, I believe the
Hyper _does_ have the torque to pull a one- or two-tooth smaller rear
sprocket to the redline (see the threads on top speed). And yes, these
sprockets are commonly available in less than the stock 42 teeth... DP
