i have a 2002 954rr and at 60 MPH(96 KPM) and im turning 3,800-4,000 RPM's. Is that good? i have 16 tooth front and 43 tooth rear sprockets.

 

That is the stock sprocket setup for the United States. I think they had 16/42 in Europe.

I am running 16/43 (2.6875:1) Right now and at 75 MPH the tach indicates 5000 RPM.

I have a 15 tooth front sprocket in my toolbox. I am waiting to get a speedo DRD to correct the speed reading when I install the 15/43 (2.8666:1) combo.

That 15 tooth front will raise the RPM's a few hundred (6.6% higher) at freeway speeds, but should provide a little more acceleration, for even more fun.

 

i kinda wanna do a 17 tooth front and a 40 tooth rear do u think that is a good idea on my engine and transmission behalf

 

No. I think you will wear out your clutch with that tall gear and the bike would be SLOW to accelerate.

 

i would agree, i would keep close to stock, try a just going a tooth if your looking for mileage, down in front, up in rear will give better accel, vise versa will give more top end, but i wouldnt go to tall and get the rpms to low

 

What are you wanting the bike to do?
