Sprocket

What's the best sprocket ratio other then stock for highwAy cruising. I like to go out and cruise around 90 on the open highway. Not to worried about bottem end because my engine is strong.

Going to a smaller rear sprocket {less teeth} will give lower revs for any given speed {raising the final drive gearing}, its the exact opposite at the front, a larger sprocket {more teeth} raises the final drive ratio. Don't over do it either way. There are a number of gearing calculators online that can help you out...

What bike is it? For just HWY riding I use 16/35 with my 630 O ring chain. 15/35 for low speed and HWY. Better off the line but tach's a little high at 90.

In addition to the model, what sprockets are currently on the bike. A larger Fr sprocket or smaller Rr lowers the rpms. A larger Fr should also extend the life on the chain. Depending upon the model & what's on there now, a larger Fr may not fit, though.
