Does anyone know the size of the rear sprocket on the 450r from factory? Also, are there any aftermarket companies out there making larger one yet?

Thanks,
Ryan

 

I think i herd it was 38 teeth

 

I went out to the garage and counted them for you. 38 teeth. Looks like standard Honda bolt pattern, same as 400EX, 300EX, 250R, etc.
Everybody makes aftermarket stuff for this. Try White Bros., Rocky Mountain, etc.

 

Thanks!
