Re: [ST] Sprocket

[JAU149@xxxxxxx]

Thanks for all the good sprocket info , guys. I think I will go with the OEM. Next question....My 02RS comes stock with a 19 tooth up front ( I Think ....I havent pulled the cover to check yet ). Should I be looking at an 18 or a 17 tooth to replace it ? 

Thanks,

John
