I wanna switch sprockets on my CBR6RR, but I don't know which is better, 520 or 525 pitch. I asked Phil at Moto-Heaven and he told me to get a 520. But all my friends say 520's are **** and what-not. What kinda pitch do you run? Thanks in advance.

 

520's wear faster unless your racing you dont need one.. go with a 525 or a 530 which is stock they last a long time ..
