Hey there all... I have a 2007 600RR and I am looking at doing some work on the gearing. Have some mixed advise. Some people say upgrade the rear sprocket and others say the front. It is a 16/41 configuration at the moment. I was looking at either going to 15 on the front, or 44 on the rear. Can people shed some light on the pros and cons of each? What happens if I do both? Say 15/42 or 15/43? Thanks in advance.
