I have the stock sprockets on my 929 and was wondering what would be the optimum sprocket tooth change for both front and rear sprockets? I noticed on a trackday someone had the same bike as mine with similar mods. In the front straight at T-Hill, I noticed the other 929 started pulling away from me. The guy told me that he changed the oem sprockets on his bike for ones that with had a different number of teeth and that may have something to do with it. He said that since he does not have any need to take his bike all the way to 175 or more, it just made sense to him to lower top speed for more grunt. Any suggestions?
