Was just on Sprocket Specialists website looking for a bigger c/s sprocket for my R. Its been supermoto-ized (poser-only, not yet raced it ) and I am currently running 15/48 gearing. Have been considering going to a 16t cs to give me better highway gearing, as I always want to shift into 6th, except there ain't no 6th. It gets to the rev limiter pretty quick, which with 17" rims and tires gets me about 95 mph. Anyway, I went to Sprocket Specialists to pull the trigger on their 16t and noticed they are now also showing a 17t (!!??) Right now with my 15t, power in 1st is still "more than adequate". I figure a 17t will get me a very nice highway cruise, and a top-end of around 108 on the limiter (and I'll probably be tucking in at that point...). Yeah I know, "its not about top speed", but... for me it is. Question: I know some of you are running a 16t and you had to take off the front case guard to get the 16t to clear. Is anyone running a 17t c/s on their R? If so, did it clear the case without modification (other than removing the case guard)? Thanks.
