I have a 2012 f4 1000r. I went up 2 in the back from stock 41 to 43 while changing the chain and front sprocket also (kept stock at 15) and still with 525 but new did chain. However I'm thinking in dropping the front sprocket to a 14. I have a gearing calculator that gives me all the drive train ratio info but wanted to know if anyone has dropped down to a 14. My reasoning is quick acceleration in and out of traffic. I know these bikes pick up real well in the top end but let's face it your not hitting 165mph on the average streets. Any feedback would be appreciated.
