Does anybody know the output shaft rpm? Every single bike I have ever owned, I have went with a -1 front sprocket to get faster acceleration at the expense of top speed. However, with the 125, I notice slower acceleration and top speed. I have done extensive testing and noticed that the stock front sprocket (14t) has better acceleration (and obviously) top speed than a 13t. Maybe if I can figure out the output shaft rpm, I can do the math and figure out why this is? At some point I know you can get too small but I didn't think it would be 1 down from stock.
