So as you can see if you want acceleration, the 2.46:1 is for you, and the same as the stock sprocket setup the America's have from the factory. The 2.36:1 ratio setup would lower your RPM's and give you a higher top end. Not quite to the extent of an 18 tooth sprocket, but close. $850 is the rate for either.
