What type of riding you do mostly do? If you do a lot of highway miles, a -1/+2 is going to substantially increase the rpm for a given cruising speed. Also, you'll be losing around 18 mph off your top speed.I have a 2007 r1 it has power commander, BMC filter, Coffmans shorty exaust, and a ecu flash. Just wondering what set up I should get?
Go to the Gearing Commander website, load your bike's stock data from the drop-down menu and play with different gear combinations to see what effect they will have.
