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?
The 07-08 R1 is perfect with the -1+2 setup. Gives the bike it's low end snap you are looking for without going extreme.See I'm rarely on the highway once in awhile just looking to.make the bike a little more snappy!
