I dont want to disagree, but why do you always see drag bikes with a bigger diameter rim on the front then the back! Stability! Less Rpm on the Wheel gives less chance for bearing lockup, vibration, tread seperation, and larger turning radius...and several other things! This comes from a buddy who drag race the big bikes...this is what he told me! I dont doubt you can go fast on a smaller front...I would just prefer a larger fron wheel! Thats a bad ass bike though mmisterbungl!!!
