loco you dont even have a top speed number on your bike, ive asked u before. im running 14,39 gearing(i think) with 20inc tires and straight cut gears with a one tooth difference. i hit 108mph on a ashphalt straight away. my bike isnt setup for top speed(i use paul turners and maxxis tires). will i ever hit 108 anywhere other than my street? no? could i do it again and tape it? well wait till the snows gone and ill bust out the radar gun. btw once u hit 90mph your helmet begins to french kiss you, at 100mph you begin to tear up.
