there is no way in hell dude.! you probably have one and lost to a Banshee and now you walk around wishing your quad would do 121mph.. get a life!!!!About 73 mph.
I have been 77mph on mine
My 2007 450R with HRC kit will run around 85mph
it will go from 75 to 80 stock.
If you are talking about a klx 450r, then the answer is 96 mph.
