My 954 which is a wheelie machine with its short wheel base and fat tires 200 rear end but i had to stop those wheelies with a small sprocket in the front. I couldnt keep up with my friends because everytime we took off at high speed between 120 and 140mph the front would lift up and by the time i got control everyone was gone. oh yea and another thing i like is the 2 finger CRG brake lever and the scotts damper is a Must have.
