Best Answer: it depends on the model, and weight of the rider, but 13hp is the minium for freeways and is lucky to do 60 mph. there are race versions that will do 90 mph :).eport Abuse. To a degree the gearing will determine how fast it can go. Increasing the size of the front sprocket or decreasing the size of the rear will increase speed. However that will decrease the the acceleration and will take longer to reach top speed.

Best Answer: Not fast at all. My son rides one and He is 6. I have a ATV Blaster and its 250cc and its fast. But if you really want something that's fast as hell then get a banshee. That thing moves. Its 350cc, Dual exhaust, dual carbs, 2 cycle/2 stroke, 6 speed and it has power band in every gear (all 2 cycles do).Power band is like pure power as soon as you give it gas.tart small and keep the small bike for a year and get used to riding. if u are a good rider and wana knoiw how fast they go then fined a straight away and f....ing pin it (you will know how fat it is at the end of the road). matt9923 · 8 years ago.
