about 87 mph depending on the rider. i customized mine and decked it out and it clocked me at 110 mph with upgrades.
Depends of the landform, how it is built, or the weight. well it really depends on the 4 wheller not just the built or the weight of the wheller
about 150 mph
My 400ex is stock and it will run about 87 mph.there is no way they may go 65 but no way 87 your crazy
