How fast can a stock Honda CRF450R go?

A stock Honda crf450r will hit about 90-95 mph.But it all depends on the weight of the rider and what your tooth ratio is on your sprocket's? If you have a small sprocket on the front and a big sprocket on the back you are going to get more top end speed than acceleration .if it is the opposite way around you are going to get more acceleration but less top end speed.
