a stock Honda crf 450 goes around 150-170 nph depending on weight of the rider and the sprocket thats on it
depends on gearing
my stock crf 150 does 112mph.
On Thumpertalk, according to 4 different owners of stock to slightly modified CRF450s they all posted mid to upper 80s for a top speed.
Dont get me wrong they are both great bikes but suzuki has always had fast bikes my friend has a suzuki drz 125 and his friend has a Honda crf 150 the suzuki drz 125 has more power and is a great bike the Honda crf 150 is also a great bike but suzuki rmz 450 vs Honda crf 450 im going with......... suzuki rmz 450 all the way!!!!!!!
