depends on gearing
a stock honda crf 450 goes around 150-170 nph depending on weight of the rider and the sprocket thats on it
my stock crf 150 does 112mph.
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!!!!!!!
