I don't know about the YZF but the YFZ has a top speed of 74 mph according to Yamaha.
if it is a Yamaha wolverine 450 it will go 61mph
2099
70mph
Stock gearing out of crate approx 72 mph
With stock gearing it will be in the 88 - 92 mph range.
how do you know if your yamaha atv is a 400 or a 450
The KTM sx is fast but the yfz is the best for what I do, what kind of riding do you do?
YFZ 450 has 39hp
id say 450...
It has 26hp
They are on the top of your battery
