Over 140 MPH although I've never tried to push it all the way. I'm sure it would do 150 MPH.
fast
if it is a Yamaha wolverine 450 it will go 61mph
a Yamaha blaster can go around 75-80
Stock straight off the line would prolly go 60-70 mph but if tuned it can go faster easily.
155mph
very slow the rmz,yzf,kxf,sxfwill beat it easy
Not that fast but about 50 with no upgrades
