a stock can go about 60 to 65 and a one with racing parts on it about 65 70
I have a 2004 Yamaha yz 85 and can get it to go about 64mph and i weigh 135. What i like most is that it picks up quick in only 6 seconds its toping out so overall great bike
Stock 55-60
a yz 85 goes about any where between 60 and 70 m.p.h
I would say 85-90mph
Like 70mph
fast
Over 85 mph ! ! ! Hang on ! I backed off the gas and it still had more left ! with 30hrs on the ski .
if it is a Yamaha wolverine 450 it will go 61mph
As fast as it can.
a Yamaha blaster can go around 75-80
155mph
my friend has a 2001 model (no difference) and we used a radar gun to test it. on flat paved ground (the atv is stock) it went 85. beat that. just to show that rednecks can go faster than regular people!
