75mph stock, if its race tuned, high 80s if your giving it some 2) Mine is stock, I weigh 150 pounds and it runs 88-92mph depending on the weather...most yfz450s run 85-90mph but some aren't tuned as good out of the factory as others...stock the slowest probally is around 70-75...so they range from 70-90mph but on average I would say 85mph
the yfz 450 is not that fastest quad, Its not far from the top but raptors have more top speed. there is no 250 that will stand up to a yfz 450 stock
About 82mph stock! Very trustworthy ATV I would recommend.
A 2012 stock yfz 450 goes about 75 maybe 80 and the 2012 stock raptor 700 goes 75-80 The yfz would win in a race to full speed because is accelerates faster and it weighs less
I heard the Suzuki has more top end speed but the YFZ is quicker
Approximately from what I've found 90 to 120.
YZF 450 puts out 39 hp stock.
if all quads are stock then the kfx and yfz will be quicker than the 700 but the 700 wil win in the long run because of its massive top speed, IMO the kfx will beat the yfz
the yfz would be better. Your garbage i kill modded out yfzs WIth my stock ltr 450. SUZUKI RULES!!!!!!!
Stock Horsepower is around 39hp.
61 mph
39.5
top speed wise. Yes. Accerealetion wise not at all.
