I read in jodycross action that the top speed on a bone stock YZF was 88mph and 96mph for a WR. But like IO said that info came from jodycrossaction

My geared up YZ400 hits 80 at the rev limiter, confirmed by a truck speedometor. Maybe they tested a geared up bike but I know my YZ won't go over 80, even with the 1 tooth more on the front sprocket. The stock bike won't come near 80 till gears are added. I'm not sure about the WR.

A YZ426 will not do 94 mph stock, period. If a YZ can go that fast, than my WR426 can go 85 in fourth gear...half throttle.
