About 74 according to dirt rider. A stock wr with gears can hit over 100.

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.

the only way a yz will do 90mph is if its geared at 15/42 or being towed by a wr.
