my 2000 wr 400 totaly stock with 17 tooth front, went 165kph before the speedo needle just bounced around, could'nt read it. 165kph = 103mph
that was on the road but a bit scary, was shaking and wobling.

My 08 read 96 on the speedo. That's not GPS, so I don't know how accurate that was. I've done the free mods, and had it rejetted. That's with my 250 pound fat butt on it.
