That's quite a wild lookin setup you have there motogps, I don't know if I would trust something like that whilst I was riding. Anway, I ended up cutting some thick tubing to 90mm to make a riser that fitted between the tripple clamp and the bar mount. Doesn't sound like much but I'm happy with it now. Only problem is now the thread of the bar mounts only has a little bit to hold onto.
I am actually really happy with he YZ250F, coming from a 2003 CR125. Better brakes, suspension and power. Any one else have his bike?
