“I don’t like how much mud gets thrown up on my back with the ‘08 and later KTM off-road bikes. So I cut some curved sections from a one-gallon, oval oil bottle. I used nuts and bolts to attach the extensions, but you could use pop rivets just as well. The difference is huge in muddy conditions, and the cost is almost free. Lifting it gets even tougher after I’ve added my fender extensions. But all late-model KTMs have two holes in the right-side rear number panel to access the muffler mounting bolts. A length of nylon strap can be threaded through the holes. I put a washer on the muffler bolts, then run the blots through holes melted in the strap. Leave a little slack and you have a perfect lift handle.”

-Engine Head Mount Changed
Instead of one center-biased head mount for the motor, the 2010 Yamaha YZ250F gets two side-oriented mounts. This is a big tuning area in frame design. Engineers at Yamaha told us that even the shape, angles and thickness of the piece of aluminum spanning from the motor to the frame makes a huge difference in the chassis balance and feel.
