View Full Version : 2009 KX450 Pipe breakage

Need some help getting my SuperTrapp to hold together. I have a 2009 KX450 Flat Tracker. It has broken twice right before the 4" dia. muffler. Once it was running sixth in the Main in Barberville during Bike Week. After getting it welded in Daytona, it broke about 5" toward the mid mount point a few days later. I'm running all the discs and endcap and suspect the extra weight is causing the problem. It has one 4" dia. strap bracket on the muffler to support the rear and I think it's pivoting on the bolted joint.
Please help save this exhaust and Supertrapp's reputation in the Pits.

This pipe has been out there for a couple of seasons now and we really haven't had any feedback involving this issue. You may want to look at how much flex you have in the seat frame, since this muffler is attached to it.

Had a talk with Eric in Engineering and he's working with me to resolve the problem. Pretty knowledgable guy and I'm happy he's come up with some ideas to try. Good customer support from SuperTrapp!
