Bent Sub-Frame

8 posts in this topic

I have an '08 YZ450F and wrecked in on Memorial day weekend. Bent the exhuast, handlebars, and sub frame. I was wondering if the sub frame could be bent back? or if anyone knows a good way to bend it back? Thanks for the help.

I use a pry bar, 2x4, deadweight hammer to fix

this will work well also

Sorry bout the crash! The easiest way I have found is to cut the cross bar that is by the fender. This is what makes it rigid when all the bolts are removed. You can have your way with it then. Another good thing is an auto body tool, it is a long bar with hooks and a chain that lets you pry things back in shape.
