I'm not exactly sure when it happened, but I think it was on a hillclimb get off and the bike went upside down and hit pretty hard on that side.

 

I've tweaked my sub frame a few times. It's actually cut down some a little now. Next summer when it's too hot to ride I may brace it up some and get the frame powder coated. It is not that hard to straighten it back out so your fender looks straight again. I use a 15" crescent, a 3/4" drive socket and breaker bar, and sometimes, gently, a wooden mallet to get things back they way they should be.

 

Any time I have a doubt about why I bought this type of bike, I turn to threads like this.

Bang it back it, quick and dirty. It's literally good as new. This bike doesn't have pretty welds, and stuff like this gives it character. It's badass.

I shudder to think what I'd do in the same situation with another type of bike.

 

It's actually not as crude as it sounds. They also makes tools for straightening sub frames. I take my time and when finished, depending on how mangled things got, you can't tell there was any damage. The sub frame bends very easy. It wasn't until mine got bent and twisted very bad that I cut out the end and straightened the rest so I could mount a fender and go ride. Had I had more time I probably would have done it a little different. It is not uncommon to bend or break the sub frame on off road motorcycles. Many actually have bolt on sub frames which makes repairing or replacing easier.
