Default Frame Straightening Help

I have a '93 F2, and the rear section of my bike is a bit off set from a dump a while back. It really shows from the back of the bike. My licence plate is off centre to the right. The wheel alignment is fine. Its more cosmetic then anything. Im just wonder the best and easiest way to straighten it back. Thanks.

If it were me, I wouldnt even bother trying to straighten out the subframe. I'd buy a good used one on ebay. They run between 50 and 80 bucks usually. thats about as easy as it gets, just replace it.

Agreed. You'll probably never get it straight, and you can get a new one off of ebay and get it welded onto your bike for a pretty fair price. I'd pony up and just get a new one.

Heh yea..

If I had a bent subframe it's still the way I'd go. There's stock SF's that have been hacked off on ebay and it should be a basic job to take to a welder and have the old one cut off and the new one welded on. If you want it straight and strong, just get a "new" subframe imo.

what about using a metal bar, and trying to "bend" it back? I'm thinking that if I wedge it between the side rail and the swing arm, I might be successfull.... good idea?

I agree with chuck and squid , but if you were to try and bend it back you really have nothing to loose, and as this is just the tail/subframe area , however remember aluminum usually olny takes a minimal amount of bending before it will break, and at the weld especially, becareful not to cause more damage to other components during yer process, in the end , a new subfrme is the way to go....JMO

Well the subframe's still steel on these bikes so it's not as hazardous as if it was an aluminum on but it's still gonna be real tough to get back to true. There's crossmembers all up and down the subframe and getting a pipe around them to bend it back could be tough. Having some kind of torch would help a lot. Hell, can't hurt to try...

Still prob best to pick up a chopped, straight subframe
