Bent Sub Frame

Recommended Posts

Had a good crash on Sunday and tweeked my Sub Frame on my 05 CRF® pretty good. Looking at stock ones they are over $300. Is there any after market company that is making them at a lower price?

AC racing makes them cheaper than that. Or you might find a used stocker on ebay. For a temp fix you can straighten yours. It will bend easy next time, but it will work for awhile.

Seems like I'm seeing alum. sub frames alot when surfing or thumbing through the mags looking for something...they're out there...

But I gotta ask...how did your muffler&mid-pipe end up?

I saw a MX mini-review of a Jardine Ti subframe an issue or two back. They said they wouldn't replace a good stocker with one but they would use it to replace a bent one. Since Ti is flexier than Al it might be less prone to future bending. I'll see if I can find that issue & review.

My sub frame must be bent, the rear fender tilts down to the right side, and my new exhaust didn't bolt up correctly, see pictures by going to links below. This is how the bike was when I bought it, also notice the broken seat bracket. Should I try to bend that subframe peice up? it appears to be bent down towards the end. thanks.

The back fender also looks like that on my CR 250, not as bad though.

Here it is... July 06 MXA. Jardine Ti subframe, but its for CRF250. They gave it 4 stars, the fit was spot on. Price says $460 (ouch). Jardines ph (951)739-5900.

Take your muffler off put a floor jack on top of your tire and jack your subframe up straight. Its is easier and more accurate then jumping on it.

Going strictly from appearance, it looks to me like it's bent just forward of the weld where the angled support ties into the top frame member. Being unfamiliar with the pre-06 models, it's hard to tell for sure, but could it also be bent in that angle support just forward and below the mid pipe mount?

Best method to straighten a sub frame: Put bike it in back of PU truck with pipe on, park next to big tree, put long 2x4 against frame by swing arm bolt to the tree, wrap come-along or ratchet winch arond sub-frame and tree and crank away, go just a little past straight and walla. I've seen some pretty messed up sub-frames come back to life. 04CRF450's really work well.
