I took my left rear wheel off of my Raptor today and I noticed that on the left frame or tube of my swingarm, it looks like there is a concave or "bowed in" shape to it.

It's hard to describe, its not that the swing-arm is bent, it's like the tube is bowed in just a bit instead of being perfectly flat. The right side has a similar shape, but not as much.

The area that I'm talking about is just ahead of the rear sprocket, opposite the right side that has a bracket to hold the brake lines.

This probably made no sense to anyone, but if it did, please take a look and tell me what you found.

Thanks,
Scott

 

Just looked at mine, couldn't really see anything but I could feel where it is bowed in. Appears to be the way it was manufactured. It is bowed in parallel to the ground.

 

I dont think that your swingarm is bent, because mine and my friends are both like that. I think it is a mfg design, sometimes a bend if put into a piece of metal to give it more strength
