:x Recently an idiot 200lb friend of mine decided to get on the back of my R6 by putting all his weight on the left pillion footpeg, there was a rather sickening creak and now the rear frame seams out of alignment. With the bike on a paddock stand I've measured the distance from the floor to the footpegs and also from the floor to the luggage pins and the bike is 4mm lower on the left side.

Has anyone else had this problem?

Do I need a new subframe?

Can it be straightened? If so, can I do it myself as I'm a competent mechanic?

Rest assured I gave my friend a good kicking.

R6's rule!

Can't recall if those are removable subframes or not.......if they are.....I would think you could make up 4mm diff by putting it in a vise & giving it a bit of the Persuader treatment :wink:

I would ask Yamaha for advice on this, just to be on the safe side. If the subframe is detachable you could straighten it, but this will also weaken it more.

I could be tempted to ask an idiot 200LB friend to put his weight on the other footpeg.
