Trailing arm bolt diameter? thread pitch?

[MtnMax600]

I need to go buy a trailing arm bolt for my friend and cant remember what size it is and the thread pitch. I think the pitch is 1.25...or is it 1.75? Anyone?

12M - 1.25 x 55mm

That is for the rear attach point.

Exactly what I needed, thanks Ding.

If you are not going to use an OEM bolt for the trailing arm pivot, then you should definately get a Grade 8 bolt. Don't just use a plain old mild steel bolt.
