    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

    I can't recall either.
    It's on an M24 thread?
    30 seems light, 32?

      If it's a 24 mm thread the average size of socket would be 36 mm unless it is a suzuki special 19mm
      There is a list that you can look at https://www.enerpac.com/en-us/traini...and-bolt-sizes

            Depends which nut you have... some are bigger. The 1150 one (which is supposedly a harder material) is 32mm I think. The others are 36mm from memory.

                They are all compatible... As far as I know only the 1150 one is different & smaller (but also fits)

                    Yep Ape sell a hardened one... as per my post above the 1150 one is also supposed to be a hardened upgrade over the rest.
