    Marzocchi Shock - GS1000

    Hi, I have a pair of Marzocchi shocks but when I went to fit the bottom mounting seems incorrect. I cannot get the shock mount to fit over the standard swingarm bush, seems to be about 0.5mm too small, also the "thread" on the shock mounting that you use to tighten the bolt against looks like it has been drilled.

    Looks like these are not the correct shocks for a GS1000, are there any markings on these shocks to indicate which bike they are for.

    Cheers

    0.5mm is negligable, file the inside face until it fits nicely. if the threads have been damaged or "modified", use a longer bolt with a nut on the back.

    Just remember, an opinion without 3.14 is just an onion!

        They only made one fitment of those Strada shocks and they should fit straight on. Maybe yours have been slightly twisted or bent, or the bush on the swinging arm has been replaced with something slightly longer. Either way, as Adrian says, 0.5mm is nothing so just file it off. The longer bolt with the nut is ok as well.
