    Source for rear pistons

    Does anyone know of a source for rear caliper pistons for a 77' gs750 Stateside?

    All I can find online are UK dealers.

    Thanks.

    Whenever this has come up in the past, the solution has been to find a way to order from the UK or to order a couple of calipers from fleaBay and hope the pistons are in usable shape. I don't believe anyone has found a US source.

    I would check with Z1 Enterprises. They do quite a bit of business in the UK, and in any case, they're experts at tracking down old bike parts.

      They should be available from any OEM parts supplier. I bought mine from Parts Outlaw. It's #1 in the diagram with part number 69100-08821.

        +1. Partzilla also lists it as available and in stock.

          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.

            Chuck, I think he was looking for "Caliper Pistons" not "Cariper Pistons" ha ha.

            FYI the kits are a bit mislabeled, 1-2 is the piston and seal kit, (not piston and pad kit) If you need pads, that's 2-1.

            Good luck,

            David.

              Thanks guys. I looked at a few OEM sources online and they where they were unavailable, so I assumed that was the case everywhere.

                I found them in the UK on the interweb, and they are stainless steel.
