    Chain Breaking

    Anyone else ever actually break a chain? I was cruising up the road one day and with a rattle, my chain departed from the bike, and I was free-wheeling. This was a 630 chain on a '82 gs1100e. Dunno why it broke. It never gave me a clue that it going to go, and I never did figure out just why. It wasn't high-mileage, or high wear that I could see. Anyone else got a story like this?

    Doubtful it broke
    Master link came apart

    Was it a clip master link, or a press fit?

      This was an endless chain, no master link. It was broke.

        Photo of the broken ends would be interesting to see.

        Any chance battery acid got on it? I've never actually seen a chain that broke, as opposed to the master link coming apart.

          So this was the original 36 year old chain? I could be wrong, but the only endless chains I see, are factory installed chains. If it was original and it was endless you would have to remove the swing arm to install it, not something you see as a replacement. If it was still the original chain, well that may explain why it broke.

            This happened in the late '80s sometime. I'm pretty sure it was the OEM chain, and the mileage was under 15k at the time.

                  If your chain simply left the bike, consider yourself VERY LUCKY.

                  There have been countless stories of chains jamming against the crankcase, damaging them, as well as others locking up the rear wheel, causing some rather exciting moments.

                    Chain broke on a CB200 but it was the master let go.
                    Was riding pillion on a CB250N at 60 mph when the chain jumped the rear sprocket and locked the back wheel but it didn't break.
