    Hi.

    I bought a used Triumph street twin about 2 months ago. 14,000 miles on it. I was riding yesterday, going about 50mph and the chain snapped. The chain was flung out the back of the bike. Took a small chunk out of the frame, ripped off one of my rear turn signals off and brushed past my hip on the way out. Lucky it didn't take a chunk out of me.

    So, now I am trying to figure out what to do. After looking around online a bit, it seems the best thing to do is replace the sprockets in addition to buying a new chain. Also cross my fingers that the chain didn't slam the motor on the way out, I don't think it did via my eyeball inspection, but I am not positive.

    Anyway. Was wondering if you had any suggestions on new sprockets and chain to buy. Maybe take the opportunity to upgrade.

    And yes... I know, I know,... I will be more attentive to chain maintenance.

    Thanks

    Bit of a bummer for you mate and not a great start. I usually go for the gold ring chains. But all good chains these day should do the job. Just make sure they have the o'ring's for better oiling or fit a scot oiler.

    X chains for me.

    I like the gold links but that is aesthetic.

    get the sprocket set recommended for your bike - best not to bugger about with changing ratios unless you know (or think you do) what ur doing.

    Id go for a rubber mounted front sprocket to reduce snatch.

    Fit and maintain well - you escaped lightly. Learn from that lesson.

    Now check everything else on the bike - brakes, oil, filers, spark plugs, bearings (everywhere), etc…

    Glad you got away with it relatively lightly. The weakest part of the chain is usually the part where it has been joined and I guess that’s where yours has failed, usually a riveted link. As has been said buy a good quality set and maintain it properly and it will last you a good many miles.

    Looks like you got off light with that! I've seen a chain punch a hole in a crankcase and lock the rear wheel. Was the chain joined with a split link? They're convenient bit nothing like as strong as a rivet type link and if the chain is slack............ 'nuff said. Buy the best quality chain & sprockets you can afford. I'd go D.I.D chain and JT sprockets and if you really want to look after your chain, fit a chain oiler.
