Blew my chain off while riding yesterday

I am generally very meticulous with the maintenance of my motorcycles, and in particular my chain. I had inspected and lubricated the chain about 300 miles prior, but yesterday on my ride home from work the chain broke off and few into the ditch (taking my carbon fender and rear brake line with it).

Admittedly, I was riding a little aggressively, but I have never had a chain break on me before. I ordered new high quality chain, sprockets, and cush, along with new hardware. Anything else I should check while I am working on it? Is there something that could cause an otherwise ok looking chain (from the outside) to snap?

I bought the bike last fall and I don't know how long it had the aftermarket chain on, but the whole bike only has 3000 miles. They kept the stock sprockets it appears, and just added a gold chain (unless they came with the gold chain?)

Bike is a 2000 996.

YIKES! Unless you can find the chain you may never know, but it sure could have been an improper master link installation. I have beaten the daylights out of chains and never had one come apart....that said, I have snapped the occasional kevlar belt....

glad you, or anyone else, were not hurt when she came undone.

Did the chain have a proper rivet joining link like the original had or a bicycle chain type clip link?

Whatís wrong with a clip type, anyway ? If your wheel is in alignment and the clip is on correctly Iíve never seen an issue with them .

Rivet type master links, on the other hand, if not done correctly, are almost guaranteed to fail. I had one recently on which the pins cracked as I attempted to press them. Had I not noticed it would probably have failed. The cracked mushroom end was brittle and came off easily.

It did not have a circlip style master link, it was a rivet type. I have to admit I didn't inspect the link to see how well they had fastened the rivet.

I purchased the case guard today with the rest of the kit. It was on my "to do list" but I hadn't installed it yet. I got super lucky and it didn't damage the case at all. Just a scratch under the countershaft sprocket.

There isn't much to take a photo of. The chain is gone, the sprockets look fine. Trust me, when it snapped it went flying. I could feel a slap by my left boot and I looked in my side mirror just in time to watch it go flying out the back.

Luckily no one got hurt. I have never had such a thing happen to me, but I have top shelf components coming to make sure it never does again!

Just how I feel, but after 44 years of riding I've never thrown a clip style master link chain. I just don't feel confident in the rivet style... seems more likely it could be done "poorly"... I'm an old fart, I know.

D.I.D makes good master links if youíre going with the rivet type. I havenít been comfortable with most of the other brands. I still prefer a clip, done correctly. Iíve never broken one or had one come loose on the street or dirt. Someone will have to explain to me why the rivet type is better in language I can understand. Use small words and pictures please.
