Hello guys, I bought my Ninja 400 in March 2020, and I'm using it as my daily commute. I already rode 9500 k.m. Yesterday when I'm coming back home I broke my chain. There was no issue at all, no weird sounds or anything, just "clank" and broke. I have cleaned my chain a month back as well.

So did anyone has the same issue like this? Is this a common problem? Because I've never heard that chain breaks like in only in 10000 k.m. I've put some photos as well.
Please guys let me know.

I am on 13,000 km's and none near that situation.
BTW, those same frame sliders bended my frame tube when I took a slide. Might take them off.

I have no answer, never seen a link break like this. Usually the post and rollers break or a master link fails. Glad you're are ok but your plastic parts took a beating. Guess I'll start shopping for a new chain soon. Thanks for sharing.

A lot of folks here are using the D.I.D
Brand chains. There are a couple of choices in that brand. I like the ones i used

That sucks and could've been really dangerous. I've heard a couple of instances of chains breaking but mostly on dirt bikes or a dragster throwing a chain.

I kinda have to point this out that your chain shows a lot of rust spots which points to a lack of maintenance/lubrication certainly leading to accelerated wear. Quality chain/sprocket set and regular cleaning/lubing weekly and/or 500~800 kms is generally good practice.

@Saurabh Sutradhar, do you live near the ocean? Salt from the water can get in the air and can cause premature rust.

You are right, I cleaned the chain about a month ago...but after I didn't ride that much so I thought it will be fine...but that was a mistake I guess...馃槶
