Finally found the crash damage! Rear sprocket.

I do not recall. That is likely a very high quality chain. You do not have to spend 100$ on a chain, you could get something like this;

not sure if thats the exact model but I have used 3 RK chains on supermoto bikes over the last 2 years (I have had like 4 different bikes) and no issues. RK is available at a local motorcycle shop like a few blocks away so that is what I purchase.

Only reason I say to replace the chain is because the stock chain is absolute garbage and there is many threads on it, I had tons of problems with mine losing tension then getting too tight and having kinks all in the frst 500 miles. Also if the sprocket and chain got whacked then the wobbly sprocket run, could have damaged it and better safe then sorry.

That is all I got for ya I cannot remember the length I purchased I think 118 which was a few links long.

+ 1 For RK.
I've fitted 4 or 5 of them in a row & have had zero trouble.

I like an o-ring chain, the plain chain stretches wat too fast, even the RK stuff !
