I pulled my wheel off for a tire change today and saw some weird wear pattern and damage. Never seen this before. Any idea what went wrong?
KTM 690 SMC, this sprocket replaced the worn OEM at 17,000 miles. It is now 9,500 miles later.
520 chain and sprockets, same 16:42 as OEM when replaced.
This was the sprocket I bought and installed. Is this "lightweight" sprocket weaker than average? Are they race only? Light but faster wear?

Could I have kicked up some gravel that chipped a tooth and the broken tooth strained adjacent teeth until the failure propagated like a zipper?
Are big cc thumpers normally harder on drivetrain than inline-4 or flat-6 motors?
Front wear pattern
