Went to work on the bike alittle today and noticed the rear sprocket looked like this. WTF! I dont know whats causing it. I cant guess how many miles are on the sprocket. maybe 10K...no clue since I never get to really ride anymore. I usually adjust the chain every few rides or so. And I use chain lube on it every 600 miles...again im lucky to ride 200 miles a month these days. My gf does enjoy riding and shes been riding 2 up the last few times i've gotten the bike out. chain tightness/slack is in spec. front sprocket looks good compared to rear sprocket.
