so i can not say much on wear but i have used these sprokets for years and they hold up very well. For $20 it's not to bad considering this sprocket is taking a beating from that big 500. I had a 13T on my 690 smc and it lasted a year of hard riding.
It is not the sprocket we are concerned about in terms of wear. The 13t sprocket causes the chain to wear and rub more on the swing arm pivot where there is a plastic wear block. That slide or wear block appears to be rapidly wearing such that the chain may soon cut through and start damaging the swing arm.
