I do drive pretty hard opening the throttle quickly and doing 100+ mph from time to time but still that's what these things are made for right?

If you bought it from B&C then it'll be genuine, so we can rule a fake sprocket out. Personally I would contact them and show them you photos and see if you can wangle a replacement out of them. There's a small chance you've got a duff one that missed out on the hardening or anodising process. I would expect to see at least 6000 miles out of a Renthal aluminium sprocket and even then I wouldn't expect it to look as bad as yours does at the moment.

I don't think his problem is down to the fact it's aluminium. Yes, you can expect half the mileage of a steel sprocket, there's no dispute that they don't last as long, but 1200 miles is plain ridiculous!
