First sprocket change at 2,350 miles under warranty

The second sprocket was fine but changed to a test steel sprocket at 3,500 miles. Now up to 4,200 miles.

Mainly normal (for a M3W) driving with a bit of track day stuff.

rear tyre still has plenty of tread - the fronts are about 50% worn and I'll be swapping to Blockley's as soon as it makes sense to do so.
