Me too! (front only and only on one side of the hub, the right-hand side). They were there from at least the 600 service (or I just hadn't noticed before) and hasn't got any worse in the last 13,000 miles or so.
Actually not had one. I talked to them about it when I was in last and had a look round the showroom bikes. They all had these marks on. It's clearly part of the production process and whilst it looks a bit poor I reckon it is what it is.
