Standard right hand metric thread righty tighty lefty loosey after you loosen the two pinch bolts on the left fork bottom 05 thru 09 standards, classics, classic tourers and at least the first year or so of the touring. After 09 I am not sure but its a touring they are there as parts life support, for real rockets
I did have the "switched" thought but the 2 bolts at the bottom would then be backwards and they are not. the calliper mount holes would be backwards and they are not.
Cheers for the help guys. Turns out it was standard thread. Someone had used threadlocker (guessing at the last tyre change) a bit of heat and "hey presto" wheel is off. Now to start polishing....
