Yep the Corse wheel is different as the bike uses a larger axle, I had a 16.5 inch Dymag but as it had the larger Corse Centre hole I sold it to Phil Bevan for his 996RS, But I'm not sure if the locating pins are on a different PCD as I didn't try it or measure it but I think I have seen a Corse wheel on a standard hub using a one piece nut come reducing sleeve |
