Me and my bud want to set up one of our bikes for supermoto, the main investment is obviously the wheels, and since his KTM is an 04 it has the 26mm axle on the front and my berg has the 20mm. we can only afford one set of wheels so we have been trying to decide which one we buy the wheels for. well i found the solution, in the KTM hardparts catalog is an adapter set to use 20mm axles with forks made for 26mm axles, so we can buy a set of wheels for my bike and the adaptors will allow us to run them on his!
