We used Mag 7 for support of our KTM525 at the 05 1000 and I had no issues getting my wheels and air filters back. One of the members of Mag7 even brought them to me in Las Vegas and refused to take the money I offered him for his trouble.
They also helped us change an engine clutch side case at pit 8 and did a bang up job while I sat by the fire having an energy drink.
Hats off to MAG 7.
Maybe I got lucky, or maybe they have gotten better than your experience!
