Mammoth Maxx was established in 2004 . Partners Charles Howard and Jeff Tunnell had prior custom motorcycles experience; each previously owned more than one Yamaha VMAX Motorcycles and Charles has been a custom car builder since 1999. With this knowledge and the uprising demand for metric motorcycles, the decision was made and Mammoth Maxx was created.

Mammoth Max is a complete aftermarket shop for all Yamaha VMAX motorcycles. Additional services offered are custom powder coating, custom seats and cadmium plating
