A message from our partners at Moto-Master USA:

Those who attended Powerline Park last year will remember the conditions. With the many challenges and concerns already faced by GNCC riders, rear brake failure should not be one of them.

Fortunately, Moto-Master has what you need to help get your machine mud ready- The Mud Series Rotor; A superior quality, solid rear disc designed specifically to hold up in extremely muddy conditions, taking all the heat and abuse that comes with the toughness of GNCC Racing.
