The Mickey Thompson Tires MIROCK Superbike Series has posted a $1,000 Cash Bonus to the first Harley Davidson motorcycle that wins in any class at a MIROCK event. The MIROCK Superbike Series offers nine different classes that many v-twins may compete in from Heads-up classes to E.T. classes to Index classes. This is a one-time cash bonus that is awarded to the first Harley Davidson or Buell that wins a class. Buell motorcycles are also eligible for this cash bonus. This cash bonus will go into effect at the FBR Shop Spring Bike Open at Rockingham Dragway on March 22-24, 2013 and will remain in effect at every MIROCK event until a Harley Davidson / Buell wins the prize. If the cash bonus doesn’t get awarded in 2013, it will remain in effect for 2014, and so on and so on. The MIROCK Superbike Series welcomes all Harley Davidson and Buell racers to our series and good luck hunting for the MIROCK cash purses.
