The Mighty Superlites

 
 

                           TMCC SUPERLITE RULES 2009.

The Superlite class has been a valued class of  TMCC Road Racing since it’s inception in 1998. It offers a superb entry level class to the world of road racing, low cost and the availability of competitive machinery make the mighty Superlite a great first choice ( for some , the ONLY choice ! ). These machine are very robust, rarely suffer expensive crash damage and once set up require minimal maintenance. Chassis limitations reduce any advantage that may other wise be gained by horsepower increases, so the emphasis is on a smooth riding style, with a machine that behaves itself most of the time. This is the 3rd incantation of the Superlite rules for the TMCC, as the club and class has grown over the years, so the rules have evolved accordingly. 
 
        1.   Classes: One class, divided into two grades: Pro and Amateur.

          Lap times to be determined at the first meeting of the year, laps time will be monitored throughout the year. A rider that moves up a grade will take all points
          earned to a maximum of second place in the next class.
