PARITY IN DIRT TRACK

Fort Worth, Texas–The K&N Filters Pro Series sanctioned by Formula USA has put parity back into dirt track motorcycle racing. After 3 of the 9 race series there have been three different winners with four different brands of motorcycles in the top four K&N Filters point standings.

Formula USA developed the Pro Single National Championship as the premiere class of the K&N Filters Pro Series. The rules have been developed around production-based motorcycles making the series more attractive for sponsorship support from manufactures, aftermarket companies and motorcycle dealers. The variety of brands, bright colors and sounds of the single cylinder 4-stroke engines has also appealed to spectators.

“We are on target with our dirt track program,” says Mike Kidd a V.P. of Clear Channel Motor Sports. “After top-level professional dirt track racing this season on Pro Single motorcycles, even the critics have been amazed at the speed and competitiveness of the riders and motorcycles.”

The bikes of choice have been the Honda CR450F, Yamaha YZ450F, KTM 450SX, Suzuki 400 DRZ and Harley-Davidson/Buell Blast. Aftermarket companies are developing dirt track kits, making it easy and cost effective to build and maintain a competitive dirt track motorcycle.
