NHRA Finally Makes Good on Pro Stock Rule Disparity

The NHRA made its first formal move in addressing what was a glaring rules disparity between Harley-Davidson V-twins and the rest of the Pro Stock bike field, officially banning four-valve motorcycle engines effective in 2013. This move was made to address a performance advantage and exclusivity issue that has been a dark cloud on the class for the last couple of years.

For the past few years, Vance & Hines was the only company producing the Harley-Davidson V-Rod motors that powered their race team's Pro Stock Bikes, ridden by Andrew Hines and Eddie Krawiec. The V&H team has won a shocking 13 races in a row dating back to last October, which already accounted for one rule change this year, and a second (a minimum weight increase of 10 lbs) was just announced.
