Spain’s BeOn Automotive has developed a kit capable of converting popular 450cc motocross bikes into single-cylinder road racers for little effort and cost. The concept isn’t new, Roland Sands Designs has been making single-cylinder racers for some time now, and the racing class is alive and well in Southern California, but having a bolt-on kit like this is much needed first. Like the RSD SuperSingles, the Project 450GP kit utilizes the stock frame frame and engine, and only swaps components like the suspension, bodywork and wheels.
