The F200 OHV concept was established to fill several needs that karting and other small engine motorsports groups here in the U.S. will need to address in the coming years. Originating in the oval sector of karting, F200 has made significant inroads into sprint karting and is gaining acceptance in other small engine motorsports programs.

F200 Benefits:
Create a truly universal engine formula that will be cost effective and affordable, Much longer engine life than current 4 cycle classes, No "gray areas" and nit picky "judgment calls" like the one engine "spec" classes Run modern overhead valve engines that are considerably more durable and are made from much higher quality standards
