The F4 Sidewinder used a 238cc engine which was similar to the motocross F21M. However, the F4 was also well equipped for trail riding which was a rapidly expanding market in America. Quick-Detachable lights and off-road trials were some of the highlights. The rotary valve engine produced 23 horsepower @ 7,500. | The [[Kawasaki]] F4 Sidewinder used a 238cc engine which was similar to the motocross F21M.
