Watch A Great Ride (1979) Official Trailer

If you can handle the action, it's a great ride

Cocky, overconfident motocross champion Jim Dancer and his more mature and levelheaded bike racing buddy Steve Mitchell decide to trek from Mexico to Canada via an unmarked off-road route. During their eventful pilgrimage the carefree fun-loving (and seeking) protagonists encounter a mixed bag of folks who include a perky middle-aged lady who wrecks cars for a living, two sexy swinging babes, a friendly farmer, and a hotshot aspiring motocross rider teen who challenges Dancer to a race. This latter episode ends in tragedy, with the kid taking a fatal spill off his bike. So the kid's gung-ho militant gun fanatic father decides to hunt Dancer and Mitchell down in his sinister souped-up truck.
