Cooper (motorcycles)

[1][2] As the baby boomer generation came of age during the 1960s and 1970s, off-road motorcycling experienced a surge in popularity.

[2] Although Cooper addressed most of the reliability issues, the brand's poor reputation persisted.

[2] The combination of a poor reputation along with a higher than anticipated price caused the company to cease operations after producing approximately 1,200 motorcycles.

Jones competed on an Ammex motorcycle during the 1976 250cc motocross national championship with his best result being a 10th place at the Sears Point race.
