is a motorcycle producing subsidiary of the Bombardier Recreational Products, a Canadian corporation. In 1973, under the direction and leadership of an American Engineer named Gary Robinson and former motocross World Champion, Jeff Smith working with a team of California desert racers, began producing motocross and enduro bikes using engines provided by the Austrian Rotax company, another Bombardier subsidiary. The machines made an immediate impact with riders winning Gold, Silver and Bronze medals at the International Six Days Trial, a form of off-road motorcycle Olympics. The following year, the company swept the 1974 AMA 250 cc motocross national championship with riders Gary Jones, Marty Tripes and Jimmy Ellis, finishing first, second and third. The bikes gained a reputation for their high horsepower outputs.
