500 Can-Am -1976

No business like snow business

The huge Bombardier industrial group is one of the world's biggest manufacturers of snowmobiles; engines are supplied by its Austrian subsidiary, Rotax. In 1973, Bombardier's Canadian factory at Valcourt decided to enter the motorcycle market and its Can-Am 125 and 250 sparked a real revolution in American off-road circles.

Rotary Inlet Valve

The prototype appeared on Canadian racetracks in 1975 and used an unorthodox power unit. It was a compact horizontal twin designed for snowmobiles by Rotax; it developed 60-85 hp in standard and racing tune. Its most original feature was a rotary intake valve mounted above the gearbox and driven by a train of gears. The biggest task in converting the engine for motorcycle use was replacing its automatic transmission by a fivespeed box. The engine was suspended from a girder frame and its compact dimensions allowed the fuel tank to be housed under the saddle on the road version; the dummy tank served as a luggage box.

Killed by the Anti-Smog Lobby

The definitive roadgoing version appeared in 1976 and was so full of promise that public opinion saw Bombardier as a potential challenger to the Japanese. But the antipollution

laws decided otherwise. They banned this 500 in the United States from 1980 and Bombardier wisely decided to halt production after scarcely four years rather than make the huge investment that would have been necessary to comply with the regulations.

The short but brilliant career of this major Canadian industrialist in the two-wheeler world was frustrated by hostile legislation.
