1976: Made exclusively by Scorpion, Massey-Ferguson announces the 340 liquid-cooled Cyclone patterned after the innovative Brut. Company brochure. Courtesy Brad Goodenbour. Massey described the machine as follows: Want a little something extra in your snowmobiling? This is the one - a fast, sleek, high-performance cross-country competitor. The Cyclone features a slide suspension for sure-footed traction, and either a 340 (2-cylinder) or 440 (3-cylinder) Brooten liquid-cooled engine. First proven liquid-cooled power plant in the snowmobile industry, the Brooten engine can run all out without overheating-thanks to a heat exchanger cooled by snow. There's a Mikuni carburetor for each cylinder-the same kind of carbs used for motorcycle enduro racing. And the modified Power Pac clutch is both torque and speed sensing, to deliver an unusually high ratio of horsepower to the track. So when you crack that throttle wide open, you'll know you've got a Cyclone under you. See Terms of use. Link to Home.
