Vehicle Information
Polaris Colt 340 Snowmobile (1972-1978)
The Polaris Colt 340 and Colt SS 340 snowmobiles were produced from 1972 to 1978, establishing themselves as popular trail models. These sleds were consistently powered by a twin-cylinder, free-air cooled "Star" engine, with displacements ranging from 333cc to 340cc across the years. While specific horsepower figures varied and are not always readily available, the engine platform remained a core feature of the series. A notable evolution occurred in 1973, when the Colt series underwent a significant redesign. This included updated styling, adopting cues from the 1972 TX race sleds, and crucial mechanical upgrades. Standard features from 1973 onwards often included Polaris Torque-O-Matic clutches, a hydraulic disc brake, and a slide rail track suspension, bringing race-inspired technology to trail riders. Further refinements, such as an innovative Torque-Balance Drive System and enhanced track features, were highlighted for the Colt SS 340 in 1977. FAQ:
