Vehicle Information
Ski-Doo Olympique 335 Snowmobile (1970-1972)
The Ski-Doo Olympique 335, a classic snowmobile produced from 1970 to 1972, was powered by a consistent single-cylinder, two-stroke Rotax 335cc engine, delivering approximately 20 horsepower in its final year. This model was offered in two primary trims: the standard Olympique 335 with manual start, and the Olympique 335/E (or 335E) which included an electric start system. Although the engine displacement remained constant, the Olympique 335 underwent notable mid-cycle updates. The 1971 models featured a significant restyling, introducing structural improvements, a full console, deeper seats, and a new plastic gas tank, replacing the previous metal version. Further enhancements arrived in 1972, including a new ball joint steering system, a longer brake handle, and a raised side handle, improving rider experience. These changes highlight a continuous evolution within the 1970-1972 production run, rather than a complete generation overhaul. FAQ:
