Vehicle Information
Ski-Doo Valmont 640 Snowmobile (1970-1972)
The Ski-Doo Valmont 640, produced from 1970 to 1972, was a robust snowmobile known for its reliable performance. It was consistently powered by a 635.1 cc (or 635 cc) Rotax 2-cylinder, 2-stroke, fan-cooled engine, delivering approximately 35 horsepower throughout its production run. This model was a staple for riders seeking a dependable machine for winter adventures. While the core engine remained unchanged, the Valmont 640 saw variations in its trim levels and drivetrain. Notably, Valmont models in 1970 and 1971 incorporated a gearbox, a distinct feature compared to the chain case used in other contemporary Ski-Doo models. Trim options evolved, with the 1970 model often appearing as the Alpine Invader 640/ER, while 1971 and 1972 offered specific Valmont 640E (electric start) and 640ER (electric start with reverse) configurations. Q: How do I ensure I'm selecting the correct parts for my 1970-1972 Ski-Doo Valmont 640?
