Vehicle Information
Moto-Ski Grand Prix 634 Snowmobile (1970-1971)
The Moto-Ski Grand Prix 634 is an iconic performance snowmobile, produced from 1970 to 1971. Positioned as a premier model, it was renowned for its power and distinctive design. The 634 model was equipped with a 634cc Hirth engine, producing 36 horsepower, making it one of the fastest snowmobiles of its era. While the Grand Prix 634 did not feature distinct trim levels beyond engine choice, significant changes were implemented between the 1970 and 1971 model years. The 1971 models received a complete redesign of the nose and cowling, which now hinged at the front. Other improvements included the introduction of a handlebar-mounted kill switch, a larger track shaft diameter, and spoke idlers replacing solid ones. The Grand Prix retained its all-black seat, despite seat color changes on other models. Q: How can I ensure these parts fit my Moto-Ski Grand Prix 634?
