Moto-Ski Grand Prix 399 Snowmobile (1971)
The 1971 Moto-Ski Grand Prix 399 was an iconic snowmobile, known for its specific performance-oriented configuration. This model was powered by a 398cc JLO engine producing 28 horsepower. The 1971 Grand Prix lineup also offered other engine options, such as the Grand Prix 338 (with a 338cc JLO or 338cc Hirth engine) and the powerful Grand Prix 634 (with a 634cc Hirth engine). These variants allowed enthusiasts to choose the power level suited to their needs. The Grand Prix 399 positioned itself as a balanced choice within this lineage. To find the exact parts for your 1971 Moto-Ski Grand Prix 399, please use our year and model selector at the top of the page. The 1971 season marked a significant redesign for Moto-Ski snowmobiles, including the Grand Prix. The nose and cowling were completely redesigned, with the cowling now hinging at the front. The front suspension was improved with a single-pin anchor for the leaf springs, and a handlebar-mounted kill switch was introduced for the first time. Changes were also made to the track system, with an increased shaft diameter and spoke idlers replacing the previous solid idlers. These modifications modernized the Grand Prix 399's appearance and functionality for this model year. FAQ:
