Vehicle Information
Ski-Doo Formula Mach 1 670 Snowmobile (1993)
The 1993 Ski-Doo Formula Mach 1 670 was a prominent snowmobile of its era, recognized for its powerful 669cc (often rounded to 670cc) liquid-cooled twin engine, which produced approximately 118 horsepower. This engine, a Rotax 670 RAVE, positioned the Mach 1 as a high-performance option for enthusiasts. The 1993 model year brought significant updates to the Mach 1. The engine displacement increased from the 617cc used in previous models (1991-1992) to the more powerful 670cc unit. This year also saw the introduction of an upgraded C-7 rear suspension and a wider 40-inch ski stance, enhancing control and stability. While the Mach Z became Ski-Doo's new top-tier performance snowmobile, the Mach 1 remained a strong contender. Two trims were available: the standard Formula Mach 1 670 and the Formula Mach I XTC, designed for enhanced trail versatility and performance. Q: How do I ensure this product fits my 1993 Ski-Doo Formula Mach 1 670?
