Vehicle Information
Ski-Doo Formula MXZ 470 Snowmobile (1993-1994)
The Ski-Doo Formula MXZ 470, produced from 1993 to 1994, was a renowned performance snowmobile, powered by a Rotax twin engine of 462cc or 463cc. It was primarily built on the new F2000 chassis, offering horsepower in the range of 90 to 100, with variants like the 1994 MXZ-X 470 reaching just under 100 hp. The 1993-1994 period saw significant evolutions. In 1993, the introduction of the F2000 chassis and C-7 rear suspension enhanced stability. 1994 marked the arrival of the MXZ-X 470, a performance-oriented version featuring HPG shocks and upgraded engine components. The Summit 470 was also launched in 1994 as Ski-Doo's first modern mountain snowmobile, boasting a lighter F2000 chassis, a narrower front end, and plastic skis. The 1994 MXZ was also the only model to incorporate a Willwood hydraulic brake. Q: How can I ensure I order the correct part for my Ski-Doo Formula MXZ 470?
