Rotax 850 E-TEC® Turbo engine

technology, starts the engine.
Shorter tunnel length without snowflap for greater deep snow capabilities with more clearance and lighter overall weight. Standard rear fender with LinQ-ready attachment points.
Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons. Ultra-responsive shifting, impressive RPM consistency and lightweight.
Improved profile running boards
Front to back extruded grid-style board allowing snow to pass easily through, preventing washout and trenching, plus clears footrests for grip. Flatter foot position for comfort and control.

All-digital LCD gauge cluster with flatter viewing angle for an easy-to-read info center whether standing or sitting.
