Rotax® 850 E-TEC® engine: Next generation of the most advanced directinjection two-stroke engine technology. Designed for reliability and durability with proven 4-stroke and diesel technologies.
Summit Ergo-Step side panels: Rear section of the panels are ergonomically shaped to support the rider’s shins on downhills. Narrow profile and shape at bottom minimizes "paneling out" in sidehilling. Toe-hold can be added as an accessory.
pDrive™ clutch: Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons on this 100% new clutch. Ultra-responsive shifting, impressive RPM consistency and lightweight.
tMotion™ suspension: A swiveling rear arm and split front arm allow the skid to flex laterally for more predictable carving. More rising-rate motion ratio adds capacity and comfort.
Compact digital gauge: Includes all critical data points in a small, lightweight package positioned perfectly to be seen by a standing rider.
