A New Breed of Power

858 Engine

The 858 two-stroke engine is designed for seamless integration into the new CATALYST platform. With an 8% increase in displacement, this engine houses an 11% increase in output over the C-TEC2 800 and weighs 4% less. It features an optimized air intake system, a new exhaust valve design for more consistent power and cleaner emissions, and an all-new crankcase for increased stroke and integrated engine mounts.

Peak Performance Unlocked

CATALYST Chassis

The revolutionary CATALYST platform has been built from the ground up to optimize every aspect of your ride, so much so that you’ll feel at one with the sled. With enhanced ergonomics, a lower center of gravity, our exclusive laydown engine design, specially calibrated suspension and more, this changes everything.

Keep Yourself Planted

Twin Rail Suspension

The twin rail braced suspension is built for one thing: carving and climbing with control. With two braced rails, it delivers a solid, predictable feel that keeps the track straight and the power locked in — even when the hill gets rutted, windblown or near vertical. Compared to single rail setups, it’s less flickable but more planted — perfect for riders who’d rather hold the line than play around it.

Quickly Connect

ATACH Latching System

Adding accessories to your sled is a snap with this 4-point latching system. You can install and remove accessories in seconds, so no matter where you are, you can customize your sled with ease.

Smooth Power Delivery

ADAPT CVT System

With its lightweight, narrow design that increases performance and belt life, as well as the industry’s only self-adjusting clutch, the ADAPT™ CVT system provides better throttle response, smoother power delivery and a ride like no other.
