An Extension of Your Instincts

If you ride deep powder, you need a snowmobile that’s built to a higher standard. With the ultra-agile CATALYST™ platform and your choice of ALPHA ONE® mono-rail or twin-rail suspension, this lineup floats, climbs and carves with purpose.

Powerful and Responsive
400 SERIES EFI ENGINE
A 397cc single-cylinder 2-stroke engine with electronic fuel injection (EFI) offers quicker, more responsive power that gives you a smoother take off every time.

397cc, Liquid-Cooled, 2-Stroke EFI Engine with 65+HP
With an industry-first design that’s compact and lightweight, this EFI engine brings 65-hp and 397cc performance to every ride, all while remaining under 50 lbs. A 3-stage exhaust valve system takes this power to the next level, delivering improved throttle response and better overall engine performance. As a liquid-cooled engine, it thrives in low-snow conditions – and a counter balance shaft eliminates most engine vibration. The result—a lightweight-but-mighty power source that fuels a ride like no other.

Unmatched Control
ALPHA ONE SINGLE-BEAM REAR SUSPENSION
ALPHA ONE Suspension is the only single-beam rear suspension in the industry, providing enhanced agility in deep snow. The lightweight, single-beam design provides nimble action, allowing riders to maneuver the sled and carve tighter circles with less effort than conventional, dual-rail snowmobiles.

Proven Suspension
ARCTIC MOUNTAIN SUSPENSION
AMS™ 37 Front Suspension is built to deliver confident performance in deep snow, combining lightweight spindles with precision-engineered suspension geometry for responsive control and maneuverability. Forged-aluminum spindles reduce drag while maintaining predictable handling in variable conditions. Paired with hydraulic twin-tube shocks and durable dual-phase alloy-steel A-arms, AMS provides smooth bump absorption and reliable performance when deep snow demands more from your sled.

Arctic Mountain Suspension
AMS is our proven, lightweight front suspension system utilized on all of our full-size mountain sleds. This system keeps the sled nimble in the varying snow conditions of the backcountry and provides optimal off-trail cornering, as well as more predictable counter steering when side-hilling. Paired with front and back hydraulic twin tube shocks, AMS provides excellent bump absorption. Plus, the lightweight, forged-aluminum spindles sit at a 27 degree spindle caster angle, providing optimal ski camber for off-trail cornering and more predictable counter-steering when side-hilling. They’re built to reduce drag, while the durable dual-phase alloy-steel A-arms are tailor-made to maneuver in deep snow.

Features May Include:

Light and Nimble
Mid-Size Chassis

• The M 400 mid-sized chassis is extremely lightweight, making it agile and easy to handle, no matter your skill level. With a lightweight mountain seat and a short tank, this sled makes transferring weight while cornering effortless.

Smooth Power Delivery
Arctic Drive System

• The lightweight, low-maintenance Arctic Cat M Belt Drive System has a CVTech Trailbloc drive clutch and CVTech Invance driven clutch to deliver power to the snow. It also provides more low-end power and throttle control, which is needed when navigating deep snow.

Easier Steering
G2 PROCLIMB Skis

• The lightweight G2 ProClimb™ 7-inch Mountain Ski is tapered to stay on top of the snow. The ski works in tandem with the AMS spindles for easier steering and better deep snow performance.
