2027 Arctic Cat® M 400 ALPHA ONE

Mid-Size. Major Fun.

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.

Features may include:

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.

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.

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.
