Mid-size. Major fun.
Mountain riding just got a lot more interesting. The Arctic Cat M ALPHA ONE will revolutionize how you explore the backcountry with the groundbreaking CATALYST platform.

Features may include:

Plenty of power to play
Previously known as the BLAST M 4000, the M 400 is equipped with a 397cc single-cylinder 2-stroke engine with 65-class horsepower and electronic fuel injection (EFI) offers quicker, more responsive power that gives you a smoother take off every time.

Unmatched control
ALPHA ONE Suspension is the only single-beam rear suspension in the industry, providing enhanced agility on the mountain. 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
The Arctic Mountain Suspension (AMS) is built specifically to navigate through deep snow. With lightweight spindles and precision engineered suspension geometry designed with mountain riding in mind, AMS optimizes your performance in deep snow.

Smooth power delivery
The durable Arctic 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.
