PLENTY OF POWER TO PLAY

400-SERIES EFI ENGINE

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.

Arctic Cat Snowmobiles - Mountain Sleds - M 400

UNMATCHED CONTROL

ALPHA ONE SINGLE-BEAM REAR SUSPENSION

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.

LEARN MORE

PROVEN SUSPENSION

ARCTIC MOUNTAIN 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.

LEARN MORE

SMOOTH POWER DELIVERY

ARCTIC DRIVE SYSTEM

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.

LIGHT AND NIMBLE

MID-SIZE CHASSIS

The mid-sized BLAST 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.

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.

RELIABLE TRACTION

CHALLENGER TRACK

The Challenger 146-inch track with 2-in lug offers the traction needed to conquer varying backcountry conditions. Its benchmark lug design is versatile for all-around performance and features a saw-tooth lug for additional grip on hard, wind-blown and springtime snow.

READY TO GO

TURN-KEY ELECTRIC START

Simply sit down and take off. The M 400 features a turn-key electric start, so there's no need to pull-start this mountain sled.
