2025 Arctic Cat M 400 ALPHA ONE 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.
