2025 Arctic Cat MOUNTAIN CAT

The 2025 Arctic Cat M 858 Mountain Cat Alpha One is a single-rider mountain snowmobile built for deep snow and technical backcountry terrain. Its 858 cc two-stroke engine and ALPHA ONE single-rail rear suspension provide a purpose-built platform for climbing, carving and sidehilling through unpacked snow. Multiple long-track configurations provide different balances of manoeuvrability and flotation for tighter terrain or deeper conditions. The adjustable mountain chassis is suited to remote backcountry routes, steep approaches and full days in powder. It fits experienced riders looking for a dedicated deep-snow machine with a responsive mountain-focused setup.
