The biggest news for Arctic Cat mountain customers for model year 2025 is they’ll now have 858cc of displacement to power them in the hills on the Catalyst chassis.

Arctic Cat today unveiled its 2025 snowmobile lineup. Due to last September’s announcements of the new 858 engine and Garmin gauge at the Hay Days event, there weren’t a ton of surprises.

     However, we now know that the mountain lineup gets simplified for 2025 while completely shaking off the ProClimb design. A single-cylinder Blast chassis model will also return for 2025. No word is available yet on the pricing or the exact dates of the ordering period.

     We’ll cover the M lineup below, the Riots here, and the ZR lineup here.

The Cat mountain lineup is significantly simplified for model year 2025. Gone is the ProCross chassis layout. Gone also is the Hardcore lineup. You’ve basically got an M, an M Mountain Cat and an M 400 in the smaller Blast chassis.

The good news is that all full-sized 2025 Arctic Cat mountain sleds will now come in the new, lighter and more agile Catalyst chassis. The great new is that an 858cc twin that Cat said falls into the 165-horsepower class will be an option. Cat fans can rejoice while dreaming of using more power to carve deep powder with a single-beam Alpha One skid.

The base M layout will be available with either the returning 600 twin or the new-for-2025 858 twin. The “regular” package will wear Arctic Cat’s own IFP shocks with a 1.5-inch bore on the 36-inch-wide front suspension and the front and back of the unique Alpha One rear. Buyers of the Sno Pro package upgrade will get the new, five-position AC5S shocks all around, with the Lockout feature available on the rear arm. That allows for a stiffer rear end that comes in handy when climbing steep ascents. We’re still awaiting exact details on the AC5S shocks.

Power Claw track lengths of 146, 154 and 165 inches will again be available, with lug heights varying between 2.6 and 3 inches. ADAPT clutches, a final belt drive and a vertical steering post are other notable features. All of the base M sleds come with a basic gauge.

Those who want Fox shocks and Arctic Cat’s new G8 Garmin-powered gauge will need to step up to the M Mountain Cat line. It is only available with the new, long-awaited 858cc two-stroke twin. Buyers will get Fox FLOAT 3 QS3 shocks all around. They have the option of push-button iQS control at the handlebar or manual control at each shock absorber. The unique Lockout feature is available on either package.

Mountain Cats also get splashes of blue in their graphics package.

Otherwise, Mountain Cats carry the same AWS 36 front and single-beam Alpha One rear suspensions, track options and drivelines as the M machines.

The smallish Blast platform returns as an unintimating starting point for newcomers, teenagers, smaller riders and those who prefer finesse over outright power.

Sixty-five horses are generated by the single-cylinder, fuel-injected engine that was based on the old 800 twin. Its driveline includes CVTech clutches and a chaincase as the final drive.

The track is a 146-inch Challenger with 2-inch lugs. Shocks on the 36-inch front and and Alpha One rear are all baseline hydraulic twin tube units.
