2026 Arctic Cat RIOT 400 POWERFUL AND RESPONSIVE

400-SERIES EFI ENGINE

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.

With an industry-first design that’s compact and lightweight, this EFI engine brings 65-hp and 397cc performance to every ride, all while remaining under 50 lbs. A 3-stage exhaust valve system takes this power to the next level, delivering improved throttle response and better overall engine performance. As a liquid cooled engine, a counter balance shaft eliminates most engine vibration. The result—a lightweight-but-mighty power source that fuels a ride like no other.

SLIDE-RAIL REAR SUSPENSION

This responsive rear suspension uses a full 12.5 inches of travel to absorb any bumps on the trail. With support like this, every ride will be so stable and smooth, you won't even notice the rough snow.
