Vehicle Information
Arctic Cat Riot 858 Snowmobile (2025-2026)
The Arctic Cat Riot 858, available for the 2025 and 2026 model years, is a high-performance crossover snowmobile built on the innovative CATALYST platform. Powered by a new 858cc C-TEC2 2-stroke engine, it delivers a "165-class horsepower" twin, representing an 11% increase in output over its predecessor. This model is offered in various trims, including the foundational Base, the shock-focused Sno Pro (featuring AC5S shocks for 2025 and optional G8 digital display for 2026), and the ATAC, which boasts FOX iQS shocks and the G8 touchscreen gauge as standard. Track options evolved from 2025 (1.35-inch Cobra or 1.75-inch Hurricane) to 2026, where only the 1.75-inch Hurricane track is available. For 2026, the Riot 858 received significant refinements. The 858cc engine underwent recalibrations, increasing oil flow by 26% and revising fuel mapping and ignition for broader operating range. Chassis upgrades include new engine mounts to reduce vibration by 50% and a lighter, more rigid composite Track Control Link (TCL) for improved clutch alignment. All Catalyst crossover models also gained an upgraded snow flap. These enhancements ensure a more refined and durable riding experience. Q: Will this part fit my 2025 or 2026 Arctic Cat Riot 858?
