Vehicle Information
Arctic Cat ZR 858 Snowmobile (2024-2026)
The Arctic Cat ZR 858 snowmobile, available for the 2025 and 2026 model years, is built on the innovative CATALYST platform. It is powered by an 858cc, 2-stroke, liquid-cooled C-TEC2 twin-cylinder EFI engine. This powerful engine, estimated to produce between 170 and 183 horsepower, represents an 11% increase over the previous C-TEC2 800 engine, placing it firmly in the "165-class" for performance. While the CATALYST chassis was introduced in 2024 with 600-class engines, the ZR 858 variant debuted in 2025, marking a significant evolution for the model line. For the 2026 model year, the 858 engine received notable upgrades to enhance performance and durability. These include an average 26% increase in oil supply across the operating range, revised fuel mapping and ignition curves for broader engine operation, and a sealed airbox. Additionally, the CATALYST chassis for 2026 858 models features revised engine mounts with a new rubber durometer and orientation on the magneto side, specifically designed to reduce vibration. Various trims, including Sno Pro and R-XC, are offered for these model years. FAQ:
