Arctic Cat M 400 Snowmobile (2025-2026)

The Arctic Cat M 400 is a deep snow and mountain snowmobile designed for the 2025 and 2026 model years, built on the CATALYST™ platform. It is powered by a consistent 397cc single-cylinder 2-stroke engine with Electronic Fuel Injection (EFI), delivering approximately 65-class horsepower. For both years, the primary trim is the M 400 Alpha One ES, with color variations (Black/Skye Blue for 2025, Black/Dusk Purple for 2026). The "ES" likely indicates Electric Start.

No significant mid-cycle generation or engine changes are reported between the 2025 and 2026 model years for the M 400. The 400-series engine remains unchanged, and the snowmobile itself is largely consistent with previous iterations, having shed the "Blast" moniker a couple of years prior. This ensures a stable platform across these model years. Q: How do I ensure this part fits my specific Arctic Cat M 400?
