Vehicle Information
Yamaha Mountain Max 800 Snowmobile (1997-2024)
The Yamaha Mountain Max 800 is a high-performance mountain snowmobile with a unique production history spanning from 1997 to 2024, marked by a significant reintroduction. The original 1997 model featured a 791cc 4-cylinder engine and was known for its ProAction Plus long-travel rear suspension and hydraulic disc brake. It was primarily offered as the "MM800A Mountain Max." After a long hiatus, the Mountain Max 800 was reintroduced in 2021, signifying a major generational shift. These newer models (2021-2024) are built on a platform shared with Arctic Cat and are powered by a potent 794cc 2-stroke twin-cylinder engine with Electronic Fuel Injection (EFI) or Semi-Direct Injection (SDI), delivering approximately 165 horsepower. Key updates include a new single-beam rear suspension in 2021, followed by new primary and secondary clutches in 2022, and an improved snowflap in 2023. Trims for this generation include the Mountain Max 154, 165, and the Super Lite (SL) variants. The 2024 models largely carried over with minor cosmetic changes before the series was discontinued for 2025. FAQ:
