Vehicle Information
Ski-Doo MXZ 550 Snowmobile (2002-2014)
The Ski-Doo MXZ 550, produced from 2002 to 2014, is a popular fan-cooled snowmobile known for its consistent 553.4cc two-stroke engine, which delivered approximately 60 horsepower throughout its production run. While the engine remained largely unchanged, the MXZ 550 series saw significant advancements in chassis design. Key platform updates included the introduction of the revolutionary REV chassis in 2003, which repositioned the rider for improved control. This was followed by the lighter and stronger REV-XP platform in 2008, and further ergonomic refinements with the REV-XS platform in 2013. Various trims were offered, such as the MX Z 550 Fan, the sportier MX Z 550 X (from 2006), the MX Z 550 Sport (from 2011), and the MX Z 550 TNT (around 2010-2012), providing options for different riding preferences.

| Drive Belt | Inspect regularly; replace as needed | Check integrity, tension, and wear (separation, fraying, glazing). Typical lifespan: 2 500 to 5 000 km. |
| Spark Plugs | Inspect and replace as needed | Typically annually or per hours of use specified in the manual. |
| Chaincase Oil | Check pre-season and every 50 hours; change annually or end of season | Dedicated lubrication for the drivetrain. |
| Coolant | Check levels regularly | Although the MXZ 550F is fan-cooled, some components may utilize coolant. |
Maintenance intervals may vary slightly by specific model year and configuration. It is essential to consult your snowmobile's official owner's manual for precise information.
