Yamaha Wolverine RMAX 1000 Engine Rebuild Service (2021–2023 2-Seat & 4-Seat Models)

The Wolverine RMAX 1000 is built for versatility—trail riding, hauling, and everything in between. Over time, internal wear can lead to reduced power, rough operation, or inconsistent performance. A full rebuild brings everything back into proper working condition.

At REV6, your engine is completely disassembled, inspected, and rebuilt with corrected tolerances and refreshed components. The result is smoother operation, steady power delivery, and long-term reliability.

Inspection Process

Each engine is assembled by one technician and reviewed by another before it ships. This additional inspection step helps ensure everything meets spec before it goes back into your machine.

Warranty Coverage

Every rebuild includes a 1-year warranty, with the option to upgrade to a 2-year no-fault plan for additional protection.
