2018 Yamaha Wolverine X4 | Parallel Twin Engine

Heart of the Wolverine

Yamaha’s goal with the engine in the Wolverine X4 was to make it quiet, compact, controllable and quiet with low vibration.

The 2018 Wolverine X4 is powered by an all-new 847cc DOHC, eight-valve, inline twin-cylinder motor. It idles at a low 1300 rpm, and a high-end muffler is also used to quiet down the Wolverine X4.

The air-filter system was designed so intake air noise is reduced, and the Ultramatic CVT is set to upshift at lower rpms. To improve efficiency, the engine features a dry-sump design, which also allows for a compact layout.
