2018 Yamaha Wolverine X4 Realtree Xtra & Aluminum Wheels

The Proven Off-Road Wolverine X4 now brings Real World Tough trail exploring to the whole family with an all-new four-seat tight trail conquering configuration.

• All-New Twin-Cylinder Engine

The Wolverine X4 is powered by an all-new 847cc DOHC, eight-valve, parallel twin-cylinder motor that features the full range of Yamaha’s advanced performance technologies. Forged pistons and connecting rods ensure durable high-rpm performance, with Yamaha’s 270° Crossplane Concept Crankshaft for linear torque development and excellent power throughout the rpm range. To improve efficiency, the engine features a dry-sump design for a more compact layout and offset cylinder block to reduce friction loss, while rubber engine mounts and a geared counterbalancer ensures smooth running from idle to redline.

• Ultramatic Transmission

Yamaha’s Ultramatic® transmission is the most advanced—and durable—CVT drive system available. An automatic centrifugal clutch maintains constant belt tension for reduced belt wear and a sprag clutch delivers natural all-wheel engine braking. In the Wolverine X4, a robust clutching system features an oversized belt for durability under aggressive riding, while still maintaining low cruising rpm for smooth, quiet running.

• On-Command 4WD

Yamaha’s renowned On-Command® 4WD system lets you switch between 2WD, limited-slip 4WD and a fully locked differential 4WD. Unlike competitors’ automatic 4WD systems, On-Command puts the driver in full control to make the most of available traction in any sort of terrain.

• Smooth, Quiet Powertrain

Thanks to spiral- and helical-cut drivetrain gearing, the rubber-mounted and counterbalanced engine, and a variety of noise- and vibration-reducing inserts around the cabin, the Wolverine X4 is one of the smoothest and quietest recreational side-by-sides ever built. Sneak through trails without disturbing nearby animals, or simply enjoy the improved refinement after a long day riding on the trail.

• Roomy Four-Person Cabin

With four high-backed seats, each with shoulder bolsters and automotive-style three-point seat belts, the Wolverine X4 provides a comfortable perch for everyone on board, even with four adults. More importantly, the Wolverine X4 offers plenty of foot room, including in the rear seats, which are mounted slightly higher than the front row for stadium-style seating and enhanced visibility for all. Multiple cup holders, high-traction floorboards and adjustable driver seat and steering column round out the amenities.

• Plush Suspension

Thanks to the well-developed suspension tuning and self-leveling shocks, the Wolverine X4 provides a plush, well-damped riding feel that further improves cabin comfort, all without the need to adjust suspension to suit the changes in load every time you add or remove cargo.

• Industry’s Most Durable CVT

The Wolverine X4 transmission uses its own cooling intake to maintain proper temperatures, an oversized belt to handle the torque of the large motor, and Yamaha’s unique sprag clutch to maintain constant belt tension—the end result is a drivetrain built for years of trouble-free service that leaves the competition in the dust.

• Reliable Engine Lubrication and Cooling

With a large oil capacity circulating in the dry-sump system, a liquid-cooled oil cooler, and a large radiator with integrated blower, the Wolverine X4 powerplant is able to handle the toughest jobs without complaint.
