2019 Yamaha Wolverine 850

The tight trail conquering Wolverine X2 R-Spec boasts proven off-road performance with superior capability, comfort and confidence.

• Capability

The Wolverine X2 R-Spec is powered by an 847cc DOHC, eight-valve, parallel twin-cylinder motor that features the full range of Yamahas advanced performance technologies. Forged pistons and connecting rods ensure durable high-rpm performance, with Yamahas 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.

Yamahas Ultramatic transmission is the most advancedand durableCVT 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 X2 R-Spec, a robust clutching system features an oversized belt for durability under aggressive riding, while still maintaining low cruising rpm for smooth, quiet running.

Yamahas 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.

• Comfort

Thanks to helical-cut drivetrain gearing, the rubber-mounted and counterbalanced engine, and a variety of noise- and vibration-reducing inserts around the cabin, the Wolverine X2 R-Spec 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.

With high-backed seats, each with shoulder bolsters and automotive-style three-point seat belts, the Wolverine X2 R-Spec provides a comfortable perch for driver and passenger. A standard sun top, multiple cup holders, high-traction floorboards and adjustable driver seat and steering column round out the amenities.

The Wolverine X2 R-Spec is one of the smoothest and quietest side-by-sides ever made. Noise, vibration and harshnessNVH in engineering termsis minimalized thanks to the refinement of the twin-cylinder powerplant as well as an array of specially-formed body panels and insulating dampers throughout the chassis.

• Confidence

The Wolverine X2 R-Spec transmission uses its own cooling intake to maintain proper temperatures, an oversized belt to handle the torque of the large motor, and Yamahas unique sprag clutch to maintain constant belt tensionthe end result is a drivetrain built for years of trouble-free service that leaves the competition in the dust.

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 X2 R-Spec powerplant is able to handle the toughest jobs without complaint.

Skid plates protect the entire underbody of the Wolverine X2 R-Spec, from the front differential to the rear gear case, to ensure gnarly terrain doesnt stop you. And as with other Yamaha machines, the skid plates include convenient service points to access fluid drain locations without removing the guards.
