Yamaha has taken the covers off of a brand new four-seat Sport-Utility Side-by-Side – the 2018 Yamaha Wolverine X4.

Don’t go thinking the Yamaha Wolverine X4 is just a stretched out version of the two-seat Wolverine; it is so much more. In fact, Yamaha outfitted its newest machine with an all-new 857cc Parallel Twin cylinder engine, which produces 69 horsepower – a big jump up in power from the 708cc Single in the original Wolverine.

The new Yamaha Wolverine X4 also boasts some cool technology in the rear, as the rear seats fold up and slide forward. With the seats folded down the cargo bed can hold up to 600 pounds. Add in 2,000 pounds of towing capacity and the Wolverine X4 should be a willing work companion.

Interestingly, the Wolverine X4 shares a very similar footprint to the two-seat Wolverine. It is just 4.1 inches longer (122.0 in.), 1.6 inches wider (62.2 in.) and 3.0 inches taller (77.2 in.). As well, the wheelbase is just 1.4 inches longer at 82.7 in.

Other features on the new Yamaha Wolverine X4 include self-leveling rear shocks that automatically adjust to changes in vehicle load, independent double-wishbone front and rear suspension, preload-adjustable front and rear shocks, and 10.7 inches of ground clearance.

“The Wolverine X4 sets a new standard in recreational off-roading, combining Yamaha’s industry-leading durability and reliability with proven off-road capability in a quiet, compact and nimble four-seat Side-by-Side chassis,” said Mike Martinez, Yamaha’s ATV & SxS group vice president. “Yamaha designs, engineers, manufactures and tests its ATV and Side-by-Side vehicles in the real world, allowing Wolverine X4 owners to confidently realize their off-road adventures with family and friends.”

Capability: Unmatched Off-Road Performance in the Widest Variety of Terrains and Conditions.

Leading the way in tight, technical terrain, the Wolverine X4 is powered by an all-new 847-cc DOHC, eight-valve, parallel twin-cylinder motor. Forged pistons and connecting rods ensure durable high-RPM performance, and Yamaha’s 270-degree crankshaft format allows 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 an offset cylinder block to reduce friction loss, while rubber engine-mounts and a geared counterbalancer all but eliminate vibration at idle and throughout the RPM range.

Ultra-smooth power delivery is offered up via Yamaha Chip Controlled-Throttle (YCC-T®), a new drive-by-wire system providing precise throttle control. Throttle response is further maximized by an innovative ‘high-response’ servomotor for ultra-fast throttle application, 12-hole fuel-injectors, and a high-volume airbox with two-stage air filtration. The Wolverine X4 also comes standard with a new Speed Management System, which limits the vehicle to a top speed of 25 MPH by simply turning a (removable) key, making it ideal for work sites and other specialized operating conditions.

Additional Real World Tech features include Yamaha’s exclusive Ultramatic transmission – the most advanced and durable CVT drive system available, On-Command 4WD giving drivers control over switching between 2WD, limited-slip 4WD, and a fully locked differential 4WD. All Wolverine X4 models are equipped with Yamaha’s EPS for the industry’s best balance of steering assist and positive feedback from the terrain.

For added ease-of-use in a multitude of driving situations, the Wolverine X4 features new self-leveling rear shocks that automatically adjust to changes in vehicle load, maintaining ideal chassis geometry and eliminating the need for shock preload adjustment. The system is completely self-contained and requires no heavy air compressors or electric motors. The motion of the vehicle itself pressurizes the shock’s internal valves, for an ideal chassis setup on every ride.

With an upswept underbody design, wide arc A-arms, and an overall 10.7-inches of ground clearance, the Wolverine X4 boasts ideal approach and departure angles to help traverse challenging terrain. Additionally, the Wolverine X4 is equipped with independent double-wishbone suspension, providing 8.7 inches of preload-adjustable travel in front and 8.9 inches in the rear, for excellent handling feel and bump absorption. And delivering exceptional stopping power on all four wheels with superb feel, the Wolverine X4 boasts large 207-mm vented disc brakes with two-piston calipers.
