Real World Tech Yamaha’s advantages are easily seen in the technology found in every Wolverine X4®: Yamaha’s driver-centric On-Command® 4WD, ultra-reliable Ultramatic® CVT, and industry-leading Electric Power Steering.
Advanced Suspension System Plush, well-damped suspension perfectly balances comfort with chassis control and bump absorption. Advanced self-leveling rear shocks automatically adjust for changes in vehicle and passenger loads to ensure ideal chassis performance with every ride.
Potent 847cc Twin-Cylinder Powerplant Featuring drive-by-wire throttle, a 270-degree crankshaft design and lightweight internals, the Wolverine X4 shares technology with Yamaha’s class-leading sportbikes, for thrilling performance on every ride with unmatched smoothness and refinement.
Room for Four With high-back seats and plenty of legroom, the Wolverine X4 offers comfortable, secure seating for four full-sized adults. The second row is raised for excellent visibility, with comfortable handholds and three-point seatbelts for each seat.
Versatility Unequaled The Wolverine X4 offers a balance of work-ready capability, refined comfort and trail-proven confidence that confirm Yamaha is the ultimate outdoor adventure partner.
Smooth and Powerful Twin-Cylinder Engine The Wolverine X4 is powered by an 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 an offset cylinder block to reduce friction losses, 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. The robust clutch features an oversized belt for durability, while 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 full diff-locked 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.
Compact and Nimble Chassis Designed for maneuverability, the Wolverine X4 chassis is super agile, making tight trails a breeze, with lightweight steering to select the ideal line when tackling obstacles. With an upswept underbody design, the Wolverine X4 boasts plenty of ground clearance and big approach and departure angles to clear challenging terrain. For 2020, the rear A-arms are redesigned to minimize camber changes across the suspension travel, for enhanced response in tough terrain.
Yamaha Chip Controlled Throttle (YCC-T) The Wolverine X4 engine utilizes YCC-T®, a drive-by-wire system that converts the driver’s commands into digital throttle control. Throttle response is further improved thanks to a quick-response servo motor, precision fuel injectors, and a high-volume airbox with two-stage air filtration.
Class-Leading Electric Power Steering Yamaha’s Electric Power Steering (EPS) provides the industry’s best balance of steering assist and positive feedback, with light steering, speed-sensitive steering response, and minimized fatigue.
Self-Leveling Suspension The Wolverine X4 features self-leveling rear shocks that automatically adjust to changes in vehicle load. Not only does this system maintain ideal chassis geometry and eliminate the need to adjust shock preload, the system is completely self-contained and requires no heavy air compressors or electric motors.
Powerful All-Wheel Disc Brakes Large 207mm vented disc brakes with two-piston calipers provide exceptional stopping power on all four wheels, with excellent feel and minimal noise.
Maximum Versatility In addition to the ability to comfortably seat four adults, the Wolverine X4 features an ingenious storage system for cargo flexibility. By folding and sliding the rear seats forward, the rear area expands and transports up to 600 pounds, with multiple steel tie-down points to secure cargo. And a full 2,000 pounds of towing capacity.
Adventure Pro Ready The Wolverine X4 comes pre-wired for Yamaha’s exclusive Adventure Pro® GPS system, unlocking the next level of trail-ready navigation. This state-of-the-art GPS unit combines a range of functions into a single, rugged 7-inch full-color display. Search, download, record and share trail routes. Challenge your friends to time trials on saved courses. And with Yamaha’s uniquely integrated software, the Adventure Pro system displays advanced vehicle data with exceptional clarity.
Smooth, Quiet Powertrain 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 X4 is one of the smoothest and quietest recreational side-by-sides ever built. Sneak through trails without disturbing nearby animals, converse with your passengers, or simply enjoy the improved refinement after a long day riding on the trail.
Roomy Four-Person Cabin Four high-backed seats with shoulder bolsters and automotive-style three-point seat belts provide 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 feature stadium-style seating and enhanced visibility. Multiple cup holders, high-traction floorboards and an adjustable driver seat and steering column round out the amenities.
Plush Suspension Thanks to the well-developed suspension tuning, the Wolverine X4 provides a plush, well-damped riding feel that further improves cabin comfort. 2020 updates also increase rear suspension travel, enhancing bump absorption.
Superior Mud Protection Fully-enclosed doors and high, wide fenders ensure that mud and rocks stay outside the cabin so you and your passengers can enjoy the ride even more.
LED Lighting The Wolverine X4 features LED headlights and taillights, for brilliant visibility, long life and minimal power draw.
Accessory Ready With nearly 600 watts of electrical output from the engine, two standard 12V DC ports and four pre-wired accessory switches, the Wolverine X4 is ready for a wide range of accessories and add-ons.
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 and is backed by the industries only 10-Year V-Belt Limited Warranty.
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.
Full Underbody Skid Plates Skid plates protect the entire underbody of the Wolverine X4, from the front differential to the rear gear case, to ensure gnarly terrain doesn’t stop you. The skid plates also include convenient service points to access fluid drain locations without removing the guards.
Complete Instrumentation The all-digital meter gives the driver a complete picture at a glance, with a large dimmable readout. Vehicle status and warnings are clearly displayed, along with easily accessed odometers and trip and hour meters.
Speed Management System The Wolverine X4 also comes standard with a Speed Management System which allows the owner to limit the vehicle to a top speed of 25 mph, ideal for work sites or other special operating conditions.
Built Real World Tough®, Assembled in the USA As with other Yamaha ATVs and Side-by-Sides, the Wolverine X4 is assembled in the USA to meet Yamaha’s exacting standards for durability and reliability.
NEW FOR 2020
