Capability

• PLUSH SUSPENSION: Thanks to the well-developed suspension tuning, the Wolverine X4 XT-R 850 provides a plush, well-damped riding feel that further improves cabin comfort.
• SMOOTH AND POWERFUL TWIN-CYLINDER ENGINE: The Wolverine X4 XT-R 850 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.
• RESPONSIVE AND RELIABLE 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: Industry-exclusive three-position On-Command® 4WD system lets you switch between 2WD, limited-slip 4WD, and 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 various types of terrain.
• COMPACT AND NIMBLE CHASSIS: Designed for maneuverability, the Wolverine X4 XT-R 850 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 XT-R 850 boasts plenty of ground clearance and big approach and departure angles to clear challenging terrain. For enhanced response in though terrain, the rear A-arms minimize camber changes across the suspension travel.
• YAMAHA CHIP CONTROLLED-THROTTLE (YCC-T): The Wolverine X4 XT-R 850 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.
• PLUSH FRONT SHOCKS WITH SELF-LEVELING REAR SUSPENSION: The Wolverine X4 XT-R 850 features well-damped suspension at all four corners for enhanced chassis control and handling feel. The front piggyback shocks are fully adjustable for spring preload, rebound and high- and low-speed compression damping to allow tuning to suit a wide range of drivers and conditions. Built for Yamaha by KYB®, these front shocks give the Wolverine X4 XT-R 850 a flexible, balanced ride character, whether the day calls for cargo carrying or trail blasting. The Wolverine X4 XT-R 850 also 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.
• MAXIMUM VERSATILITY: In addition to comfortably seat four adults, the Wolverine X4 XT-R 850 features an ingenious storage system for cargo flexibility. By folding and sliding the rear seats forward, the rear area expands and can transport up to 600 pounds with its multiple steel tie-down points to secure cargo or tow a full 2,000 pounds.
• ADVENTURE PRO READY: The Wolverine X4 XT-R 850 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. With Yamaha’s uniquely integrated software, the Adventure Pro system displays advanced vehicle data with exceptional clarity.

Comfort

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 each with newly designed shoulder bolsters and toolless-adjustable seat belts provide a comfortable perch for everyone on board, even with four adults. More importantly, the Wolverine X4 XT-R 850 offers plenty of foot room, including in the rear seats, with soft touch knee areas which feature stadium-style seating and enhanced visibility. Multiple cup holders, high-traction floorboards and an quick-adjust driver seat and steering column round out the amenities.
• SUPERIOR MUD PROTECTION: The upgraded, fully-enclosed doors and high, wide fenders ensure that mud and rocks stay outside the cabin, so you and your passenger can enjoy the ride even more.
• LED LIGHTING: The Wolverine X4 XT-R 850 features LED headlights and taillights for brilliant visibility, long life and minimal power draw.
