Capability

• SMOOTH AND POWERFUL TWIN-CYLINDER ENGINE: The Wolverine X4 850 R-Spec is powered by an 847cc DOHC eight-valve parallel-twin engine featuring a full range of advanced Yamaha technology. 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. Rubber engine mounts and a geared counterbalancer ensure 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 wear, and a sprag clutch delivers natural all-wheel engine braking.
• 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 850 R-Spec 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 850 R-Spec boasts plenty of ground clearance and big approach and departure angles to clear challenging terrain. For enhanced response in tough terrain, the rear A-arms minimize camber changes across the suspension travel.
• YAMAHA CHIP CONTROLLED-THROTTLE (YCC-T): The Wolverine X4 850 R-Spec 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 and speed-sensitive response for minimized fatigue.
• ADVANCED SELF-LEVELING SUSPENSION: The Wolverine X4 850 R-Spec 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. High performance KYB® piggyback shocks up front offer full adjustability.
• 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 the ability to comfortably seat four adults, the Wolverine X4 850 R-Spec features an ingenious storage system for cargo flexibility. By folding and sliding the rear seats forward, the rear cargo area expands and transports up to 600 pounds with the multiple steel tie-down points to secure cargo. It also boasts a towing capacity of up to 2,000 pounds.
• ADVENTURE PRO READY: The Wolverine X4 850 R-Spec 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.

Multiple cup holders, high-traction floorboards and an quick-adjust driver seat and steering column round out the amenities.
• PLUSH SUSPENSION: Thanks to the well-developed suspension tuning, the Wolverine X4 850 R-Spec provides a plush, well-damped riding feel that further improves cabin comfort.
• 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 passengers can enjoy the ride in any conditions.
• LED LIGHTING: The Wolverine X4 850 R-Spec features LED headlights and taillights. LED headlights offer brilliant illumination of the trail ahead while LED taillights increase visibility from behind, helping to make you more conspicuous in dark or dusty conditions.

Confidence

• INDUSTRY’S MOST DURABLE CVT: The Wolverine X4 850 R-Spec transmission uses its own cooling intake to maintain proper temperatures, an oversized belt to handle the torque of the large engine 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 industry's 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 850 R-Spec powerplant is able to handle the toughest conditions without complaint.
• FULL UNDERBODY SKID PLATES: To ensure gnarly terrain doesn’t stop you, full skid plates protect the entire underbody of the Wolverine X4 850 R-Spec, from the front differential to the rear gear case.
