CAPABILITY
Smooth & Powerful Twin-Cylinder Engine
The Wolverine X4 850 XT-R 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 & 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 & Nimble Chassis
Designed for maneuverability, the Wolverine X4 850 XT-R 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 XT-R 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 XT-R 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 XT-R features well-damped suspension at all four corners for enhanced chassis control and handling feel. High performance KYB® piggyback front shocks built specifically for Yamaha are fully adjustable with spring preload, rebound, and high- and low-speed compression damping, allow tuning to suit a wide range of driver preferences and conditions. Advanced self-leveling rear shocks 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 the ability to comfortably seat four adults, the Wolverine X4 850 XT-R 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 XT-R 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.
Extreme Terrain Tires
Extreme terrain calls for tires that handle the abuse while providing confidence-inspiring grip and feedback. The Wolverine X4 850 XT-R rolls on 27-inch GBC® Dirt Commander radial tires that not only improve ground clearance and traction but feature rugged 8-ply construction for exceptional durability.
COMFORT
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 850 XT-R is one of the smoothest and quietest recreational Side-by-Sides ever built. Converse with your passenger or simply enjoy the unparalleled refinement on extended adventures.
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 850 XT-R 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.
Plush Suspension
Thanks to the well-developed suspension tuning, the Wolverine X4 850 XT-R 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 passenger can enjoy the ride in any conditions.
LED Lighting
The Wolverine X4 850 XT-R features LED headlights and taillights. LED headlights offer brilliant illumination of the trail ahead while LED taillights provide excellent visibility from behind, helping to make you more conspicuous in dark or dusty conditions.

CONFIDENCE
Industry's Most Durable CVT
The Wolverine X4 850 XT-R 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 & 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 XT-R powerplant handles 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 XT-R, from the front differential to the rear gear case. Skid plates also include convenient service points to access fluid drain locations without removing the guards.
Advanced Instrumentation
The premium blue-backlit, all-digital meter with a large dimmable readout gives the driver a complete picture at a glance. Vehicle status and warnings are clearly displayed, along with easily accessed odometers and trip and hour meters.
Speed Management System
The Wolverine X4 850 XT-R also comes standard with a Speed Management System which allows the owner to limit the vehicle to a top speed of 25 mph, making it ideal for work sites or other special operating conditions.
