2025 Yamaha Wolverine X4 850 XT-R

An extreme edition for extreme adventures, complete with factory-installed WARN® winch, Special Edition paint, color-matched wheels and aggressive tread pattern GBC® Dirt Commander® tires.

Features may include:

• 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.

• 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.

• 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.
