2025 Yamaha WOLVERINE X4 850 SECAPABILITY

The Wolverine X4 850 SE 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.

2025 Yamaha WOLVERINE X4 850 SECOMFORT

Four high-backed seats each with newly designed shoulder bolsters and tool-less-adjustable seat belts provide a comfortable perch for everyone on board, even with four adults. More importantly, the Wolverine X4 850 SE 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.

2025 Yamaha WOLVERINE X4 850 SECONFIDENCE

The Wolverine X4 850 SE 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.
