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.
