Hydraulic valve lash adjusters ease maintenance and liquid cooling increase overall engine durability. Plus, the engine itself is rubber-mounted within the double-cradle, high-tensile steel frame to reduce vibration at the handlebar and footpegs.

A low-maintenance shaft drive transmits power from the five-speed transmission to the beefy 15-inch rear wheel.

Air-assisted rear shocks with four clicks of rebound damping adjustment offer a smooth and controlled ride, while dual front discs provide reliable stopping power.
