  • Trick digital instrument panel boasts a multifunction LCD display with speedometer, odometer, dual tripmeters, hour meter, 4WD status, transmission position, clock and fuel gauge.
  • All-wheel independent suspension, a thick, cushy seat and light handling make for a supremely comfortable ride.

  • Specially designed full stainless steel exhaust system features aluminum heat shields and a screen-type spark arrestor for great power with minimum noise output.
  • Override button allows engine to make maximum RPM in full Diff-Lock mode.
  • Compact engine design features a 45° cylinder angle for maximum ground clearance and lower seat height for quick steering and maneuverability.
  • Gear-driven crankshaft balancer shaft and rubber-damper engine mounts reduce vibration.
  • Large-capacity aluminum radiator with fan-assist delivers maximum cooling efficiency and is positioned high in the frame for optimal protection.
  • Low-maintenance front shaft drive features a gear case and electronic servo-activated 2WD/4WD/Diff-Lock via the On-Command® system.
  • Direct rear shaft drive eliminates the U-joint for great durability and more efficient power transfer at all RPM.
  • Sealed drive case keeps out water and debris to help prevent belt from slipping.
  • Easy-access, tool-free air-filter box.

  • 7.1 inch front suspension travel and 9.5 inches out back, controlled by five-way preload adjustable shocks, provide a comfortable ride whatever the load or trail conditions.
  • 11.8 inches of ground clearance and full-length composite skid plate deliver maximum underbelly protection while enhancing terrainability.
  • 34.6-inch seat height for excellent handling and maneuverability.
  • 25 x 8-12 front and 25 x 10-12 rear tires on, lightweight aluminum wheels further boost ground clearance while reducing unsprung weight for lighter, responsive steering.
  • Heavy-duty front carry bar and CV joint guards protect against rock and debris damage.
