• Industry-exclusive, fully automatic Ultramatic® transmission is the most advanced drive system in ATV-ing. An automatic centrifugal clutch maintains constant belt tension for reduced belt wear, unmatched durability and confident all-wheel downhill engine braking.
• Industry-exclusive three-position On-Command® In/Out 4WD feature lets you switch between 2WD, limited-slip 4WD and fully locked differential 4WD—all with the simple push of a button.
• Fully independent long-travel four-wheel suspension with five-way preload-adjustable shocks and 11.8 inches of ground clearance provides maximum control and comfort over rough terrain.
• Trick digital instrument panel boasts a multifunction LCD display with speedometer, odometer, dual tripmeters, hourmeter, 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.
• Lightweight yet super-strong CAD-designed steel frame results in the lightest weight in the class—600 pounds—which results in outstanding handling and performance.

Engine:

• Yamaha’s patented five-valve cylinder design produces a potent combination of low-rev torque, right-now throttle response and high horsepower.
• 42mm Mikuni BSR carburetor and high-output DC-CDI ignition system ensure incredible throttle response and engine performance.
• Pushbutton electric starting with auxiliary recoil starter and auto decompression cam for “easy-pull” backup starter convenience.
• Dual-range (Hi/Lo) drive with reverse taps into massive pulling power in low and superior performance in high.
• 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-degree 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 greater 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.

Chassis/Suspension:

• Large-diameter ventilated hydraulic front disc brakes and shaft-mounted hydraulic rear disc system ensure outstanding stopping power in a variety of conditions.
• Light, responsive steering and a class-leading turning radius combine for increased comfort and incredible maneuverability — even in 4WD.
• 7.1 inches front suspension travel and 9.5 inches out back, controlled by five-way preload adjustable shocks, provide a controlled, 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 creates a low center of gravity for improved handling and maneuverability.
• 25x8-12 front and 25x10-12 rear tires on, lightweight aluminum wheels further boost ground clearance while reducing unsprung weight for lighter, more responsive steering.
• Heavy-duty front carry bar and CV joint guards protect against rock and debris damage.

Additional Features:
