Features

Highly evolved, 660cc liquid-cooled, four-stroke ?ve-valve engine and light weight add up to one of the best power-to-weight ratios of any utility model in the industry.

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 con?dent 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 ?ve-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.

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.

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.

Rugged steel cargo racks with special, extra-durable wrinkle paint finish can pack a total of 286 pounds combined (99 front, 187 rear).

Center-mounted, heavy-duty trailer hitch comes standard and can tow over 1200 pounds.

Handy, 12-liter underseat storage box.

Large, 5.3-gallon fuel tank features an electronic, bar-type gauge and easy-access petcock.

Wide, fully integrated floorboards feature serrated footpegs for extra grip in wet conditions.

Large, specially designed seat is extra plush and widely contoured for all-day rider comfort.

Dual 30-watt multi-reflector Krypton bulb headlights with high/low beams feature stylishly sleek cat-eye design; 5-watt/21-watt tail/brake light.

Convenient, water-resistant 12-volt DC power outlet handles a wide range of accessories.

Maintenance-free 18-amp-hour battery provides extra starting power, even in cold weather.

Underseat marine-spec electrical components ensure maximum protection from the elements.
