Kawasaki Motor Corp.Kawasaki is replacing its MULE™ 550 off-road utility vehicle with two all-new, leading-edge compact models that will be popular for both work and recreation. The MULE 610 4x4 – which is the first four-wheel drive utility vehicle in its class – and its two-wheel drive counterpart, the MULE 600, produce more power and accelerate more authoritatively than their predecessor, and feature all-new, rugged styling. And true to form, both of these compact Kawasaki utility vehicles can fit in the bed of a full-sized pickup truck.

The models feature a new single-cylinder engine that is matched to an improved continuously variable transmission, dual-mode differential, independent front suspension, swing-frame rear suspension and sealed hydraulic brakes.

The most visible difference between the new 600 series and the out-going 550 is the styling. By lengthening the chassis nearly four inches, designers were able to create a more spacious cab for the MULE 610 4x4 and MULE 600. The curved body panels, redesigned bonnet and grille, and large-diameter steel tube frame give them a clean, modern look, while automotive-type controls and gear selectors are now located on the newly styled dashboard. Luxury features include two large cup holders, a passengerside glove box and a passenger-side grab handle.

Other highlights include a 48-liter storage space located beneath the bonnet, more storage space under the bench seat, and a winch mount located behind the grille. For many utility vehicle owners, the larger engine is the most enticing feature of the new MULE 610 4x4 and MULE 600. The air-cooled, single-cylinder four-stroke engine displaces 401cc and accelerates with more authority than its 286cc predecessor, and it includes a cooling fan to help it maintain an ideal operating temperature. Equally important, the new engine is easier to start due to a new enrichening system that opens the throttle nearly 20 percent during starting, thereby eliminating the need to apply the throttle. Both models feature a 25 mph maximum speed governor.

To maximize the four-wheel drive capability of the MULE 610 4x4, its engine includes performance enhancements such as reshaped intake and exhaust ports increased valve lift, larger exhaust valves and a higher compression ratio.

Both models transfer their power through a continuously variable transmission (CVT), which features more durable materials in the converter and a longer-lasting drive belt to match the engine’s enhanced acceleration and hill-climbing performance. With its high and low range forward gears, plus reverse, the sturdy transmission can also be started in any gear, provided the brakes are applied.

Both MULE 600 models utilize dependable, low-maintenance shaft drive and feature a dual-mode differential that can be locked to maximize traction on adverse terrain. The MULE 610 4x4, however, includes selectable four-wheel drive and includes a limited-slip front differential.

The MULE 600s ride on MacPherson strut front suspension, while rear suspension duties are handled by a swing-frame rear suspension. Triple-sealed hydraulic drum brakes at all four wheels provide ample stopping power and both models ride on large 24-inch tires for improved off-road handling. Also, a plastic front differential/axle guard and steel rear differential guard are standard on both models, helping to protect these important powertrain components.

To light the way on dark evenings, the MULE 600s feature the same gourd-style, quadruple 40-watt headlights as the new Kawasaki BRUTE FORCE™ 750 4x4i all-terrain vehicle. Kawasaki engineers know that hauling and towing are the two most-common tasks for any MULE utility vehicle, so they designed the MULE 610 4x4 and MULE 600 to carry 400 pounds in their tilting cargo beds. They also feature new tailgate latches that are easy to fasten quickly and securely. Plus, either model can tow up to 1,100 pounds with an optional towing hitch – 200 pounds more than the previous model. A host of accessories are available for the MULE 610 4x4 and MULE 600, including headlight guards, a hard top for the cab, windshield and various under guards for both two- and four-wheel drive models. These Authentic Kawasaki Accessories are available through Kawasaki dealers or they can be purchased on the Internet at
