Key Features: • Supercharged, intercooled 1,498cc engine puts out incredible power but is still designed for durability and reliability • Plush, scalloped luxury seat enhances comfort during high-speed cruising. Two-tone upholstery accentuates the functional bolsters for rider and passenger • GPS mounting area is built into handlebar pad for convenient placement of navigation devices • Stylish upper deck enhanced by rich metallic titanium color with luminous vintage red graphics • Massive, industry-leading storage capacity lets you bring your gear with you • Largest fuel tank in class keeps the fun going longer • Five-position adjustable handlebars accommodates a range of riders • Separate keys for full power operation and Smart Learning Operation
300-horsepower Supercharged Engine: • Supercharged and intercooled 1,498cc, liquid-cooled inline four-cylinder engine • Cast pistons with machine finishing for excellent durability • Stronger hardened nickel valves offer superior heat resistance and enhanced reliability • 33.4mm intake and 28.3mm exhaust valves • Two-layer oil cooler for efficient cooling • Reinforced crankcase adds to engine’s durability and reliability • Plastic intake manifold for weight savings • Optimum cylinder wall temperature is maintained by a check valve between the cylinder jacket and water muffler that shuts water flow off above 2,000 rpm, keeping the cooling water inside the cylinder jacket • Precise power adjustments are easy with a throttle lever designed to prevent finger fatigue on longer rides
Eaton Twin Vortices Series (TVS) Roots-type Supercharger: • Four-lobe design offers significant performance increase over standard roots-type unit • System force-feeds the engine two liters of air with every revolution, providing a stable supply of high-pressure intake air at all rpm • Delivers compressed air continuously, not in waves, for smoother power delivery • Produces large amounts of boost even at low rpm for instant and powerful acceleration right off idle • Provides a very flat and meaty torque curve with step-free power across the entire rev range without any of the lag associated with turbochargers • Produces more low rpm boost than competitive or aftermarket systems, with a maximum of 17 psi of boost pressure • Two different air bypass valves are used to prevent over boosting at low and medium rpm
Air-to-Water Intercooler: • Efficiently cools high-pressure intake air, as cooler air is denser and makes more power • Cooler air results in higher combustion efficiency and high engine output • Liquid cooling allows the intercooler to maintain consistent thermal performance
Digital Fuel Injection System: • High-flow fuel injectors with four orifices are fitted for combustion efficiency • Single throttle body per cylinder features a large, 60mm bore diameter
Exhaust: • 4-into-2-into-1 powerboat-style exhaust system routes the exhaust pipe upward • Allows the smoothest path for exhaust gases, maximizing exhaust efficiency
160mm Jet Propulsion• Efficiently converts the Ultra 300LX’s massive horsepower output into thrust using a 160mm-diameter jet pump • Developed from Kawasaki’s racing machines, this pump was specially designed to deliver stable output and good “bite” even when riding on rough water • Impeller features a 3-blade design that translates the 300X’s engine output into superb acceleration performance and quiet operation • An eight-vane intake guide is used to smooth and regulate the flow of water from the impeller for efficient and powerful propulsion • Left-side reverse lever offers easy operation
Ride Plate: • Features a groove from the center to the rear of the plate to enhance straight-line stability
Electronic Trim Control System: • Allows the angle of the jet pump nozzle to be controlled to adjust the attitude of the hull to suit water surface conditions and riding styles • Adjustment range is plus or minus 8 degrees from standard
Electronic Throttle Valve (ETV) with Cruise: • Accelerator Position Sensor (APS) converts throttle lever input to an electronic signal that’s used to control the throttle valve via an electric motor for optimum throttle response and smoothness • Redundancy in the system helps ensure control is maintained in case of failure • One-touch 5 mph mode allows push button no-wake zone riding • Fuel Economy Assistance mode allows maximum fuel efficiency when going slow • Economical Riding Indicator mode can be viewed on a graph on the LCD info screen • Cruise control smoothly holds the 300LX at a set speed from 5 mph up to top speed
Kawasaki Smart Steering®/SLO-Mode: • Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, raises rpm to help initiate a turn • Smart Learning Operation (SLO) allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace • Two separate keys, one for SLO mode and one for full-power operation, help prevent confusion over which setting is in use
