The Kawasaki Jet Ski STX-15F is a no-nonsense watercraft that offers a lot of value for its money. Featuring a composite hull, Kawasaki’s Smart Steering and a practical deck design, the Kawasaki Jet Ski STX-15F is ready to reward you with a unique experience every time you jump on its saddle.

The STX-15F is powered by a 1498 cc engine which is borrowed directly from the sporty Ninja ZX-14R sportbike. The engine features dual overhead cams, four valves per cylinder, fuel injection and an electronic control unit. Needles to say, it delivers a generous low- and mid-range torque and cranks out a maximum power of 160 horsepower.

The Kawasaki Jet Ski STX-15F also features modern digital instrumentation which includes a speedometer, tachometer and fuel gauge.

The Jet Ski is priced at $9,699.

Performance Bargain Watercraft Has The Heart of A Ninja®

New Kawasaki flagship watercraft often boast tremendous performance and state-of-the-art features, while other models offer a lot of bang for the buck if you’re willing to compromise on some of the bells and whistles. The Kawasaki JET SKI® STX®-15F is one watercraft that doesn’t compromise performance for value. With a powerful four-stroke engine, a sporty-handling composite hull and plenty of rider-friendly features, the STX-15F is sure to be the bargain of the summer for enthusiasts seeking fun on the water.

The STX-15F proudly carries the heart of a Ninja®. Derived from Kawasaki’s class-leading Ninja® ZX™-14R sportbike, its 1,498cc engine delivers plenty of low- and mid-range torque while generating an impressive 160 horsepower . But this engine blends snappy performance with excellent fuel economy and low emissions. In fact, the STX-15F has earned a Three-Star Ultra-Low Emissions rating from the California Air Resources Board, and it meets the Environmental Protection Agency’s strictest standards.

Dual overhead cams, four valves per cylinder, fuel injection and electronic control unit (ECU) – to harmonize the fuel and ignition systems – provide maximum performance and reliability. A four-injector fuel injection system combined with a large 60mm throttle body delivers a quick response. The STX-15F’s four-stroke engine is rubber mounted, and features a performance-tuned exhaust and large-capacity airbox.

Propulsion duties are handled by a direct drive axial-flow jet pump driving an oval-edge, stainless steel, three-blade 148mm impeller for powerful acceleration. Tuned to produce its peak power at a relatively low rpm, the STX-15F engine matches the impeller’s peak efficiency to provide rider-friendly propelling performance. This direct drive arrangement eliminates any need for a complex gear reduction unit and offers improved durability and increased fuel economy with less vibration and noise.

The STX-15F personal watercraft features Kawasaki’s innovative electronic Smart Learning Operation (SLO). Accessible directly on the instrument panel, SLO can be programmed to limit maximum engine speed so novices can experience riding at a reduced speed as they master proper techniques.

Aggressive turning and high-speed tracking are key performance attributes of the STX-15F. Its specifically designed injection-molded sponsons have a special “lip” for increased cornering grip and high-speed tracking. The STX-15F personal watercraft also gets electronic turning help via its Kawasaki Smart Steering® (KSS®) system. KSS features an on-board microprocessor that is electronically linked to a steering sensor. When the handlebar is fully turned in either direction and the engine rpm drops from a designated rpm – as when the throttle is released at speed – the microprocessor activates the system, which raises engine rpm to provide thrust for maneuvering.

Additionally, a molded-in Kawasaki Splash Deflector (KSD) is incorporated into the hull design to help minimize spray on the rider. This muscular and aggressive looking STX-15F may be lighter and more compact than the competition, but its spacious riding position makes aggressive performance riding easier while suiting a wider range of riders.

The spacious rear deck of the STX-15F makes it easy to get into water skis or on a wakeboard. An automatically retracting boarding step located on the rear of the hull simplifies boarding in deep water. There is no shortage of space to stow items on the STX-15F. The rear deck can accommodate items needed for a day on the water, like a cooler, along with a water-resistant storage compartment, an easily accessible glove box and additional room for gear located under the seat.

Like the rest of the high-quality styling of the STX-15F, the hatch cover is sleek ABS plastic and uses a hydraulic damper to hold it open, allowing easy access until the rider closes it. Also made of ABS plastic, the mirrors echo the sleek lines and are mounted directly to the deck.

With a generous 16.4-gallon fuel capacity allowing for extended rides, there is plenty of time to enjoy the cockpit features. These include a LCD instrument panel with fuel level, speed, engine rpm, trip distance and time information available and warning lamps to alert the rider of a low fuel level or high engine temperature, along with a magnetic keyed ignition switch that helps deter unauthorized operation.
