Combining Kawasaki’s top-of-the-line, supercharged, 310 PS marine engine with the compact, sporty hull of the STX series has created the JET SKI STX 310, Kawasaki’s fastest-accelerating and most thrilling personal watercraft (PWC) ever.

Kawasaki’s innovative supercharged PWC technology has evolved since the introduction of the first supercharged model in 2007. The experience has been refined to culminate in a high-performing supercharged 1,498 cm3 4-stroke In-Line Four engine that gives the STX 310 the kind of thrills in straight-line acceleration that Kawasaki PWCs are famous for. Offered together for the first time, the supercharged engine and STX hull combination blends maximum power with sporty handling to deliver a unique riding experience.

Numerous creature comforts enhance the experience of the STX 310 RX and STX 310 R. Electronic cruise control reduces fatigue, a large TFT meter keeps riders informed, JETSOUND speakers and audio system add tunes to the mix (on the RX), a rear-view camera helps with docking and low-speed manoeuvres, plus multiple storage compartments provide ample space to stow gear. Sharp, sleek lines and LED accent lights contribute to a racing image, highlighting the performance potential of the compact package, while at the front, the Kawasaki River Mark visually signifies top-tier technology. 

With two models - the sport-focused R model and the RX model with its additional features - riders can choose their ideal JET SKI experience. From lake and waterway exploration to offshore excursions, the JET SKI STX 310 line delivers the quickest acceleration of any Kawasaki JET SKI two-person runabout ever for an intense waterborne experience. 

While performance is an instant stand-out there are many other features and rider aids that make the STX 310 series highly appealing. In terms of technology, standard features include launch control and power mode selection, electric trim control and electronic cruise control, plus Kawasaki Smart Reverse with Deceleration (KSRD). 

The large, easy-to-read 7-inch full-colour TFT instrumentation offers multiple display modes, jog-dial control, wireless connectivity and even infotainment features. A boost gauge adds to the excitement of the STX 310’s supercharged engine. 

Performance is matched by endurance thanks to a 78-litre fuel tank, while the rider’s smartphone can connect via the Powersports version of RIDEOLOGY THE APP, which offers the ability to keep track of friends during a ride, record and share trips, and monitor vehicle condition.

Every design detail of the JET SKI STX 310 models seamlessly comes together to create a striking, sporty appearance with a mix of dynamic lines and futuristic touches.

Eye-catching colours and graphics are enhanced by accent lights that further help these two exciting and high-performing supercharged STX 310 JET SKI models for 2027 stand out from the personal watercraft crowd.

For the coming season, a Three-Year Manufacturer Warranty covers the 2027 range plus all new machines in authorised Kawasaki dealer stock from 1 October 2026 onwards.
