The STX-15F is the result of combining a high-revving, large-displacement 4-stroke engine and a compact, sporty-handling hull. Boasting a maximum output of more than 160 ps, the 4-cylinder, DOHC engine gives the STX-15F awesome performance.

Ninja Engine Technology
The 4-stroke, 4-cylinder engine is developed using Kawasaki Ninja motorcycle technology. DOHC, 16-valve, fuel-injected, in-line Four engine displaces 1,498 cc

Sophisticated ECU-controlled fuel injection system
Electronic fuel injection system delivers hard-hitting throttle response. Throttle body diameter of 60 mm ensures quick response and high power output at all rpm.

Water Jacketed Semi-Dry Exhaust System
Double-walled exhaust manifold helps reduce noise. Water surrounding the exhaust system lowers engine compartment temperatures for more power. The semi-dry exhaust system keeps cooling water out of the exhaust before the waterbox to prevent water from entering the engine if the boat should capsize. Dual waterboxes lower noise. Reduced emissions make this one of the cleanest watercraft around.

Kawasaki Smart Steering KSS
A steering sensor is linked to the ECU to aid in boat handling when the throttle is quickly released at high speed. This helps avoid possible collision especially for less experienced riders.

Kawasaki Smart Learing Operation
The smart learing operation (SLO) mode is designed to help new riders learn to operate a Kawasaki Jet Ski watercraft at a more relaxed pace. In SLO mode, engine RPM is electronically restricted by the ECU to restrict engine power and speed.

Plenty of Space
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 oarding 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.

Kawasaki Smart Steering / SLO-Mode
The Kawasaki Smart Steering (KSS) supplementary steering system is designed to assist new riders as they learn turning and manoeuvring of a personal watercraft. Experienced users may not even notice the system at all. Smart Learning Operation (SLO)-Mode function allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace before operating the Ultra LX at full power. Two separate keys (one for SLO-mode, one for full-power operation) prevent operating mistakes.

Lightweight Hull
Deep-V hull design enables a high bank angle, motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding. Measuring 22.5°, the idealised V-angle at the bottom of the hull helps prevent spin outs during sharp turns. As a result, the ULTRA LX delivers the neutral handling and turning characteristics for which Kawasaki JET SKI watercraft are famous.

Luxury Seating
The ULTRA LX is equipped with the LXuryseat, a scalloped seat designed for enhanced cruising comfort. Contoured for a good ergonomic fit, the LXuryseat offers ultra-comfortable accommodation for three. The seat’s steps can be compressed from above when sat upon, allowing riders to shift rearward during strong acceleration. In rough conditions, riders can sit on the steps, allowing the thick, impact-absorbing padding to do the work otherwise left to thigh muscles.

Marine 1,498 cc In-line Four Engine
Kicking out an impressive 160 PS at 7,500 rpm, the liquid-cooled, 1,498 cm3 In-line 4-cylinder Ninja supersport-based engine delivers the responsive performance that sport riders love. In spite of its high performance, this ultra-low emissions PWC easily clears the stringent CARB regulations. Engine strengthening items borrowed from the powerful ULTRA 300X ensure high durability and reliability.

Propulsion (Jet Pump / Impeller)
Developed based on feedback from Kawasaki’s race machines, this pump was specially designed to deliver incredible acceleration, stable output and good “bite,” even when riding in rough water. Using another trick borrowed from the ULTRA 300X engine, the jet pump drive shaft is supported using double bearings. A new shaft nut holds the shaft in place, preventing any forward movement. The result is increased reliability as well as greater durability.

Quattro KSD
Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull. The fourth splash deflector mounted at the top reduces spray during high-speed turns. Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimises spray, enhancing ride comfort.
