The Jet Ski STX160 features new JetSki styling for 2020, improving looks, comfort, and Jet Ski performance. The hull height has been raised and the rear portion of the Jet Ski bumper has been extended. The styling emphasizes flowing lines and spacious feel, while also blending styling cues from the Kawasaki ULTRA series such as the nose grill, all of which helps to create a distinctive style that makes it immediately recognizable as an Kawasaki STX watercraft PWC. The handle area now features a lighter and sharper design by reducing the size of the Jet Ski pad and using colored Jet Ski parts. The bumper is a three-dimensional shape with clean defined edges that blends well with the dynamic feel of the hull. Increased field of vision of the rearward mirror was achieved by widening the viewing angle of the exterior of the lens to a shape that matches the overall design, while significantly reducing the weight. Improved sound comes by way of a new speaker box on the Kawasaki LX model, which provides Jet riders with a clear audio. The shape of the box has been changed to match the image of the hull. The area of the rear platform has been expanded through an extension of the rear pan bar. The Kawasaki LX model is equipped with a two-color tone dedicated Jet Ski deck mat.
Increased comfort was achieved by creating a relaxed Jet Ski riding position, with generous room for Jet Ski riders to bend their knees. When combined with a newly designed Jet Ski seat, Jet Ski cruising and Jet Ski touring are more comfortable than ever before.
The new bodywork efficiently secures space and expands the fuel tank capacity from 16.4 gal to 20.6 gal, giving it the largest capacity in its class. Combined with Jet Ski engine characteristics that allow for excellent Jet Ski fuel efficiency, touring ability is enhanced.
The bodywork was revamped to expand the Jet Ski engine room space. Combined with the use of slide and lift Jet Ski seats, Jet Ski battery access is easy, making tasks from daily inspections to Jet Ski maintenance more efficient.
The reverse lever has been moved to the left side, making it possible to operate the Jet Ski throttle with the right hand and the reverse with the left hand.
A slide and Jet Ski lift system is used to open the rear Jet Ski seat. This allows access to under-seat storage and Jet Ski flush ports without the need to remove the rear Jet Ski seat. The Kawasaki Jet Ski STX160 features an improved Jet Ski step to make re-boarding easier when wakeboarding and swimming. The rear Jet Ski grip has two grip sections for convenient re-boarding.
Jet Ski Engine
The Kawasaki Jet Ski STX160 personal watercraft PWC is powered by a 1498cc DOHC, 16-valve, parallel 4-cylinder, fuel-injected Jet Ski engine. The bore and stroke of the Jet Ski engine are 83 × 69.2 mm, with a compression ratio of 10.6: 1. Pairing a large diameter 60 mm throttle body with an electronic fuel injection system ensures quick, strong power throughout the rpm range. The intake valve diameter measure sizes measure 33.4 mm, while the Jet Ski exhaust valve diameter sizes measure 28.3 mm. A narrow valve angle (Intake at 12 degrees, Exhaust at 13 degrees) allows for an efficient combustion chamber shape. The electroplated all-aluminum Jet Ski cylinders are lightweight, highly durable, and provide excellent heat dissipation. Corrosion-resistant valves were chosen to ensure high reliability that helps to conserve the marine environment. Inwardly tapered Jet Ski piston pins were chosen to reduce the reciprocating weight inertia of the Jet Ski piston.
The front Jet Ski cam drive enables efficient Jetski engine intake with a narrow valve angle. Because there is a drive at the front end of the Jet Ski crank, the short, highly rigid Jet Ski crank exhibits high torsional rigidity. The forged Jet Ski crank is supported by five plain bearings and reduces friction loss with a small bearing journal. The silent jet Ski cam chain reduces mechanical noise. A digital transistor Jet Ski ignition with a timing sensor is installed at the front end of the Jet Ski crankshaft, and it is equipped with an Jet Ski engine speed limiter and K-TRIC (TPS) sensor. The generator and power output are located at the rear of the Jetski crank while the Jet Ski camshaft and Jet Ski oil pump drive are located at the front.
A liquid-cooled Jet Ski exhaust manifold with a double wall structure is used for efficient cooling. Two Jet Ski water boxes contribute to reducing Jet Ski exhaust noise and cooling water is pumped from a JetSki jet pump. In order to prevent foreign objects from entering the system, a Jet Ski filter is installed at the entrance.
The high-speed Kawasaki jet pump of the Jet Ski STX160 achieves excellent maximum speed and acceleration. It uses an oval-edged three-blade cast Kawasaki stainless steel impeller for powerful acceleration, high thrust efficiency, and low cavitation. Its sturdy stainless-steel blades are less susceptible to damage and help prevent cavitation erosion. The Kawasaki jet pump Jet Ski driveline is equipped with a large rubber coupling to absorb impact loads from powerful Jet Ski engines and reduce Jet Ski driveline noise. The robust drive shaft transfers Jet Ski engine power stably and efficiently. A sealed bearing supports the Jet Ski drive shaft. The cast aluminum steering nozzle efficiently transmits the large Jet Ski engine thrust.
The Kawasaki Jet Ski STX160 utilizes an accelerator position sensor in the jet Ski throttle lever section, helping to reduce operating load. Using the accelerator Jet Ski lever along with cruise control can reduce the hand fatigue associated with long Jet Ski rides.
The Jet Ski rider can set the Jet Ski engine speed at will using the electronic cruise control and support will be provided for comfortable Jet Ski cruising. On the X and LX models, the Jet Ski speed can be adjusted after being set with the UP/DOWN buttons that are within arm’s reach.
Another convenient feature found on the Kawasaki Jet Ski STX160 is the one-touch 5 mph mode. This mode is convenient in places where you must avoid causing wake, such as in a marina or bay. Jet Ski Riders can maintain their Jet Ski speed at 5 mph with a single touch.
The Kawasaki Smart Steering® system uses sensors to detect the Jet Ski engine speed, Jetski steering status, and JetSki throttle opening angle. When the operating conditions are met, it maintains the JetSki engine speed necessary for turning and generates propulsion. Even if the JetSki throttle is fully closed, it functions when the JetSki throttle is suddenly fully closed due to high speeds and does not operate when continuously going at low-speed, such as when docking.
The Kawasaki Jet Ski STX160 can be operated in Smart Learning Operation (SLO) Mode, a function that can keeps the engine output lower than usual. This allows new Jetski riders to become familiar with the Jet Ski watercraft. Jet Riders can also make sure they are using fuel efficiency with the Economical JetSki Riding Indicator “ECO” symbol on the meter, which lights up when the system determines that Jet ski fuel consumption efficiency is excellent.
The Jet Ski STX160 features a system that can clean the JetSki engine-cooling path with the JetSki engine room closed to help reduce the noise during Jet Ski maintenance.
The Jet Ski STX160 is equipped with an immobilizer function, which helps to deter theft.
Jet ski Hull
The Jet Ski hull of the Jet Ski STX160 is made from fiber-reinforced plastic (FRP) that produces a light and robust Jet Ski body, which also features an integrated floating cell structure. It also has a high-performance keel line to improve maneuverability and Jet Ski rider control. A sturdy Jet Ski bumper that extends around the entire circumference protects the Jet Ski hull. The large rear platform facilitates re-boarding and allows Jet Ski riders to carry long items such as wakeboards with ease. The automatic siphon Jet Ski bilge system supports water discharge from the JetSki engine room during use. The Kawasaki Triple Splash Deflector minimizes the water that splashes on the Jet Ski rider during cruising, allowing for a comfortable Jet ski riding experience. The Jet Ski Sponson fins are installed at the bottom of the bumper that covers the hull surroundings, which improve straight-line stability.
Jet Ski Equipment
The Jet Ski STX160 LX personal watercraft includes the JETSOUND® integrated Jet Ski audio system feature with Bluetooth as standard equipment, and it is available as a Kawasaki Genuine Accessory on the other models. The system consists of an amplifier, an Jet Ski audio controller built into the handle, and two Jet Ski speakers placed under the mirrors. The amplifier is 40 W x 4 channels, 160 W maximum. The speaker ratings are 30 W each. Maximum 60 W x 2. The system is connectable via Bluetooth, USB, and AUX, the USB and AUX ports are installed in the waterproof storage and the controls provided by the audio controller depend on the connection method.
The Jet Ski STX160 is equipped with a large digital meter that uses an LCD display with excellent visibility. A speedometer with a bar graph-type Jet Ski tachometer is located in the center. It displays various information such as a fuel gauge and instantaneous Jet Ski fuel consumption, an hour meter, an outboard water temperature meter, an external temperature meter, maximum speed history, and economic Jet Ski riding indicator. The position of the instrument panel and the design of the cockpit visor ensure excellent visibility.
The Jet Ski STX160 LX model features a luxury Jet Ski seat designed to fit the Jet Ski rider’s body ergonomically to further improve comfort. Both the Jet Ski STX160 X and LX models feature a new gun-grip handle Jet Ski grip that tapers outward, making it easier to hold when Jet ski riding in a straight line.
The new hull of the Jet Ski STX160 has increased storage capacity compared to previous model; there is 30.1 gal available for front storage, and 4.4 gal for rear Jet Ski seat storage available. The central storage has a small waterproof compartment and is suitable for storing smartphones. The rear of the hull is equipped with an easy-access rear pocket that is convenient for storing wet Jet Ski towing ropes. Another welcomed addition to the hull is Two Cup holders have been newly installed toward the back of the handle.
