Engine
* Water-cooled, 891 cm3 2-stroke Triple pumps out impressive power across the rev range.
* Durable cast-iron liner sleeves are inserted during the casting process (not press fit afterwards) of the cast-aluminium cylinder block for increased structural integrity of the entire cylinder block.
* Crankcase reed induction system for high intake efficiency.
* Efficient three-into-one exhaust manifold utilises optimal exhaust-pulse effect for incredibly strong low-speed torque output and an awesome top-end power curve.
* Intake duct elongates each cylinder's intake passage for excellent throttle response during low-speed cruising.
* Water jackets encase the exhaust pipe, exhaust manifold and the circumference of the exhaust chamber, to reduce engine noise and lower the temperature of aluminium components for increased durability.
* When air temperature inside the hull climbs too high, the igniter compensates by advancing ignition timing to avoid power fade.
* Most aluminium-alloy engine parts are clear-coated after painting for maximum corrosion resistance.
Propulsion
* Oval-edge, 3-blade, cast stainless steel impeller refined to match engine and hull for high efficiency and low cavitation. Tough cast-stainless steel airfoil is less likely to suffer damage, helping to prevent cavitation erosion.
* The incredibly versatile hull, jet pump design and rear ride plate mean the 900 STX can accelerate quickly and reach planing speed very easily.
* Axial-flow pump for efficient propulsion.
* Special vanes on the pump inlet smooth the flow of intake water to the high-performance impeller.
Hull
* Rugged deep-V hull with deep forward section and strakes for reduced wave shock and superb handling performance over a wide range of riding conditions.
* Triple Kawasaki Splash Deflector (KSD): A lateral strip on the forward section of the hull dramatically reduces water splash, especially at speed and in rough water. The 900 STX offers one of the driest, most comfortable rides on the water.
* Sleek keel line reduces friction while enhancing manoeuvrability and rider control.
* Front inlet shape optimises water inflow. Rear of water inlet is smoother for reduced resistance.
* Extended spray strip facilitates rear-end grip and bow lift.
* Sponsons on the outer rear edge of the hull ensure optimum planing and add to cornering performance, enabling the craft to hook up and turn smoothly.
* Aerodynamic form follows the canopy line of the Ultra 150, combining a stylish bodyline. made from Sheet Moulding Compound (SMC) for toughness and durability.
* Hand-laid FRP hull features a durable high-gloss gel coat for extra strength and rigidity.
Other
* Extra-large, watertight storage compartment (72.2 litre capacity) in the front of the hull.
* Compartments (2.6 litre capacity) provided fore and aft of the seat for stowing small items.
* Large, 14.2 litre capacity compartment under rear seat is easily accessible.
* Hydraulic shock absorber system for hatch cover stopper for smooth opening and closing.
* Cargo net hook in the rear of the seat is made of lightweight aluminium, and together with the open rear deck, a variety of loading options are available.
* Extra-large after-deck for easy deep-water boarding and carrying larger items.
* A retracting rear boarding step makes deep-water boarding a snap.
* Convenient towing hook.
* 53 litre capacity fuel tank gives long-range touring capability.
* Recessed bow eye for easy towing.
* Twin adjustable rear-view mirrors.
* Comfortable two-piece separable seat complements the overall design and uses urethane material for extended riding comfort.
* Easy-to-read extra-large digital display. Instrumentation includes speedometer, fuel level and oil level gauges, a digital clock that measures time, hours elapsed and total running time.
* Oil and temperature warning light warns rider of low oil level and excessive engine temperature.
* Magnetic, theft-deterrent main ignition switch helps prevent unauthorised use.
* Wrist lanyard connected to the engine stop switch automatically stops the engine should the operator fall overboard.
