Engine
- Strong, 1,498cc, four-stroke engine provides excellent low- and
mid-range torque
- Dual overhead cams (DOHC) are light and compact for less valve train
inertial mass
- Four, large valves per cylinder provide better intake and exhaust flow
for optimum torque and power
- Intake and exhaust valve lift as well as timing are set to reduce
exhaust emissions
- Intake tract designed for maximum performance
- Waterproof ECU and ignition coils protects the ignition system from
electrical shorts
- Unique semi-dry sump oil system lowers the crankshaft in the engine,
eliminates the need for scavenging pumps, and keeps the oil in the sump
instead of flooding the crankcase if the craft is capsized
- Large capacity airbox lowers engine noise and improves air intake flow
Fuel Injection
- Single throttle body features a large 60mm bore diameter
- Digital fuel injection provides great throttle response, smooth engine
performance and quick acceleration, as well as easy starting and
excellent fuel economy
- High-flow fuel injectors with four orifices are fitted to complement
the increased power output and improve combustion efficiency
Propulsion
- Large-diameter 155mm jet pump efficiently converts the engine’s
horsepower into thrust
- Developed based on feedback from Kawasaki’s race machines, this pump
is designed to deliver stable output and good “bite,” even when riding
on rough water
- The reverse lever on the left side for easy operation
- The large, sophisticated three-blade impeller unit delivers both high
speed performance and quiet operation
- Eight-vane intake guide smoothes and regulates the flow of water from
the impeller for efficient and powerful propulsion
Ride Plate
- Features a groove from the center to the rear of the ride plate, to
enhance straight-line stability
Hull
- Designed integrates feedback from Kawasaki’s IJSBA championship
winning racing machines, the hull offers high stability and responsive
handling in both calm and rough-water conditions
- Delivers the neutral handling and turning characteristics that made
Kawasaki JET SKI personal watercraft famous, yet the hull enables a high
bank angle, for motorcycle-like turning performance with reduced side
G-loads imposed on riders during turns
- The 22.5° V-angle at the bottom of the Ultra LX’s hull helps prevent
spinouts during sharp turns and to provide a smoother ride in rough
water
- Placing the battery is inside the front storage area, near the center
of the machine, provide better weight balance in the hull and frees up
space inside the engine bay
- Bottom of the hull slants upwards steeply from the center section to
the bow, allowing the Ultra LX to penetrate swells and waves with less
shock. At low speeds, this provides extreme stability while at a higher
pace the hull can push through waves rather than bounce over them
- Integrated sponsons extend from the hull, providing stable wallow-free
straight-line performance and contributing significantly to the Ultra
LX’s excellent high speed maneuverability while helping to retain the
narrow hull design
Quattro KSD
- The Ultra LX’s Kawasaki Splash Deflector uses three bottom mounted
ridges and an additional deflector mounted at the top to deflect water
splashing forward from under the hull
- Whether turning or blasting straight ahead, at high speeds or low, the
Quattro KSD minimize spray, allowing greater rider concentration
Kawasaki Smart Steering®/SLO-Mode
- Kawasaki Smart Steering® (KSS®) monitors steering input and engine
speed and, when certain conditions are met, raises rpm to initiate a
desired turn, helping new riders better enjoy the performance of this
remarkable machine
- Smart Learning Operation (SLO) allows newer riders to become familiar
with the handling and response of this JET SKI watercraft at a more
relaxed pace before unleashing the full performance of the Ultra LX
- Two separate keys, one for SLO-mode and one for full-power operation
help prevent confusion over which setting is in use
Comfort and Convenience
- Five-way adjustable handlebars allow operation while standing or
sitting for a wide range of riders
- Relatively narrow seat is comfortable for riding stand-up or seated,
as well as for the passengers
- Ergonomic deck design gives plenty of legroom for rider-friendly
seating accommodations
- A long rear boarding step makes it easy to climb onboard, and the step
retracts inside the bumper to prevent damage
- A quick and easy under hood hose connection allows easy flushing of
sea water out of the engine
- Mirrors mounted on the upper deck facilitate opening of the hatch
cover
Capacious Storage
- The large-capacity, fully sealed 53 gallon storage area with a
detachable storage tray fitted has plenty of room for recreational
equipment
- On the center console is a detachable drink holder with space for two
drink bottles
- Ideal for small items is a compact storage area with the under-seat
rear grip
