Kawasaki Ultra 300LX boasts the powerful
new 300hp variant of Kawasaki’s
1498cc engine. It has a
intercooler like the previous model, but Kawasaki has
replaced the supercharger design with an Eaton Twin Vortices
old supercharger produced surges of power. The new design
has twin counter-rotating lobes which deliver
the power in a steadier, continuous flow.
This, together with other modifications, results in
nearly 25 more pounds of torque, about 250 more pounds
of thrust, and a boost
pressure increase to 17.3 psi from the previous 11.
Jet Ski STX-15F personal watercraft provides
the precise handling and awe-inspiring acceleration
demanded by serious enthusiasts. It also provides
the comfort and convenience features for families
the highest quality three-passenger watercraft.
- With a high-performance four-stroke engine from the
legendary Kawasaki Ninja motorcycle line as its foundation,
the STX-15F delivers the kind of performance
expected from a Kawasaki jet ski watercraft. A smooth
spread of power across the entire rpm range thanks
the flat torque curve out of the long-stroke, 1,498cc
engine ensures plenty of good times. Dual overhead
cams, four valves per cylinder, fuel injection and
electronic engine control – to harmonize the
fuel and ignition systems – provide maximum performance
and reliability. A four-injector fuel injection system
combined with a large 60mm throttle body deliver a
as it is clean-running, the STX-15F’s four-stroke
engine is rubber-mounted in the hull, the performance-tuned
exhaust system is water-jacketed, and it has dual mufflers
and a large-capacity airbox.
STX-15F features Kawasaki’s innovative electronic
Smart Learning Operation (SLO). Accessible directly
on the instrument panel, SLO can be programmed to place
a limit on maximum engine speed so novice riders can
experience riding at a reduced speed as they master
proper riding techniques.
fitted to every STX-15F is the Kawasaki Smart Steering
(KSS). KSS features an on-board microprocessor that
is electronically linked to a steering sensor. When
the handlebar is fully turned in both direction and
the engine rpm drops from a designated rpm—as
when the throttle is released at speed—the microprocessor
activates the system, which raises engine rpm to provide
enough thrust to initiate the desired turn.
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 reboarding 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 space, an easily accessible glove box and additional
room for gear located under the seat.
features include a LCD instrument panel with fuel level,
speed, engine rpm, trip distance and time information
available. Fuel capacity is a generous 16.4 gallons,
for extended rides. Warning lamps alert the rider to
a low fuel level or high engine temperature, and a
magnetic keyed ignition switch helps deter unauthorized
