Introduction
The Pinnacle of JET SKI Performance
For true power addicts, nothing satisfies like a 260 horsepower
JET SKI®: A 1,498cc fuel-injected four-cylinder Kawasaki
powerplant provides plenty of thrust for most people, but the
engine in this special PWC is further fortified with the addition
of a Roots-type, crank-driven supercharger that compresses even
more air into those four cylinders to the tune of an incredible
260 horsepower(1). With that kind of power to manage, we gave
the Ultra® 260X the benefit of our 35-plus years of PWC experience,
including a race-refined high-performance hull and all the other
performance equipment you expect on a top-of-line Kawasaki JET
SKI. It's simple, really: This is the top of the PWC food chain.
Thanks to its Roots-type supercharger, the Ultra 260X is able
to produce power comparable to a normally aspirated high-performance
engine twice its size. Unlike centrifugal superchargers or turbochargers,
the high-volume, direct-drive, Roots-type supercharger force-feeds
the engine two liters of air with every revolution, providing
a stable supply of high-pressure air at all rpm from idle through
redline. This produces a smooth, linear torque curve that's perfect
for accelerating this Jet Ski watercraft hard, all the way from
a standstill through its breath-taking top-end.

conditions. Actual performance may vary.
With the 260X's supercharger compressing the air to a maximum
boost pressure of 11.4 psi, the intake charge can reach extremely
high temperatures potentially limiting the engine's power
output. The Ultra 260X nips that right in the bud, with a large-capacity
intercooler that brings the pressurized air back down to ambient
temperature or less ideal for maximum power production.
Utilizing lessons learned from Kawasaki's race machines, the
Ultra 260X's huge 155mm jet pump was designed to deliver predictable
thrust and good "traction" even in rough water. Its
sophisticated three-blade impeller delivers high performance
smoothly and quietly. The revised impeller design features blades
with less twist, to better convert the increased output from
the supercharged 1,498cc engine into blistering acceleration
performance.
A significant factor in this extra "traction" are the
pump's eight guide vanes that smooth the flow of water from the
impeller for efficient and powerful propulsion. The pump also
incorporates a groove from the center to the rear of the ride
plate, which makes it easier to hold a stable heading for straight-line
riding.
In addition to more power and acceleration than any other production
watercraft on the planet, the Ultra 260X also boasts a race-developed
hull. Its precise handling and superb stability are equally impressive,
thanks to a hull specifically designed to capitalize on the engine's
awesome performance. The fiberglass reinforced plastic (FRP)
hull is loaded with DNA from Kawasaki's IJSBA championship-winning
machines. This includes carefully designed sponsons and chines
for enhanced straight-line stability and more precise cornering,
combined with a 22.5° deep-V hull that leans into corners
like a motorcycle. This provides a smoother ride in rough water,
reduces the lateral G-loads generated during turns and helps
keep the rider in control.
The seaworthy hull design is just as comfortable in rough conditions
as in calm. Even at high speeds, rough water can do little to
deter the Ultra 260X. This combination of unearthly power mated
with the latest hull technology permits Kawasaki's flagship to
literally cleave through waves that would send lesser machines
running for a safe harbor.
The Ultra 260X features a five-step adjustable handlebar position
that allows either stand-up or sit-down riding for a wide range
of riders to enjoy the superior comfort and versatility. The
new Ultra 260X also includes thoughtful standard features like
an enormous 60-gallon storage space, including a detachable front
storage compartment and a 20.6-gallon fuel tank for substantial
cruising range.
From horsepower to handling and everything in between, once the
spray settles after the first ride, one thing will be certain.
The powerful Jet Ski Ultra 260X delivers a level of performance
and excitement unmatched by any other watercraft.
