2009 Kawasaki Jet Ski Ultra 260LX
THE ULTIMATE TOURING PWC
Watercraft riders seeking rock-steady stability, powerful acceleration and all-day comfort from a personal watercraft need look no further than the new JET SKI Ultra 260LX. Sharing the same supercharged 1,498cc DOHC in-line, four-cylinder engine and deep V-hull found in Kawasaki’s Ultra 260X performance flagship, the 260LX adds first class paintwork and a luxury touring seat to the stellar performance of the 260X. The relationship between these two Jet Ski watercraft is analogous to the relationship between Kawasaki’s mighty Ninja® ZX™-14 superbike and its supersport touring cousin, the Concours™ 14. The new Ultra 260LX features more performance than most pure-sport PWCs while offering long-distance comfort and utility like a Concours 14.
The Ultra 260LX’s comfort and handling features are enough to please any rider, but its Roots-type supercharger equipped 1,498cc engine gives it the accelerative performance to satisfy hard-core racers. The thrust from the race-tuned propulsion unit – also used on the Ultra 260X – is comparable to a normally aspirated high-performance engine of twice the displacement.
Unlike centrifugal superchargers or turbochargers, the high-volume, direct-drive, Roots-type supercharger force-feeds the engine two-liters of air with every revolution for a stable supply of high-pressure air at all rpm from idle to redline. This produces a smooth, linear torque curve that is ideal for accelerating a PWC all the way from a standstill through its breath-taking top-end speed.
With the 260LX’s supercharger compressing the air to a maximum boost pressure of 11.4psi, the intake charge can reach extremely-high temperatures – potentially limiting the engine’s power output. However, the Ultra 260LX uses a large-capacity intercooler to overcome this handicap, bringing the pressurized air in its intake back down to ambient temperature or even less – ideal for producing maximum power.
Utilizing lessons learned from Kawasaki’s race machines, the Ultra 260LX’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 new impeller design features blades with less twist, to better convert the increased output from the supercharged 1,498cc engine into blistering acceleration and enough top speed to thrill the entire family.
A significant factor in the pump’s extra “traction” are the 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 impressive power and acceleration, the Ultra 260LX also boasts a fiberglass reinforced plastic (FRP) hull loaded with DNA from Kawasaki’s IJSBA championship winning machines. Specifically designed to capitalize on the engine’s awesome power, this hull combines confidence-inspiring high-speed stability and excellent rough-water ride manners with responsive turning performance. Carefully designed sponsons and chines enhance the straight-line stability and precise cornering of the deep 22.5° V-angle hull.
Able to lean into corners like a motorcycle, the responsive, neutral handling hull helps to reduce the lateral G-loads generated during turns and helps keep the rider in control. The seaworthy hull design is just as comfortable and confidence-inspiring in rough conditions as in calm. Even at high speeds, rough water can do little to deter the smooth ride on the 260LX.
The Ultra 260LX is as easy-to-use as it is fast, luxurious and fun. It boasts a clever five-way adjustable steering handle to suit a variety of riding styles and rider sizes, making it possible to ride in either a standing or sitting position. Kawasaki’s innovative electronic Smart Learning Operation (SLO) mode can be selected to place a limit on maximum engine speed so novice riders can be offered reduced power levels and speed, while they master proper riding techniques. Its adjustable controls, SLO mode, and other family-friendly design features help make the Ultra 260LX more accessible to riders of varying size and ability.
The new luxury touring seat has a scalloped "saddle" shape for the rider, and a rise at the back for increased cruising comfort. The seat’s shape provides extra support for the rider and back passenger, and increases contact with the PWC and a more confident feeling connection with the seat. In rough conditions, riders can sit on the step, allowing the thick, impact-absorbing padding to do the work otherwise left to thigh muscles. The extra lower back support helps to reduce rider fatigue and will be especially appreciable in long no-wake zones or mid-speed riding on smooth water.
Nothing needs to be left behind with 53 gallons of built-in storage space, plus a detachable storage compartment that can hold even more. And the fun can keep on going, thanks to the large 20.6 gallon fuel tank, which gives the Ultra 260LX a substantial cruising range.
A velvet hammer, the Kawasaki Ultra 260LX delivers unparalleled performance and touring luxury on the water that allows riders to pursue family fun and their sense of adventure at the same time.
