Class-Leading Performance
Fitted with a supercharger and intercooler, the liquid-cooled 1,498 cc, In-Line 4-cylinder marine engine propels the Ultra 310 Series models forward with an exhilarating rush of acceleration.
Experience the thrill of one of the most powerful supercharged personal watercrafts in the PWC industry. The Jet Ski Ultra 310 series represents the modern generation of the most iconic name in watersports. This flagship platform features premium, class-leading features from nose to tail, including creature comforts for all-day fun on the water.
Experience the Exhilaration
With a supercharged engine recognised as one of the most powerful in the PWC industry and a race-developed hull acclaimed for its handling and precision in both calm and rough water, Ultra 310 Series models deliver an unmatched level of performance and excitement.
Superb Calm- & Rough-Water Handling
Loaded with technology from Kawasaki’s championship-winning machines, the race-developed hull handles with precision and control, with a high level of seaworthiness – and at speeds from idle to its impressive top end.
Automatic Trim Adjustment
When accelerating with the system engaged, the trim is automatically optimised. Two modes allow either single or repeated launches.
Enhanced Power Management
Riders can select from Full, Middle and Low Power Operation, as well as Smart Learning Operation (SLO)-Mode.
Increased Comfort & Convenience
Befitting Kawasaki’s flagship Jet Ski models, a host of new equipment and features offer significantly increased comfort and convenience.
Slim Design
Two-piece, three-person seat offers roomy accommodation for three people. Its redesigned front portion is 80 mm slimmer at the knees, greatly facilitating stand-up riding.
Spacious Layout
The deck is flatter and 35 mm lower at the rider’s feet, offering more leg room for increased comfort.
KSRD (Kawasaki Smart Reverse with Deceleration)
Kawasaki Smart Reverse with Deceleration electrically deploys the reverse bucket. Activated with a thumb switch on the right handle, it enables thrust to be controlled with one hand. When fully deployed, the reverse bucket contributes to deceleration.
7" TFT Display
Large, easy-to-read 7” full-colour TFT instrumentation offers multiple display modes, jog-dial control, Bluetooth connectivity, and even infotainment features.
Functional Storage
Completely rethought storage system offers a total storage capacity of 168.5 litres. The 124-litre sealed front compartment is complemented by the new 40-litre Easy-Access Storage (behind the handle, accessible from either the left or the right), a 1.7-litre waterproof compartment (inside the Easy-Access Storage), and 2.8-litre Easy-Access Rear Pocket (aft of the rear seat).
Easy-Access Cleats
Built-in cleats (one on each side) provide convenient cinch points when mooring at a dock. Their clever design helps redirect water overboard.
Numerous Industry Firsts
The Ultra 310LX-S and 310LX boast even more new equipment and features. Along with the Easy-Access Storage, the rearview camera and four-speaker audio system are PWC World firsts.
Broader staging platform
200 mm longer than the standard rear deck, the extended Ultra deck offers a broader staging platform for water play, and more room for stowing gear. The Multi-Mount Rails built into the deck accommodate accessory slide mounts to provide convenient tie-down points.
Rearview Camera
Rearview camera mounted aft of the rear seat offers riders a supplemental rearward view behind the Jet Ski. The camera can be monitored via the instrument panel, and is convenient when towing a waterskier or wakeboarder, or when docking.
3-Position ERGO-FIT LXury Seat
The Ultra 310LX is equipped with Kawasaki’s first adjustable PWC seat. The ERGO-FIT LXury Seat, a contoured seat designed for enhanced cruising comfort offers ultra-comfortable accommodation for three. Its pin-style mounting system offers three positions spanning 70 mm – each 35 mm apart. Completely redesigned, with a new shape and revised urethane, the two-piece seat is slimmer at the knees (like the standard seat), and provides deeper hip support for all three occupants. Wadding (first use on a Jet Ski model) contributes the seat’s high-quality, luxurious feel.
PWC Industry's First Standard-Equipment 4-Speaker Audio System
An improved version of Kawasaki’s original PWC audio system, JETSOUND 4s features four speakers, jog-dial control and Bluetooth connectivity.
Dynamism, 3D Feel and High Attention to Detail
All-new from the deck up, the 2022 Ultra 310 Series models were completely restyled to give them a fresh image. Their “dynamic luxury” design maintains the dynamism of their predecessors while adding a three-dimension feel, and a high attention to detail ensures a luxurious, high-grade finish for each of the three distinctive, head-turning designs.
3D Deck Design
Designers carefully crafted parts with a three-dimensional feel to complement the dynamic styling, expertly weaving these pieces together to create a high-grade, bespoke design.
