ERGONOMICS
Ultra 310R’s ergonomic appointments not only enhance its aggressive, racy looks, but they’re designed for hardcore sport riding and comfort to boot. Borrowing a cue from Kawasaki’s championship-winning KX™ line of motocross motorcycles, the Ultra 310R features a solid motocross-style handlebar complete with a crossbar pad for hard sport riding. The electro-polished stainless steel bartransfers direct rider inputs and offers tremendous leverage for easy maneuverability. It is also comfortable for longer rides. The handlebar mounts are adjustable to 12 different height/reach combinations, and can be rotated to provide up to 16 options. This means it can fit a wide range of riders and riding styles, with Kawasaki Genuine Accessories’ clamps giving even more adjustment.
A two-piece sportseat with KX motocross-style seat material and graphics offers roomy accommodations for a rider plus two passengers. The seat design features a slim shape for more comfort around the thighs plusgood hip support.Its narrow width makes it easy to grip with the knees when standing up to ride rough water. The passenger portion of the seat also features a slim design that makes it easy for passengers to hold with their legs in rough water conditions. The passenger handrail is positioned high to offer a more natural,ergonomic location, which helps reduce passenger fatigue,beingshaped for better holding power. 

POWERTRAIN
With 310 horsepower the supercharged inline four-cylinder engine is the most powerful production powerplanton the market,and the basis for an open-water, race-winningengine.With the extraordinary handling and an impressive collection of performance-enhancing qualities, the Jet Ski® Ultra® 310R leaves the competition floundering in its wake. Performance watercraft enthusiasts seeking a healthy dose of aquatic fun need look no farther than the Ultra 310R. 
The Ultra 310R’s Digital Fuel Injection-fed (DFI®) 1,498cc engine is the reigning king of horsepower, and its crown isthe high-tech Eaton TVS series supercharger. The superchargergives the engine exhilarating yet linear power, and its race-derived hull design makes short work of carving precise turns in calm or rough water, exactly what hard-core performance enthusiasts would expect from a sport-oriented Kawasaki Jet Ski. 
The Ultra 310R benefits from many key components being incorporated into the design and build of this machine. For instance, the 310R’s intake manifold is shaped to have a long and slim profile that increases low-mid range power. A fuel pump with superior flow volume adds power and increases fuel efficiency, and the Fuel Economy Assistance mode in the Electronic Control Unit (ECU) is specifically tuned to increase range for long-distance riding. 
Kawasaki Jet Ski watercraft are the gold standard in quality and reliability, and Kawasaki engineers are relentless in their pursuit to take those attributes to higher levels. The 310R has cast pistons with a V-groove at second ring land (between the top and second ring grooves) for more consistent oil retention at high loads. To aid piston cooling, the oil jet system that sprays the underside of the piston includes two jets per piston, rather than just one, for better performance. Baffles in the oil pan prevent oil from accumulating on one side of the pan during tight turns or sudden acceleration or deceleration, and the crankcase also has large return holes to facilitate oil return to the pan. Superior oil management equals increased reliability. 
The water jackets in the engine are thick for optimum cooling performance, and they utilize a check-valve that opens when the engine is idling or stopped, but closes when it is running to keep the engine cool without over-cooling. The 310R also includes a knock sensor that facilitates engine protection by retarding ignition to suppress abnormal combustion – or engine knock – if it should occur. The system activates a buzzer and the condition is indicated on the instrument panel to warn the rider. 
But eye-watering thrust is still the main attraction with the Ultra 310R, and its fuel-injected, DOHC, inline four-cylinder engine pumps out pulse-quickening performance like no other PWC powerplant on earth! Its roots-type Eaton Twin Vortices Series (TVS) supercharger’s efficiency lies in its design, with a pair of four-lobe rotors boosting engine output.The TVS is a fixed-displacement design, which means it produces large quantities of boost at all RPM, from idle to redline. It gives the 310R a flat torque curve and linear power across the rev range that no other production watercraft turbocharger or supercharger system can match. 
Ultra 310R’s smooth power delivery is due to its ability to channel compressed air through the engine at a steady rate, instead of in waves, as other superchargers do. And its liquid-cooled intercooler helps to cool the compressed intake charge as it enters the Ultra 310R’s combustion chambers. Cooler air equals denser air, which means less power is lost to performance-robbing engine heat.
Ultimate performance is worthless without rock-solid reliability, and the 310R engine was built from the bottom to top for long-lasting durability in a supercharged application. Its internal engine parts are manufactured to a level of Kawasaki Jet Ski reliability that is unparalleled in the PWC industry. A perfect example of Kawasaki’s attention to detail lies in the ultra 310R’s super-efficient oil cooler, which helps minimize engine temperatures by circulating oil between two cooling jackets. The result is 310 class-leading and stone-reliable horsepower. 

ELECTRONICS
An impressive collection of futuristic electronics is standard on the Ultra 310R. Naturally, Kawasaki’s high-tech Electronic Control Unit (ECU) is the command center of the entire system.The ECU coordinates the injectors and throttle bodies of Kawasaki’s highly advanced DFI to route the optimum amount of air/fuel mixture into the combustion chambers with help from the Electronic Throttle Valve (ETV) system, which converts throttle lever inputs into electronic signals that are then passed on to the throttle body. 
Ultra 310R’s technological arsenal hasa number of superior rider aidsthat include the Fuel Economy Assist mode for maximum economy, which switches the ECU to a fuel map that focuses on gas mileage. There is also a one-touch 5mph mode for no-wake zones and a convenient Electronic Cruise Control system to set a steady cruising speed when touring. The Smart Learning Operation, or SLO-Mode, reduces engine output so newer riders can become familiar with the handling and response of the Jet Ski watercraft at a more relaxed pace. The customer is provided withtwo keys, one for SLO-Mode and the other for full-power operation, to help prevent confusion over which setting is in use.
Furthermore, the electronics package includes a smart Economical Riding Indicator on the digital display. This alerts the rider when the engine is operating in the most fuel-efficient manner, such as when planing at speeds where hull resistance is substantially reduced.
Electric Trim Control (ETC) is another example of the advanced technology that Kawasaki engineers have packed into the Ultra 310R. The ETC allows the rider to control the nozzle angle of the 160mm jet pump to adjust the hull attitude to suit both water surface conditions and riding style. The system has a plus-or-minus range of eight degrees, and it allows the Ultra 310R’s hull to take the fullest advantage of its razor-sharp turning characteristics. 
An advanced impeller design is included on the 310R, with blade angles specifically designed for increased acceleration.During acceleration, when cruising or at high speed, horizontal guide “vanes” on the propulsion grate improve hull tracking and reduce cavitation during acceleration for better hook-up. It all adds up to the most advanced production watercraft propulsion system in the industry.

HULL
The Ultra 301R’s race-derived, fiberglass-reinforced hull is meticulously designed to be both incredibly strong and surprisingly light. Special reinforcements inside the hull help it to retain strength so that its overall thickness can be optimized for low weight, which aids in maneuverability. The hull has an ingenious cleaning system with a two-circuit design, with each circuit utilizing a dedicated flushing port for easy maintenance. Radically edged contours and nose trim combine to give the Ultra 310R’s bow a sleek and aggressive look. 

COCKPIT AMENITIES
Of course, it’s equally important that the Ultra 310R’s cockpit and rider accommodations match its high-performance engine and hull features.Front and center is the highly visible instrument panel with an all-LCD info screen design that’s not only futuristic but also allows the rider easy monitoring of all the machine’s vital information. Aided by a visor foreasier viewing in sunny conditions, the highly legible LCD display boasts a fuel consumption function that can display gallons per hour or gallons per minute, a boost meter scale and riding-mode displays along with a range of other functions, including clock; time, trip and hour meter; digital or bar-graph tachometer; water and air temperature gauges; speedometer and max-speed functions. All of these make keeping track of the Ultra 310R’s vital signs a cinch.
The Ultra 301R’s deck design gives all riders plenty of legroom for ideal comfort, and its triangular-pattern deck materialoffers excellent grip for the rider’s feet. A reverse lever on the left side of the craft features an ergonomically ideal design for easy operation, and optimally curved mirrors offer a wide rear view.

LONG-RANGE TOURING
With 20.6-gallons of fuel capacity – the most in its class – the Ultra 310R allows plenty of range for long-distance rides. Up front, a handy storage bin with a generous 
54-gallons of capacity hides under the front cowl, and dual drink holders keep refreshments within easy reach. Total combined storage capacity for the Ultra 310R is an industry-leading 56 gallons. So you really can take it all with you!
Supreme power, superb handling and comfort, sophisticated, intelligent user-friendly features. These are the attributes that make Kawasaki Jet Ski watercraft legendary in the personal watercraft world, and the Jet Ski Ultra 310R standshead and shoulders above the competition at the pinnacle of the PWC performance genre.
