• Two-layer oil cooler offers efficient cooling
• Large cam chain increases reliability in a supercharged engine application
• Reinforced crankcase adds to engine’s durability and reliability
• Fuel pump provides superior fuel flow volume
• Thick water jackets provide significant cooling performance
• Check valve system between the cylinder jacket and water muffler that shuts water flow off above 2,000 rpm, to keep the cooling water inside the cylinder jacket for optimum cooling performance
• Two cooling oil jets per piston for increased piston cooling
• Oil pan features baffle plates to prevent oil slosh during tight turns or extreme acceleration/deceleration
• Crankcase oil return holes offer quick oil return to the oil pan

Eaton Twin Vortices Roots-type Supercharger:

• Four-lobe, constant-displacement design offers significant performance increase over standard roots-type unit
• System force-feeds the engine two liters of air with every revolution, providing a constant supply of high-pressure intake air at all rpm
• Delivers compressed air continuously, not in waves, for smoother power delivery
• Produces large amounts of boost even at low rpm for instant and powerful acceleration right off of idle
• Provides a flat and linear torque curve with mellifluous, lag-free power across the entire rev range
• Produces more low-rpm boost than competitive or aftermarket systems, with a maximum of 17psi of boost pressure
• Two different air bypass valves are used to prevent over boosting at low and medium rpm

Air-to-Water Intercooler:

• Efficiently cools high-pressure intake air – cooler air is denser and makes more power
• Liquid-cooled intercooler design maintains consistent thermal performance

Digital Fuel Injection System:

• High-flow fuel injectors with four orifices are fitted for combustion efficiency
• Single throttle body features a large, 60mm bore diameter Exhaust
• 4-into-2-into-1 exhaust system routes the exhaust pipe upward and allows the smoothest path for exhaust gases, maximizing exhaust efficiency 160mm Jet Pump
• Large-diameter, race-developed 160mm jet pump efficiently converts the Ultra 310R’s massive horsepower output into instantaneous thrust
• Pump is designed to deliver consistent output and good “bite” even in rough water conditions
• Impeller features a 3-blade design that gives the 310R significant acceleration performance at the hit of the throttle
• Eight-vane intake guides and regulates the flow of water to the impeller for consistent, efficient and powerful propulsion

• Features a groove from the center to the rear of the plate to enhance straight-line tracking Electric Trim Control System
• Allows the angle of the jet pump nozzle to be controlled by the rider to adjust the attitude of the hull to suit water surface conditions and riding styles
• Adjustment range is plus or minus eight degrees from standard Electronic Throttle Valve (ETV) with Cruise Control
• Convenient electronic cruise control smoothly holds a set speed from five mph up to top speed
• Accelerator Position Sensor (APS) converts throttle lever input to an electronic signal that’s used to control the throttle valve via an electric motor for crisp and smooth throttle response
• Redundancy in the system helps ensure control is maintained in case of failure
• One-touch, push-button five mph mode allows hassle-free no-wake zone riding
• Fuel Economy Assistance mode provides significant fuel savings and increased range
• Economical Riding Indicator mode can be viewed on a graph on the LCD info screen
• Eco Mode softens engine performance while conserving fuel

Strong, Light Hull Design:

• Designed to emulate the performance of Kawasaki’s IJSBA championship-winning race machines
• Reinforced inner bow is extremely light with ample strength to handle the engine’s power output
• Exemplary straight-line tracking and responsive handling in both calm and rough-water conditions set performance benchmarks for the class
• The lower hull is specially designed to distribute the engine and power delivery loads over a wide area
• The 310R’s deep-V hull enables a steep bank angle for motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding
• The 22.5-degree V-angle at the bottom of the hull helps reduce unwanted spinouts during sharp turns
• Delivers the neutral handling and turning characteristics for which Kawasaki Jet Ski watercraft are famous
• Bottom of the hull slants upward steeply from the center section to the bow, so the Ultra 310R can penetrate swells and waves with less shock, pushing through waves rather than bouncing over them at high speeds
• Integrated sponsons extend from the hull, providing wallow-free straight-line performance and contributing significantly to the 310R’s excellent maneuverability while helping to retain the narrow hull design

Quattro KSD:

• The Ultra 310R’s Kawasaki Splash Deflector uses three bottom-mounted ridges and an additional deflector mounted at the top to deflect water splashing forward from under the hull
• Whether turning or straight-line riding at any speed. The Quattro KSD minimizes spray, allowing greater rider concentration Kawasaki Smart Steering®/ SLO Mode
• Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, intelligently raises rpm to help initiate a turn
• Smart Learning Operation (SLO) allows newer riders to become familiar with the handling and response of this Jet Ski watercraft at a more relaxed pace
• Two separate keys, one for SLO mode and one for full-power operation, help prevent confusion over which setting is in use Comfort and Convenience
• KX motocross-style electro-polished stainless steel handlebar enhances the 310R’s sport riding capabilities while also providing excellent all-day comfort
• 12-position handlebar mount can be adjusted for reach and height to allow operation while standing or sitting and to suit a wide range of riders and conditions
• Sport seat includes a special support bolster and a grippy KX-motocross-like seat cover for hard sport riding
• Passenger handrail is located in an ergo-friendly location to reduce passenger fatigue and features a handle for better grip
