- Eco indicator shows the rider when the speed and throttle opening is in the 310X’s most efficient range
Eaton Twin Vortices Roots-type Supercharger
- 4-lobe, constant-displacement design offers significant performance increase over standard roots-type unit
- System force-feeds the engine 2 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 17 psi of boost pressure.
- 2 different air bypass valves are used to prevent over boosting at low and medium rpm
Electronic Throttle Valve (ETV) with Cruise Control
- Improved Fuel Economy Assistance mode revised for significant fuel savings and increased range
- Convenient electronic cruise control smoothly holds a set speed from 5 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
- 1-touch, push-button 5 mph mode allows hassle-free no-wake zone riding
- Economical Riding Indicator mode can be viewed on a graph on the LCD info screen
- Eco Mode reduces and smoothes engine performance while conserving fuel
Electronic Trim Control System
- Allows the angle of the jet pump nozzle to be controlled to adjust the attitude of the hull to suit water surface conditions and riding styles
- Adjustment range is plus or minus 8 degrees from standard
Exhaust
- 4-into-2-into-1 exhaust system routes the exhaust pipe upward and allows the smoothest path for exhaust gases, maximizing exhaust efficiency
Extra-large Fuel Capacity
- 20.6 gal. fuel tank boasts more capacity than any machine in its class, extending range
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
- 2 separate keys, 1 for SLO mode and 1 for full-power operation, help prevent confusion over which setting is in use
Key Features
- Upgraded supercharged DOHC inline 4-cylinder engine produces a staggering 310 hp, it’s the most powerful production PWC in history
- Upgraded impeller features a revised 3-blade design that gives the 310X greater initial acceleration
- Strong and light, the 310X’s deep-V hull offers superb straight-line tracking and precise cornering performance
- New instrumentation includes a new fuel consumption function, revised boost meter scale, riding modes, external water and air temperature, clock, time, trip and hour meters, tachometer (in digital or graph displays), speedometer and max speed functions
- Eaton TVS constant-displacement supercharger and liquid-cooled intercooler provide instant and consistent boost for outstanding performance throughout the rev range
- Industry-leading, 56 gal. storage capacity lets you bring your gear with you
- 20.6 gal. fuel tank is the largest in its class, providing tremendous range for long rides
- Separate keys for full power operation and Smart Learning Operation
Quattro KSD
- The 310X’s Kawasaki Splash Deflector uses 3 bottom-mounted ridges and an additional deflector mounted at the top to deflect water splashing forward from under the hull
- Whether turning or strait-line riding at any speed, the Quattro KSD minimizes spray, allowing greater rider concentration
Ride Plate
- Features a groove from the center to the rear of the plate to enhance straight-line tracking
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
- Deep-V hull design 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 310X 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 310X’s excellent maneuverability while helping to retain the narrow hull design
