2017 JET SKI SX-R

Unprecedented Riding Experience

As the pioneer of personal watercraft and the creator of the original mass-produced stand-up model, Kawasaki is pleased to present the JET SKI SX-R, a long-awaited model sure to redefine the standard for stand-up power and handling. Powered by a 1,498 cm³ 4-stroke In-Line Four, the SX-R has twice as much power as its 2-stroke predecessor, the JET SKI 800 SX-R, and a broad spread of power that delivers strong acceleration from any rpm. This massive power is harnessed in a newly designed hull that allows riders to use their whole body as they skilfully control this exciting new model. The 4-stroke JET SKI SX-R breathes new life into the standup category. Its combination of big, yet manageable power and agile, rider-active handling offers a wide range of riders an unprecedented riding experience.

 


 

 

Key Features

  • The marine 1,498 cm³ DOHC inline four-cylinder engine produces 160 horsepower. It’s the most powerful production Stand-Up PWC in history.
  • Superb cornering performance. Development of the new hull incorporated racing feedback.
  • Agile handling complemented by great stability and increased power, allows higher cornering speed.
  • Exceptional stability from a longer and wider hull contibutes to excellent stability in both straight line and in turns.  
  • Wide deck with a larger, wider floor provides more room to move around. 
  • Sleek and sharp styling, reflecting its high race potential. 
  • Injection mould sponsons contribute to overall stability as well as sharp, clean turning performance and a very solid feel when banking.
  • Kawasaki Splash Deflector (KSD): a lateral strip on the forward section of the hull reduces water splash, especially at speed and in rough water.
  • MX-style handlebar features a sporty pad that contributes to the racy looks.

Rider Active Hull

Designed to house the larger engine, the longer, wider stand-up hull offers the best of both worlds: agile handling and superb stability. This combination ensures the high performance required for racing while offering recreational riders a package they can handle with confidence. Development of the new hull incorporated racing feedback. Its agile handling, complemented by great stability and increased power, allows higher cornering speed. Corner grip of the well balanced machine exceeds that of the 800 SX-R. Being 355 mm longer and 35 mm wider, the hull’s larger size contributes to excellent stability in both straight lines and in turns. Sitting high in the water when stopped, the hull’s stability facilitates boarding.

Marine 1,498 cm³ 4-Stroke In-Line Four Engine

DOHC, 16-valve, fuelinjected, 4-stroke In-Line Four engine displaces 1,498 cm³ and has a bore/stroke ratio of 83.0 x 69.2 mm. Compression is 10.6:1. Electronic fuel injection system delivers hard-hitting throttle response. Fuel injection also ensures easy, hassle-free starting with the push of a button. Throttle body diameter of ø60 mm ensures quick response and high power output at all rpm. Valve sizes measure ø33.4 mm (IN) and ø28.3 mm (EX). Narrow valve angles (IN=12°, EX=13°) ensure a highly efficient combustion chamber shape. All-aluminium cylinder with electroplated bores is light, long wearing and offers superior heat dispersion. Coolant water is force-fed from the jet pump. Filter at the inlet prevents debris from entering the system. Redesigned to fit in a stand-up hull, the slim, compact water muffler takes up about 20% less space than that of the STX-15F. It also contributes to low weight. Double-walled water-cooled exhaust manifold provides efficient cooling. Sound absorbing box inside the water muffler contributes to low exhaust noise. Plastic intake manifold designed with feedback from ULTRA 310 Series models contributes to low-rpm acceleration and response. Large-capacity airbox reduces intake noise for quiet operation.

Stainless Steel Grate

Water intake is via a special low-resistance stainless steel intake grate. Its design, although slightly longer, was based on the highly efficient grate of the 800 SX-R.

Stainless Steel Impeller

The 148 mm diameter oval-edged, 3-blade, cast stainless-steel impeller delivers strong acceleration, high efficiency and low cavitation. Tough cast stainless-steel aerofoil is less likely to suffer damage, helping to prevent cavitation erosion. The jet pump drive-line features a large rubber damper to absorb shock loads from the powerful engine, and to reduce drive-line noise. Strong drive shaft complements the engine power; the drive shaft is supported by a sealed bearing.

KSD

The Ultra 310R's Kawasaki Splash Deflector (KSD): The ridges across the bottom of the bow deflect water splashing foward from under the hull. A fourth splash deflector mounted at the top reduces spray duirng high speed turns.

Massive Power

The JET SKI SX-R offers double the power of Kawasaki’s last stand-up model. Its 4-stroke In-Line Four engine – based on that of Kawasaki’s highly successful runabout race platform, the JET SKI STX-15F – also enables a top speed more than 25% quicker than the JET SKI 800 SX-R. Its flat torque curve ensures that the big power is available from very low rpm. The SX-R delivers the impressive performance that racers crave: acceleration is overwhelmingly stronger, and slalom course times are markedly quicker. Compared to the narrow power band of the 2-stroke
800 SX-R, the broad range of 4-stroke power offered by the SX-R is very manageable, facilitating control.

Sponsons

Injection-moulded sponsons contribute to overall stability as well as sharp, clean turning performance and a very solid feel when banking.

Large Deck

Commensurate with its larger hull, the deck features a larger, wider floor area (especially at the front), offering greater freedom of movement. Deck has a forward slant, making it easier for riders to brace against the SX-R’s strong acceleration. The high side deck
fins are easy to use as a point of leverage for the legs. Pads on the inside of the deck fins contribute to grip.

 

 

17JS1500A Handle pole C280x150

Reinforced Handle Pole

The handle pole is a reinforced version of that from the 800 SX-R (to ensure the durability to match the increased power and higher top speed). Its pivot was positioned to reduce the amount of forward/backward movement at the grips, to minimise rider fatigue, particularly during long races.

Convenience & Practical Features

Combined with the efficient 4-stroke engine, the 23 litre fuel tank offers a greater range than the 800 SX-R (which had a 17 litre volume). Indent beneath the handle pole offers convenient storage for small items like rope, flare, etc. Items are secured with a handy rubber net.

17JS1500A Handlebar C280x150

Handlebar and Warning Lights

MX-style handlebar features a sporty pad that contributes to the ski’s racy looks. Handlebar made from stainless steel (aluminium on the 800 SX-R) offers increased corrosion resistance. Engine and fuel warning lamps built into the handle pole pad offer at-a-glance information.

Key Operated

Key-operated magnetic ignition switch discourages theft.  Wrist lanyard connected to the engine stop switch automatically stops the engine should the operator fall overboard.

Sleek Styling

Racy graphics add to the sleek styling while hinting at the SX-R’s high level of performance. The SX-R’s sleek and sharp styling followed the design essence of the 800 SX-R. Its lines were carefully crafted to give the new machine a distinct Kawasaki look (especially from the front) while contributing to a compact-looking package. The reshaped engine hood not only looks great, it gives easy access to the engine compartment, making it easy to install performance parts and to perform maintenance. Hood is made of SMC (Sheet Moulding Compound)

Handy Hull Features

Bilge drain plugs in the hull facilitate after-use draining. Integrated flotation cells make the SX-R virtually impossible to sink.
