Kawasaki Jet Ski Model Reference [1973-2024]

1973-1975 Kawasaki Jet Ski Lineup

The very first Kawasaki Jet Ski was introduced in late 1972, but mass production of these machines only started in 1975.

After several prototypes, Kawasaki revealed the 1973 Kawasaki WSAA and WSAB stand-up Jet Skis.

The latter featured a V-shaped hull design while the WSAA was built on a flat hull, each of which was made of hand-laid fiberglass.

Although the development of Kawasaki Jet Skis was moved to Santa Ana, California, production of the first machines started in Akashi, Japan.

The limited production of WSAA and WSAB models shared the same 2-stroke, 400cc, vertical-twin Kawasaki engine. This was paired with a high-performance jet pump nestled in a covered nook at the bottom of the hull.

This design ensured great performance as well as high safety since the impeller spun in an enclosed space.

These machines were primarily used for racing and marketing purposes, which the manufacturer used to promote this entirely new sport.

Thanks to hard work and brilliant marketing, Kawasaki Jet Skis instantly became popular with the first model going into mass production in 1975.

1973-1975 WSAA (flat hull)

1973-1975 WSAB (V-hull)

1976 Kawasaki Jet Ski Lineup

The Kawasaki JS400 (JS400-A) was the first mass-produced Kawasaki Jet Ski, which also became the first commercially-successful PWC in history. (The very first Bombardier Sea-Doo failed in the ‘60s.)

Unlike the fiberglass WSAA/WASB, the hull of the JS400 was made of fiberglass-reinforced SMC.

The 400cc twin engine and most features had been carried over from predecessors without any significant changes.

Producing 24.5 HP and 220 pounds of thrust, the JS400 instantly become popular among racers and recreational riders. This proven machine remained in production until 1981.

1976-1981 Kawasaki JS400 (JS400-A)

1977-1981 Kawasaki Jet Ski Lineup

To respond to market demands for more engine power, Kawasaki released the JS440 (JS440-A) for the 1977 season.

This machine inherited its hull and features from the JS400 but had a more powerful, big-bore engine option.

As the name suggests, the power source of the JS440 was a 436cc twin engine rated at 27 HP.

This machine is known as one of the longest-selling Kawasaki Jet Ski since it was produced from 1977 through 1992.

The Kawasaki Jet Ski lineup remained unchanged from 1977 until 1982.

Discover the 1977-1981 Kawasaki Jet Ski models:

1977-1992 JS440 (JS440-A) – NEW1976-1981 JS400 (JS400-A)

1982-1985 Kawasaki Jet Ski Lineup

In 1982 the base JS400 was discontinued to make room for the more innovative Kawasaki JS550 (JS550-A).

This high-performance ski shared its hull and features with the JS440 but enjoyed a larger 530cc, 41 HP twin engine, larger exhaust, a mixed-flow jet pump, and performance sponsons.

This model was manufactured from ’82 through ’85 without any significant changes.

Besides the regular color changes, the only upgrade on the ’84 JS440 and JS550 was a handle pole chin pad.

1982-1989 JS550 (JS550-A) – NEW1977-1992 JS440 (JS440-A)

1986 Kawasaki Jet Ski Lineup

In 1986, Kawasaki heavily redesigned the JS550, allowing it to return with a more innovative engine, exhaust, and pump.

Thanks to these performance upgrades the power of the ski increased from 41 to 47 mph while its top speed jumped from 37 to 39 mph.

The ‘86 JS550 was the first Kawasaki Jet Ski with an innovative automatic RPM control. This feature was intended to prevent the engine from over-revving when the pump was out of the water.

The revamped JS550 was manufactured unchanged from ’86 through ’89 except for some cosmetic changes.

A new model in the 1986 Kawasaki Jet Ski lineup was the lightweight JS300 (JS300-B). This ski was built on the standard JS platform but housed a 294cc, single-cylinder engine rated at 30 HP.

This power mill enjoyed an automatic fuel and oil mixing system, while its larger brothers still ran on premix. Thanks to this oil system and a simple engine, the JS300 was easy to maintain and operate.

But the JS300 wasn’t the only Kawasaki newcomer that year, as the manufacturer released the X-2 (JF650-A) as the first sit-down Kawasaki Jet Ski.

Although this machine was marketed as a sit-down ski rated for two riders, it was primarily ridden in a standing position.

It was built on an extremely small agile hull, housing a 2-stroke, 635cc, twin-cylinder Kawasaki engine rated at 52 HP. This unit enjoyed a water-jacketed exhaust system, 28mm Keihin carburetors, and was paired with an axial-flow, single-stage jet pump.

It was also the first Kawasaki Jet Ski to feature an adjustable trim system and adjustable handlebars.

Thanks to its amazing capabilities and motocross-like handling, the X-2 become widely popular among riders and created a new PWC race category, known as the Sport Class.

This year is also remembered for Yamaha’s entry into the PWC market.

1987-1988 Kawasaki Jet Ski Lineup

In 1987 Kawasaki introduced the sporty 300SX (JS300-A) stand-up, powered by a high-revving, crankcase reed valve, 294cc, single engine. It featured a water-jacketed exhaust, a magneto CDI ignition, and a Mikuni BN38 carburetor.

Unlike the outdated JS300, the 300SX featured an all-new hull and a modern, rounded top deck.

The 650SX (JS650-A) also debuted in this model year, as a high-performance stand-up Kawasaki Jet Ski.

Just like its smaller brother, the 650SX had an all-new V-shaped hull and top deck that offered outstanding stability and maneuverability.

Although these skis were very similar at first glance, the 650SX was larger and heavier than the 300SX.

It also housed a much more powerful, 636cc, 52 HP twin engine matched with a high-performance jet pump.

The X-2 also had some minor updates for this season. Its air intake was relocated while the gas tank vent got a water tap. Its trim system and propulsion system also got some smaller changes.

The 1987 lineup was carried over to the 1988 model year without any significant upgrades.

1989 Kawasaki Jet Ski Lineup

Kawasaki revealed the exciting Jet Mate (JB650-A) for the 1989 model year. This machine was a unique blend of a boat-like hull with a 650cc Jet Ski engine.

Unfortunately, this model was discontinued after only four short years of production.

The all-new TS (JF650-B) a.k.a. Tandem Sport or 650TS also debuted as the first sit-down Kawasaki Jet Ski. (Let’s face it, the X-2 wasn’t actually a sit-down ski.)

It enjoyed a lively 2-seater hull and a 635cc, oil-injected, twin engine rated at 52 HP.

The “squirrel cage” steering system of the X-2 was replaced with a direct cable linkage, which proved to be less responsive. Its CDI ignition also got a rev limiter.

In 1989 the manufacturer eliminated the base JS300, and this was also the last year for the JS550.

1990 Kawasaki Jet Ski Lineup

In 1990, the Kawasaki 550SX (JS550-B) debuted as a revamped configuration of the JS550.

It inherited its JS hull and engine from its predecessor but got many performance upgrades including a high-capacity, mixed-flow jet pump.

It was also equipped with a fuel-flow rev limiter, a bilge siphon system, and a self-circling mode.

This was the last year of the original JS hull since the 1991 550SX got an all-new body.

The X-2 got back its squirrel cage steering system but its metal reed petals were replaced with plastic.

1991 Kawasaki Jet Ski Lineup

The 1991 550SX (JS550-C) was completely redesigned for this season. Unlike its JS-based predecessor, this ski was built on an entirely new platform designed from scratch.

The engine was also upgraded with many performance-enhancing features including piston reed valves, dual piston rings, aluminum cylinders, an electronic rev limiter, and a single Keihin CDK 38-32 carburetor.

It also got an advanced underwater exhaust outlet, which ensured a sleeker design and a quieter operation.

The 1991 650SX (JS650-B) was also upgraded with some more advanced features including a more advanced carburetor, and an underwater exhaust outlet.

The sit-down Kawasaki Jet Ski family was also expended with the SC (JL650-A), which was often referred to as the 650SC. This weird ski featured a side-by-side seat and a car-like steering wheel.

The 650SC was the first Kawasaki Jet Ski that featured a mechanical reverse system.The X-2 also got some important upgrades including a 38mm Keihin carburetor, a strengthened crankshaft, and a revamped waterbox.

This was the last year of the lightweight, single-cylinder 300SX.

1992 Kawasaki Jet Ski Lineup

The all-new, high-performance 750SS (JH750-A) was released as a sporty 2-seater runabout Jet Ski.

It was built on a fiberglass-reinforced SMC hull and enjoyed a 743cc, oil-injected, single-carb engine configuration. This ski became the predecessor of many popular 2-seater Jet Skis including the dual-carb Super Sport Xi (SS Xi), and the Xi Sport.

It came standard with many innovative features including a display panel, shut-off safety lanyard, storage compartments, and a finger throttle lever.

The 750SS shared its 743cc, 63 HP engine with the new 750SX (JS750-A). This high-performance stand-up was bigger and much more powerful than its smaller-displacement brothers.

The X-2 only got some minor upgrades for this season, including the flush fitting and wire harnesses.

This was also the last year for the unique Jet Mate and the outdated JS440.

1993 Kawasaki Jet Ski Lineup

Kawasaki introduced its first twin-carb engine in the Super Sport Xi (JH750-B), the successor of the 2-seater 750SS.

This power mill was based on the proven single-carb 750 engine, but it featured twin Keihin CDK 40-34 carburetors. Thanks to this upgrade, the engine delivered 75 HP while its single-carb counterpart was only rated at 63 HP.

For optimal performance, this engine was paired with a high-performance jet pump housing a five-blade, stainless-steel impeller.

In 1993, Kawasaki dropped the exciting Jet Mate and it was also the last year of the 650SX.

1994 Kawasaki Jet Ski Lineup

In 1999, the first 3-seater Kawasaki Jet Ski hit the water. The ST (JT750-A) was designed with the single-carb (63 HP) engine option, which didn’t prove to be enough for its heavy platform.

Although it was advertised as a 3-seater model, riding it with two adult passengers was virtually impossible and its top speed was only 40-42 mph.

Due to its underpowered engine, the ST never become popular and was phased out by the much more powerful STS in 1995.

Another lesser-known Jet Ski, the Super Sport XiR (JH750-D) was also revealed this year. This ski was a limited edition racing model of which only 500 units were released.

Its special hull featured carbon fiber reinforcement and housed a factory-installed aftermarket exhaust system. It wasn’t an extremely fast ski but it did have outstanding cornering abilities

The X-2 got some upgrades for this year including new, 40mm Keihin carburetors, extra foam for better floatation, and a new color scheme. Its engine power jumped from 52 to 57 mph.

1995 Kawasaki Jet Ski Lineup

Kawasaki Jet Ski enthusiasts were spoiled with a lot of changes in 1995.

The biggest news was arguably the introduction of the first triple-cylinder Kawasaki Jet Ski, the 2-seater 900 ZXi (JH900-A). The power source of this ski was an all-new 2-stroke, 891cc, crankcase reed-valve, triple Kawasaki marine engine.

Thanks to its advanced features and triple-carb configuration, this responsive power mill produced a whopping 100 HP.

The 900 ZXi was also the first Jet Ski designed with an electronically operated trim control. This system allowed you to adjust the vertical angle of the jet nozzle based on riding conditions.

Other innovative features of the ZXi included rich instrumentation, digital CDI ignition, dual mirrors, magnetic ignition key, a shut-off valve with safety lanyard, and a stainless-steel impeller.

Thanks to its advanced design and features the 900 ZXi was crowned “Watercraft of the Year” in 1995.

The 750 ZXi (JH750-C) also debuted this year as the smaller brother of the 900 ZXi. These skis shared their platform and most features, but the 750 ZXi had an 83 HP twin engine option.

Another new model was in the fleet, the high-performance 750 SXi (JS750-B), which was the first twin-carb stand-up Kawasaki Jet Ski in history.

It was the successor of the single-carb 750SX and housed many advanced features, like a stainless-steel, 3-blade impeller, automatic bilge pump, engine shut-off valve, and a durable aluminum waterbox.The 3-seater, twin-carb STS (JT750-B) or 750 STS also reached showrooms in 1995. This ski was an upgraded version of the underpowered 750ST.

Kawasaki also upgraded its 750 engine this year. Due to changes in its design, the original engine was often referred to as the “Small Pin” while the new configuration was known as the “Big Pin.”Although this revised power source went into production in 1995, the manufacturer used both Small Pin and Big Pin 750 engines in that year.

Regarding differences, the Small Pin 750 Kawasaki engine was rated at 63 HP and was ported for bottom-end power. It was also ensured less durable due to weaker internals.

In contrast, the Big Pin 750 was tuned for speed and delivered 70-83 HP depending on the model and the number of carburetors. It featured some more durable internals like a revamped crankshaft, and larger connecting rod ends and wrist pins (hence the name “Big Pin”).

The Small Pin engine was used primarily in the early 750SX models and the 750 ST, while the Big Pin founds its way to the later 750 Jet Skis including the Super Sport Xi, 750 ZXi, (1996-) SS, STS, 750 STX, and the SXi Pro.

Many great Jet Skis were retired after the 1995 season like the ST, Super Sport Xi, 750SX, 650SC, 550SX, and the X-2.

1996 Kawasaki Jet Ski Lineup

The high-performance 1100 ZXi (JH1100-A) debuted as the high-end, 2-seater Kawasaki Jet Ski.

It was powered by the 2-stroke, 1071cc, triple-carb, 3-cylinder engine rated at 120 HP. This unit was actually a big-bore configuration of the proven 891cc Kawasaki marine engine.

The new 1100 ZXi packed many advanced features including a large dashboard with a lot of analog instruments, two Kawasaki Splash Deflectors, and the Kawasaki Automatic Trim System (KATS).

The Super Sport Xi (JH750-F) was also heavily redesigned for this season. The revamped model featured an upgraded hull design with splash deflectors, completed with a new saddle and a pair of high-performance sponsons.

Its twin-carb engine was also upgraded to a Big Pin configuration, translating to more engine power (75 HP) and more durability.

The SS or more commonly known as the 750SS (JH750-E) also got a more powerful Big Pin, single-carb engine rated at 70 HP. This increased engine power was paired with a new impeller and an upgraded electric trim system.

Engine power of the 3-seater STS (750 STS) was also increased from 80 to 83 HP.

The outdated 650TS reached dealerships for the last time this year.

1997 Kawasaki Jet Ski Lineup

By 1997, Kawasaki had discontinued the 650TS but released the all-new STX family, as a 3-seater runabout line.

This series included the flagship 1100 STX (JT1100-A) and the base 900 STX (JT900-A), which became the mid-range model after the introduction of the 750 STX in 1998.

As the names suggest, the 900 STX shared its 891cc, 100 HP engine with the 900 ZXi, while the 1100 STS and 1100 ZXi enjoyed the same 1071cc triple rated at 120 HP.

These models shared the same all-new 3-seater STX platform, which had built a reputation for great handling and stability.

The perfect blend of this hand-laid fiberglass hull with powerful engines made the STX line an ideal family Jet Ski. Therefore, they were commonly used for touring and even tow sports.The 1100 STX was also the first Jet Ski manufactured with Keihin CDCV carburetors. Compared to the regular CDK carbs, the CDCV was more durable and ensured better fuel economy. On the other hand, it was much harder to tune and work on.

In the following years, the CDCV carburetors found their way into many other Kawasaki Jet Ski engines.

After the 1997 model year, Kawasaki discontinued several models including the 750/900 ZXi, 750SS, 750 SXi, and the 750SS.

1998 Kawasaki Jet Ski Lineup

In 1998 the Kawasaki Jet Ski lineup had been heavily revamped.

The Xi Sport (JH750-G) was released as the more powerful configuration of the proven Super Sport Xi.

It returned with a more powerful 80 HP engine, a slightly redesigned top deck, and a fiberglass-reinforced SMC hull.

Another exciting new model in the lineup was the stand-up SXi Pro (JS750-C), marketed as the successor of the high-performance 750SXi.

These skis shared the same 2-stroke, 743cc, dual-carb, 75 HP, vertical twin engine, but the SXi Pro came without an oil injection system. It was also built on a revamped hand-laid fiberglass hull that ensured faster speeds and better handling.

Its advanced hull design and powerful engine made the SXi Pro one of the most successful racing Jet Skis of its time.

Kawasaki also re-introduced the 550SX (JS500-C) in Japan dressed in a unique white and black design. Only 300 of this “Commemorative Edition” 550SX were manufactured, and many of them landed with private collectors.

The 750 STX (JT750-C) also debuted in 1998 as the smallest member of the popular 3-seater SXT family. It inherited its hull and top deck from its bigger brothers, but it got the 743cc, twin engine option rated at 73 HP.

The Keihin CDK-38-29 carburetors of the 1100 ZXi were replaced by Keihin CDCV 38 carbs for this year.

1999 Kawasaki Jet Ski Lineup

For the 1999 model year, Kawasaki released the amazing Ultra 150 (JH1200-A).

As the model name suggested, this ski was powered by a 2-stroke, triple-carb, 1176cc, 3-cylinder engine rated at 150 HP.

The Ultra 150 was built on a modified ZXi platform and packed many advanced features including DC-CDI ignition, Kawasaki Throttle Responsive Ignition Control (K-TRIC), variable-rate Superlube oil injection system, and three Keihin CDCV40-35 carburetors.

Its advanced features and innovative hand-laid fiberglass hull made the Ultra 150 an instant winner on racecourses.

The popular STX 900 (JT900-B) got some upgrades including a revamped top deck design, housing a larger fuel tank and oil reservoir.

A limited-edition racing replica of the 1100 STX was released under the name 1100 STX-Limited (JT1100-D). It featured special 2-piece sponsons and a unique color scheme.

Kawasaki only marketed 300 of these skis exclusively in Japan.

To the regret of many Kawasaki enthusiasts, the 1100 STX and its commemorative replica, as well as the Xi Sport were eliminated after the 1999 season.

2000 Kawasaki Jet Ski Lineup

For the Millennium, Kawasaki introduced its first fuel-injected Jet Ski, the 1100 STX D.I. (JT1100-C).

It was built on an upgraded configuration of the proven STX platform, but its 2-stroke, 1071cc, triple engine featured an advanced Ficht fuel injection system.

Compared to its fuel-injected siblings, the 1100 STX D.I. delivered more power (130 HP) plus it had better fuel economy.

2001 Kawasaki Jet Ski Lineup

In 2001 the all-new Kawasaki Ultra 130 D.I. (JH1100-B) reached dealerships.

This ski was a combination of the advanced Ultra platform with the fuel-injected, 130 HP engine of the 1100 STX D.I.

The 1100 STX D.I. (JT1100-F) also got some upgrades for this year including a Kawasaki Smart Steering™ system (KSSTM), which was virtually an off-throttle steering assist system.

The 900 STX (JT900-C) was also revamped and got the more advanced hull of the 1100 STX D.I. It also returned with a more comfortable saddle and an enlarged front storage.

Since the 750 SXi Pro was discontinued for this season, the 2001 Kawasaki lineup surprisingly didn’t include a single stand-up Jet Ski!

2002 Kawasaki Jet Ski Lineup

In 2002 Kawasaki introduced the amazing 1200 STX-R (JT1200-A), which won the Pro Runabout 1200 Superstock championship of IJSBA in the 2003 season.

This purpose-built racing Jet Ski was built on the 1100 STX D.I. platform but borrowed its engine from the Ultra 150.

Special features included race-intended sponsons and ride plate, digital DC-CDI ignition with K-TRIC, and triple Keihin CDCV 38 carbs.

2003 Kawasaki Jet Ski Lineup

The innovative 2003 STX-12F (JT1200-B) was released as the first 4-stroke Kawasaki Jet Ski.

Its platform was based on the STX family but it was powered by a 4-stroke engine derived from the Ninja ZX-12R motorcycle.

This power mill was a 4-stroke, 1199cc, fuel-injected, DOHC, 4-cylinder engine rated at 125 HP. It ensured outstanding fuel economy and a smooth operation.

Another big bang in the 2003 Kawasaki Jet Ski lineup was the all-new 800 SX-R (JS800-A), which reshaped the entire stand-up PWC market.

The platform of this ski was designed from scratch and housed a 2-stroke, 781cc, twin engine rated at 80 HP.

It was also the last year of the long-lived 1100 ZXi.

2004 Kawasaki Jet Ski Lineup

The high-performance Kawasaki STX-15F (JT1500A) was revealed as a more advanced configuration of the STX-12F.

These skis shared the same platform but the STX-15F enjoyed an all-new 4-stroke, 1498cc, DOHC, fuel-injected, 4-cylinder engine rated at 160 HP. Like its smaller brother, this power mill was also derived from the Ninja ZX-R motorcycle series.

The popular SXT-15F remained part of the lineup until 2020 when it was phased out by the STX 160 series.2004 was also the last production year of fuel-injected Kawasaki Jet Skis including the 1100 STX D.I. and the Ultra 130 D.I.

2005 Kawasaki Jet Ski Lineup

Surprisingly, 2005 was the first year that Kawasaki didn’t introduce any new Jet Ski models.

Plus, the two race-intended models, the 1200 STX-R and the Ultra 150 were discontinued after this season.

2006 Kawasaki Jet Ski Lineup

In 2006 Kawasaki re-introduced the legendary X-2 (JF800-A1) in Europe.

This limited-edition machine was often referred to as the second-generation Kawasaki X-2, and with good reason.

It was built on a brand new platform and shared its 2-stroke, 781cc, 80 HP with the 800 SX-R.

To the greatest regret of many fans, this model was never officially marketed in the U.S. due to emission restrictions.

Since the X-2 was a lesser-known ski, the Japanese manufacturer wanted to reserve all of its EPA emission credits for the widely popular 800 SX-R.

2006 was also the last year for Kawasaki’s 2-stroke sit-down Jet Skis in the U.S.

2007 Kawasaki Jet Ski Lineup

For 2009 Kawasaki discontinued the 900 STX, the last 2-stroke sit-down Jet Ski.

As compensation, the all-new 4-stroke Ultra family made its debut this year including the naturally-aspirated Ultra LX (JT1500C) and the supercharged Ultra 250X (JT1500B).

These skis were built on the huge heavy Ultra platform, which remained in production until 2022.

In terms of a power source, the Ultra LX shared its 4-stroke, 1498cc, 160 HP engine option with the STX-15F. The Ultra 250X engine was a supercharged configuration of this base engine rated at 250 HP.

This incredible power mill was the first supercharged Kawasaki Jet Ski engine, and made the Ultra 250X the most powerful PWC of its time.

With the introduction of this new series, the popular STX-15F was downgraded to the mid-range model in the fleet.

The smallest 4-stroke Jet Ski, the STX-12F, was marketed for the last time this year.

2008 Kawasaki Jet Ski Lineup

The 2007 Jet Ski lineup (except the STX-12F) was carried over for 2008 without any significant changes.

With the absence of the SXT-12F, the STX-15F became the entry-level runabout Jet Ski in the fleet. Its bigger brothers, the Ultra LX and 250X were still part of the lineup.

Production of the second-generation X-2 was stopped after this season.

2009-2010 Kawasaki Jet Ski Lineup

In 2009 Kawasaki released the Ultra 260X (JT1500E) as a revamped version of the Ultra 250X.

The supercharged engine of this ski got some performance upgrades, which ensured a power increase of 10 HP.

Unlike its power source, the platform and the features of the 260X were carried over from its predecessor without any noticeable changes.

The 2010 Kawasaki lineup was almost identical to the 2009 lineup except for some cosmetic upgrades.

2011 Kawasaki Jet Ski Lineup

For 2011 the supercharged 1498cc engine was redesigned for more power, to keep up with the performance of its competitors. The revamped engine delivered an incredible 300 HP along with plenty of torque.

Reflecting on this change, the Ultra 260X was rebranded to Ultra 300X (JT1500H) and it got a brother, the Ultra 300LX (JT1500J).

The latter was considered the luxury model, featuring a bolstered luxury seat, sound system, and a special metallic paint job with chrome elements. But apart from these differences, these two Jet Skis were identical.

They shared the same platform, the 300 HP supercharged engine, and a revised pump rated at a maximum thrust of 1,769 pounds.

This was the last year of the widely popular 800 SX-R stand-up ski.

2012-2013 Kawasaki Jet Ski Lineup

In 2012 there weren’t many changes in the lineup except for the disappearance of the 800 SX-R.

To the regret of many fans, Kawasaki hadn’t manufactured stand-up Jet Skis from 2012 through 2017, until the introduction of the SX-R 1500.

The 2012 and 2013 Jet Ski lineup was almost identical except for some cosmetic changes.

2014 Kawasaki Jet Ski Lineup

In 2014, the performance of the supercharged, 1498cc engine was boosted from 300 to 310 HP.

Therefore, the 300X and 310LX were rebranded again to 310X (JT1500N) and 310LX (JT1500M).

The Ultra 310 family was completed with the race-intended 310R (JT1500L/P). This model featured non-adjustable race handlebars, a special sport seat, and a unique color scheme.

In contrast, the 300X and the 310LX came standard with adjustable handlebars and different seat designs. The 310LX was also equipped with a JetSound audio system.

2015-2016 Kawasaki Jet Ski Lineup

While competitors came up with more and more developments, there weren’t any significant changes in the Kawasaki Jet Ski lineup from 2014 through 2016.

Although Kawasaki Jet Skis were known for their advanced technology and great reliability, they still lacked an electric brake and reverse system.This was a huge competitive disadvantage since rival manufacturers were already offering their models with advanced brake and reverse systems at that time (Sea-Doo iBR: 2008, Yamaha RiDE: 2015).

2017 Kawasaki Jet Ski Lineup

In 2017 Kawasaki stand-up Jet Skis made a comeback with the introduction of the amazing SX-R 1500 (JS1500A).

This ski was built on an entirely new platform, which was significantly larger and heavier than its 2-stroke predecessors.

The SX-R 1500 borrowed its engine and jet pump from the proven STX-15F. Its claimed performance was 160 HP and it delivered a maximum thrust of 955.6 pounds, which translated to a top speed of 62-63 mph.

Not bad for a stand-up ski!

The rest of the lineup was basically identical to 2016’s except for some minimal design upgrades.

2020-2021 Kawasaki Jet Ski Lineup

In 2020 Kawasaki discontinued the proven STX-15F. This long-lived model had been produced from 2004 through 2019 without any major upgrades.

The successor of the STX-15F was the new STX 160 family, which was made up of the base STX 160 (JT1500RLF), the mid-range STX 160X (JT1500SLF), and the high-end STX 160LX (JT1500TLF).

These skis inherited their hull, engine, and jet pump from their predecessors but they got a refreshed top deck and new bells and whistles. Unfortunately, they only featured a mechanical reverse system, which wasn’t intended to be used for braking.

This lineup was carried over to the following year almost unchanged.

2022 Kawasaki Jet Ski Lineup

In 2022 Kawasaki completely redesigned the entire Ultra 310 series.

The new models were released under the names Ultra 310X (JT1500XNFNN), Ultra 310LX (JT1500KNFNN), and Ultra 310LX-S (JT1500WNFNN).

Each of them shared the same all-new hull and top deck, featuring innovative “gullwing” gloveboxes. They also came standard with many bells and whistles including a large LCD instrument panel and the innovative Kawasaki Smart Reverse with Deceleration (KSRD).

The latter does the same job as the Yamaha RiDE and Sea-Doo iBR electric brake and reverse systems.

One of the main differences between these systems is that the KSDR is controlled by a thumb lever mounted on the right handlebar, while the competitors use a finger brake lever on the left handlebar.

Unlike the platform and the features, the engine and the pump of the Ultra 310 line were lifted over unchanged from predecessors.

The non-supercharged Ultra LX with the “old” Ultra platform was part of the lineup for the last time.

These skis were almost identical to the Ultra 310LX and LX-S, except that they arrived with the non-supercharged, 160hp engine option.

Another noticeable change for this year was a new name for the stand-up ski, which was rebranded to the SX-R 160 (JS1500APFNN) from SX-R 1500. Aside from some new decals, these skis are completely identical.

The rest of the lineup was carried over unchanged from 2022.
