The Kawasaki X2 Jet Ski, first introduced in 1986, has a lean-in “sports” design that can accommodate two people with ease. The X2 is powered by a 650 cc gasoline engine. Later on, Kawasaki introduced other variants of the X2, each with its own distinct name. 

The X2 models have the same motor and pump as three other Kawasaki jet skis, namely the Jetmate, the TS650, and the JS650. Later in 2006, Kawasaki re-launched the X2.

This new iteration has a completely redesigned top deck and hull but uses the same motor and pumps, the most popular standard model.

About the Kawasaki X2 Jet Ski

Kawasaki X2

Kawasaki X2, a Jetski model with a 650 cc gasoline engine, was introduced by Kawasaki in 1986. At first, this X2 was designed to accommodate two-person.

Later on, Kawasaki introduced other variants of the X2, each with its own distinct name. 

Almost everyone knows what a jet ski is. However, they assume that it is a generic name for personal watercraft. That is a wrong assumption since it is a name coined by the Kawasaki Heavy Industries to brand their own PWCs.

In other words, when you speak about jet skis, you are technically referring to Kawasaki PWCs.

But just like what happened to Colgate for toothpaste and Kodak for cameras, jet skis became the ‘generic’ name of PWCs. Therefore, it is correct to state that Kawasaki started the craze for speed machines on the water.

In 1986, Kawasaki introduced a two-person Jet Ski model and named it Kawasaki X2. It has a 650 cc engine and designed with a lean-in “sport” style handling.

Over the succeeding years, Kawasaki would come out with other models of the Kawasaki X2:

  1. 800SXR
  2. Ultra 250/260
  3. SXR 1500

In celebration of the 30th anniversary of its Jet Ski brand, Kawasaki released a special edition of the SXR in 2003. The company also updated the X2, based it on the SX-R platform, and re-launched it in Japan.

According to Kawasaki X2 review, Kawasaki’s jet skis are some of the fastest in the world. They are also reliable and can be modified according to the whims and wishes of their owners.

The 2007 Honda Aqua-Trax R-12 X has additional features that both the Kawasaki 800 SXR and the 2021 Yamaha Wave Runner Superjet don’t have.

These additional features are:

  • Digital instrumentation is standard in this model.
  • Storage – this Honda Jet Ski has two storage sections. One is at the front storage well, and the other is at the glove box/dash storage.
  • Rearview mirrors – this model also has two rearview mirrors.


From the comparison table above, the Kawasaki 800 SXR is the most affordable of the three brands of PWCs. Moreover, the Kawasaki Jet Ski’s lesser price is due to its engine type and size.


The Kawasaki 800 SXR has a two-stroke engine, while the Yamaha Waverunner has a three-stroke engine and the Honda Aqua-Trax has a four-stroke engine.

It also has the smallest engine displacement among the three, with only 781 ccs against Yamaha’s 1,049 ccs and Honda’s 1,235 ccs.

Thus, having the smallest engine of the three, the Kawasaki 800 SXR can only produce a total horsepower of 80 hp against Yamaha’s 100 hp and Honda’s 165 HP.

Kawaski X2 review

With the smallest engine, the Kawasaki 800 SXR can only attain a top speed of 48 mph, while Yamaha Waverunner can reach up to 54 mph, and the Honda Aqua-Trax can achieve a maximum of 75 mph.

But what makes the Kawasaki 800 SXR attractive to regular watercraft enthusiasts is its very affordable price. In fact, against Honda’s $ 10,749 and Yamaha’s $9,499 tag prices, you can buy the Kawasaki 800 SXR for only $6,049. That’s quite a difference of about $3,000 to $4,000.

How Kawasaki ‘Invented’ the Jet Ski

The Kawasaki Heavy Industries of Japan first became known around the world as a high-quality motorcycle manufacturer. However, jet skis were not its original products. But they invented the word.

Early History of Personal Watercrafts

The first personal watercraft was invented and developed in Europe and the United Kingdom in the mid-1950s.

During the 1960s, an American, Clayton Jacobson II, designed and developed his own PWC version. Moreover, Bombardier, a Canadian company, came up with their own PWC design based on Jacobson’s work. Bombardier started selling their PWCs right after.

Kawasaki and the Modern Jet Ski

However, all these earlier versions of PWCs gain minimal success. Only a few thousand machines were being ordered from around the world. And then, in 1972, Kawasaki started developing and manufacturing a fresh version of the personal watercraft.

Kawasaki first called its invention the Water Jet. They later changed the name to Power Ski. Later on, they eventually settled for the Jet Ski brand name, which caught the attention of water sports hobbyists, and the rest is history.

Now all personal watercraft of any brand are assumed by many as jet skis. They don’t know that it is the name brand of Kawasaki. This is just like what happened to Colgate for toothpaste and Kodak for cameras – during the early consumerism days.

Kawasaki X2 Models

In 1973, Kawasaki launched a limited jet skis’ stand-up model based on Clayton Jacobson’s design, its original inventor.

Furthermore, it was followed by the mass production of the JS 400-A model, which was powered by a 400 cc two-stroke engine. The market was agog with the new watercraft.

Then in 1986, Kawasaki made more innovations with its jet skis and came with a two-person model. This new machine had a lean-in “sport” styling and was powered by a bigger 650 cc engine. Thus the Kawasaki X2 model line-up was born.

In 2003, in celebration of the 30th anniversary of Jet Ski’s birth, Kawasaki released a special edition of its SX-R model. Kawasaki also updated its X-2 line and based it on the SX-R platform. Then the company re-released it in its home country.

Two Kawasaki X2 Jet Ski models that are the most well-known in the water sports circle are the 800 SXR and the Ultra 250/260. We have discussed in detail the 800 SXR. Also, the Ultra 250/260 is much bigger and more powerful.

It can accommodate from three to four people. In fact, the power of the engine of this PWC is a huge 260 brake horsepower. Besides, it can reach 30 mph in only 1.8 seconds and has a top speed of 65 mph. Some say it can even surpass that speed mark.

This X2 Kawasaki Jet Ski is big as it is 11 feet long and about 4 feet wide. However, it is not a cheap machine. In fact, you have to shell out $11,999 if you want to own and enjoy this big speed beast.

Conclusion: Kawasaki X2 Jet Ski Specs and Review

The Kawasaki X2 is a class of Jet Ski models made by Kawasaki Heavy Industries of Japan. These jet skis are made for more than just one person. It was in 1986 that Kawasaki introduced its X2 class of jet skis. A 650 cc gasoline engine delivers power for this Jet Ski.

Later on, Kawasaki introduced other variants of the X2, each with its own distinct names. These X2 models are fast, reliable, and offer fun and excitement to water sports enthusiasts worldwide. Lastly, the best-known Kawasaki X2 jet skis are 800 SXR and the Ultra 250/260 models.
