About the Kawasaki STX-15F
The Kawasaki ST-15F is the only entry-level jet ski that Kawasaki offers. For years, Kawasaki has been known to produce industry-leading horsepower, and the STX-15F is no exception. It is one of the most responsive models that Kawasaki produces, if not the most responsive of all.
Kawasaki has released several STX-15F models through the years. However, its general layout only has noticeably slight changes. This is because Kawasaki has found an excellent design working well with all the STX-15F models. Kawasaki has decided to keep that design because it is proven to make it a perfect jet ski for beginners.
Next, let’s look at the specs and features of the 2019 Kawasaki STX-15F jet ski:
Kawasaki STX-15F Specs and Features
The capabilities of the 2019 Kawasaki STX-15F are excellent with its 4-stroke, in-line four-cylinder, 1498 cc engine. It can go 0-30 in 2 seconds and performs a top speed of 70 mph.
With its 160 horsepower engine, it provides beginners ample room to grow into their jet skis. Thus, they will not feel any need to upgrade after a few months. Most STX-15F users, if not all, are satisfied with their purchase as they can truly maximize its features.
The 2019 Kawasaki STX-15F jet ski storage has a maximum capacity of 19.5 gallons or 89 liters. This comes standard on this model. It is slightly larger than the storage of its rival entry-level models. With its competitors, owners usually feel the need to upgrade their storage.
This wide storage comes in handy if you use the jet ski for water sports or fishing regularly. Typically, this kind of storage is only found in higher jet ski variants. But Kawasaki has made it available even for their entry-level jet ski model.
Not everyone realizes the importance of spacious jet ski storage. Oftentimes, people realize this too late, when they have already bought one with small storage.
If you think that 89-liter storage is spacious, check out the 2017 Kawasaki STX-15F model. It amazingly has wider storage at 23.5 gallons.
The Kawasaki STX-15F jet ski has a seating capacity for three people. When you say three, there is indeed enough space for each person. Therefore, no one gets cramped.
This model features a low-seat design that makes it more aggressive and responsive. Nonetheless, beginners will feel comfortable riding it.
While it may generally have a seating capacity for three people, exceptionally tall riders might opt not to have passengers with them. That way, they can position themselves farther back on the seat to experience a comfortable ride.
Hull and Deck
This jet ski features a sporty deep-V hull which is an ideal design for stable cornering. While the hull may seem like it is built for racing, it can efficiently handle moderate water conditions. In fact, it is slightly more difficult to ride through choppy water.
When it comes to the deck space, it is noticeably spacious. With the built-in spring-loaded boarding step, it is guaranteed that you can get on and off it conveniently.
Smart Learning Features
For an entry-level jet ski, the Kawasaki STX-15F has impressive safety features that are perfect for beginners. These are the following:
- Smart Learning Operation (SLO)
- Kawasaki Smart Steering (KSS)
Let’s briefly explain the two.
Smart Learning Operation (SLO)
You may limit the top speed of the Kawasaki STX-15F jet ski, depending on your preference. This is to allow you to have a comfortable ride on the watercraft. Once you are familiar with it, you can adjust the SLO mode. A magnetic key activates this mode.
If you notice a separate ignition key that somewhat looks like the SLO mode magnetic key, it is used for theft protection.
Kawasaki Smart Steering (KSS)
The KSS system mainly provides handling assistance when the throttle is released from a high speed. Through this system, the jet ski becomes essentially stable. It minimizes the chances of the rider getting thrown off.
This is such a significant feature for this model since the Kawasaki STX-15F model can perform at high speeds.
