Long-Term Test: Kawasaki Z900 RS and Z900 RS SE

The Kawasaki Z900RS has earned a remarkable reputation in the neo-classic motorcycle segment thanks to its blend of retro aesthetics and modern technology. To see if this bike is more than just a pretty facade, I decided to test it on a demanding journey: over 2,500 km from Austria to Montenegro, tackling everything from fast highways to twisty mountain passes and roads in varying conditions.

In this article, I'll honestly share the highs, the lows, and the areas where the Z900RS still has room for improvement.

One of the first things that stands out about the Kawasaki Z900RS is its design. The Japanese brand has expertly captured the essence of the 1970s bikes without compromising on today's standards of quality and finish.

The fuel tank is particularly notable. Kawasaki chose a meticulously crafted and authentic paint job, avoiding cheap solutions like stickers. Additionally, details such as the dual analogue clock instrumentation, complemented by a small digital display in the center, contribute to that retro experience without sacrificing modern practicality.

However, this purity in design also means less electronics and fewer rider aids compared to some current rivals. The absence of systems like a modern TFT display or advanced electronic aids might disappoint some, but for those seeking a pure and straightforward riding experience, this is more of a virtue than a flaw.

Ultimately, in terms of design and construction, the Z900RS scores high marks, displaying a harmonious blend of classic and modern, with materials and finishes worthy of a premium motorcycle.

The heart of the Kawasaki Z900RS is a 948cc in-line four-cylinder engine delivering 111 HP. But beyond the numbers, what really stands out is its character: smooth, powerful, and pleasantly refined.

The power delivery is progressive and predictable, with enough mid-range punch that you don't constantly need to shift gears. At the same time, revving it up to the higher range is an auditory delight, thanks to a well-tuned exhaust that adds character to every acceleration without becoming a nuisance on long rides.

While the six-speed manual gearbox is precise and smooth (not a single hiccup or trouble finding neutral over 2,500 km), an optional quickshifter would have complemented the bike's dynamic nature. However, for purists, this might be irrelevant or even a positive.

One area where the Z900RS could improve is its weight: at 216 kg, it's not particularly light. Though this is hardly noticeable in motion thanks to the excellent balance of the chassis, it can feel a bit heavy during slow maneuvers or in urban traffic.

In summary, the engine is undoubtedly one of the strong points of this bike: refined, with enough power for any situation, and an appealing character that invites you to enjoy the ride without rushing.

The chassis of the Kawasaki Z900RS is a tubular steel Trellis design, effectively blending rigidity and flexibility. This structure directly contributes to the stability and precision the bike offers in fast corners and winding roads.

The standard Kawasaki Z900RS suspension doesn't provide full adjustability and is fairly basic. The inverted front forks (USD) are non-adjustable, and at the rear, the monoshock only offers basic preload adjustment.

On the other hand, the Z900RS SE version features higher quality and adjustable suspension, providing full adjustment for both the front forks and the rear shock, and includes premium components like the Öhlins rear shock.

This difference between versions means that the standard Z900RS is more limited if you're looking to tweak the dynamic behavior to your personal preferences or for more demanding riding. In contrast, the Z900RS SE is a better option if you value the ability to adapt the bike to different riding styles or routes.

On good roads, the Z900RS feels stable, noble, and predictable. It's not an ultra-light or extremely agile bike, but it does inspire great confidence when tackling fast curves or twisty paths securely.

When the tarmac deteriorates, the suspension shows its limitations. It absorbs moderate irregularities without issue, but on particularly broken or bumpy roads, it quickly becomes clear that it is not a trail bike nor does it aim to be. Nevertheless, overall comfort is acceptable even on long rides.

Although it is not an authentic Sport-Tourer, the relaxed ergonomics, along with a plush and comfortable seat, allow for long journeys without too much discomfort.

In the braking department, the Kawasaki Z900RS is equipped with a system that, while effective, could benefit from some tweaks to achieve a more sporty and precise experience.

At the front, it features dual 300 mm discs with radial calipers, while the rear has a single 250 mm disc. This setup provides ample stopping power for safe braking in everyday situations and during relaxed rides. However, if you're aiming for more assertive braking, especially at high speeds or when riding aggressively on mountain roads, you'll notice some weaknesses.

The main critique is the brake lever feel. Although the radial calipers offer good power and progression, the initial bite could be more direct and firm. Additionally, the standard ABS tends to activate a little earlier than desired during hard braking, reducing precision in more demanding situations.

This behavior becomes more apparent due to the bike's weight (216 kg). In strong and late braking into corners, you'll clearly notice the inertia. While it's not severe or dangerous, those accustomed to lighter, more sporty bikes might miss a bit more punch from the brakes.

A simple and effective improvement would be to install steel braided lines and higher-performance brake pads, which would significantly enhance the feel and effectiveness during intense braking. All of this comes standard with the SE version of the Z900 RS.

The Kawasaki Z900RS isn't known for being the fastest, lightest, or most technologically advanced, but it truly shines in an area many modern bikes have forgotten: offering an authentic and sensation-filled experience.

You sit more "on top" of the bike rather than "in it" like the standard Z900. The riding position is excellently designed, with a high and wide handlebar, comfortably positioned footpegs, and a broad, well-cushioned seat. Thanks to this ergonomic setup, you can enjoy long rides without significant discomfort. It's a bike designed to savor every kilometer, not necessarily to devour them in record time.

In the city, its performance is decent although, as mentioned, its weight can be a drawback in heavy traffic. Nonetheless, the smoothness of the engine at low revs and a fairly reasonable turning radius help ensure urban riding isn't overly uncomfortable.

On open roads and fast curves is where the Z900RS truly shows its best side: the stability of the chassis, the motor's progressiveness, and its evocative sound create a unique experience. The bike feels predictable and secure, inviting you to enjoy the ride calmly. This is enhanced by its mechanical throttle, rather than ride-by-wire, providing extraordinary feedback about what's happening with the bike. It's something hard to explain.

On the highway, as is logical and normal, the lack of aerodynamic protection limits comfort at high speeds over extended periods. To address this "issue," you can always fit a small screen to reduce wind pressure on the rider, especially on long routes.

In conclusion, riding the Z900RS is a pleasure, a classic experience framed in modern performance, designed for those who value enjoyment over pure numbers.

After covering over 2,500 kilometers, here are the key takeaways on the Kawasaki Z900RS:

The Good:

• Design and Finish: Excellent quality, attention to detail, and a flawlessly executed retro aesthetic.
• Engine: Smooth, powerful, and with an addictive sound. Provides ample thrust for any situation.
• Comfort: Comfortable and ergonomic riding position for long routes or daily use.
• Chassis: Stable, balanced, and predictable, inspiring confidence on all types of roads.

The Bad:

• Heavy Weight: At 216 kg, it feels heavy during slow maneuvers or in the city.
• Brakes Could Be Better: Good overall performance, but they lack a bit more bite and firmer feel for sportier riding.
• Limited Technology: While simplicity is part of its charm, some riders might miss more advanced electronic aids.

Is it worth it? Definitely, yes. The Kawasaki Z900RS isn't perfect nor does it claim to be, but it has something few bikes offer today: authentic personality, unique character, and pure sensations. If you're looking for a bike that excites you every time you ride, with impeccable retro aesthetics and balanced performance, the Z900RS is hard to beat.

Moreover, thanks to its timeless design, it will remain attractive for many years. A bike to enjoy the journey without hurry and with plenty of style.
