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 find out if this bike is more than just its good looks, I decided to put it to the test on a demanding journey: over 2,500 km from Austria to Montenegro, covering all types of roads, from fast highways to winding mountain passes, and various pavement conditions.

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

One of the first things that grabs your attention about the Kawasaki Z900RS is its design. The Japanese brand has masterfully captured the essence of 1970s motorcycles without compromising on current standards of quality and finish.

The fuel tank is a standout feature. Kawasaki chose a meticulous and authentic paint job, steering clear of cheap sticker solutions. Additionally, details like the dual clock analog 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 of its current rivals. The absence of features like a modern TFT screen or advanced electronic aids might disappoint some, but for those seeking a pure and straightforward riding experience that evokes nostalgia, this is more of a virtue than a drawback.

In conclusion, in terms of design and build, the Z900RS scores highly, showing a seamless blend of classic and modern, with materials and finishes worthy of a premium motorcycle.

The heart of the Kawasaki Z900RS is a 948 cc inline-four engine delivering 111 horsepower. 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 grunt (a strong, responsive surge of power) to avoid constant gear changes. At the same time, revving it out to the higher range is a sonic delight, thanks to a well-tuned exhaust that adds character to every acceleration without becoming tiresome on long rides.

Although the six-speed manual gearbox is precise and smooth (not a single miss or problem finding neutral over 2,500 km), an optional quickshifter is missed, which would have complemented the dynamic nature of this bike. However, for purists, this may be irrelevant or even positive.

One area where the Z900RS could improve is weight: at 216 kg, it's not particularly light. While this is barely noticeable in motion due to the excellent balance of the chassis, it can feel somewhat heavy in slow maneuvers or urban traffic.

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

The chassis of the Kawasaki Z900RS is a steel trellis design, effectively combining 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 offer full adjustability, being quite straightforward. The inverted front fork (USD) doesn't allow adjustments, and the rear mono-shock only offers basic preload adjustment.

On the other hand, the Z900RS SE version includes higher-quality, adjustable suspension, offering full adjustment both in the front fork and rear shock, along with premium components like the Öhlins rear shock.

This difference between versions makes the standard Z900RS more limited if you're looking to tweak the dynamic behavior to your personal preferences or for more demanding rides. In contrast, the Z900RS SE is a better choice if you especially value the ability to adapt the bike to different types of riding or routes.

On well-paved roads, the Z900RS feels stable, noble, and predictable. It's not an ultralight or extremely agile bike, but it inspires great confidence to tackle fast bends or twisty paths safely.

When the tarmac worsens, the suspension shows its limitations. It absorbs moderate irregularities without issues, but on particularly broken or bumpy roads, it quickly becomes clear that it's not designed to handle rough terrain like an adventure bike. Still, overall, the comfort is acceptable even on long rides.

Though not a true sport-tourer, the relaxed ergonomics, along with a plush and comfortable seat, allow for long journeys without too much discomfort.

In terms of braking, the Kawasaki Z900RS comes equipped with a system that, while effective, could benefit from some tweaks for 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 enough power to safely stop the bike in any everyday situation and during relaxed rides. However, if you're looking for more robust braking, especially at high speeds or when riding aggressively on mountain roads, you'll notice certain weaknesses.

The main criticism is the feel of the lever. While the radial calipers offer good power and progressiveness, the initial bite could be more direct and firm, meaning the braking force and responsiveness could be improved. Additionally, the ABS, which comes standard, tends to activate a bit earlier than desired during hard braking, reducing precision in more demanding situations.

This behavior becomes more evident due to the bike's weight (216 kg). In hard and late braking into corners, you'll clearly feel the inertia. Although it's not severe or dangerous, those used to lighter, sportier bikes will miss a bit more bite in the brakes.

A simple and effective improvement would be installing steel-braided lines and higher-performing brake pads, which would significantly enhance the feel and effectiveness during intense braking. All of this is included in the SE version of the Z900 RS.

The Kawasaki Z900RS doesn't stand out as the fastest, lightest, or most technologically advanced, but it shines brightly in something many modern bikes have forgotten: offering an authentic and sensory-rich experience.

You sit more "on" the bike rather than "in" it, compared to the standard Z900. The riding position is well-executed, with a high and wide handlebar, comfortably placed footpegs, and a spacious, well-padded 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 disadvantage in heavy traffic. Nonetheless, the engine's smoothness at low revs and a fairly reasonable turning radius make urban riding not excessively uncomfortable.

On open roads and fast bends is where the Z900RS really shows its best side: the stability of the chassis, the engine's smooth power delivery, and its evocative sound create a unique experience. The bike feels predictable and secure, inviting you to enjoy the journey peacefully. Adding to that is its mechanical throttle, not ride-by-wire, providing extraordinary feedback on what's happening with the bike. It's something hard to explain.

On the highway, as expected, the lack of aerodynamic protection limits its comfort at high speeds over prolonged periods. To solve this "issue," you can always install an inexpensive 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 about the Kawasaki Z900RS:
