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

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 put it through a tough test: more than 2,500 km from Austria to Montenegro, covering all kinds of roads—from fast highways to winding mountain passes, and surfaces in various 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 grabs attention about the Kawasaki Z900RS is its design. The Japanese brand has skillfully captured the spirit of 70s motorcycles without sacrificing current standards of quality and finish.

The fuel tank particularly stands out. Kawasaki chose a meticulous and authentic paint job, steering clear of cheap solutions like stickers. Additionally, features like the dual analog clock instrumentation, complemented by a small digital screen in the center, add to that retro experience without sacrificing modern practicality.

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

In summary, in terms of design and build, the Z900RS scores highly, demonstrating a harmony between classic and modern, with materials and finishes worthy of a premium motorcycle.

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

The power delivery is progressive and predictable, with enough mid-range grunt to avoid constant gear shifts. Meanwhile, revving it up towards the higher range is an auditory delight, thanks to a well-tuned exhaust that adds character to each acceleration without becoming bothersome on long rides.

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

One area where the Z900RS could improve is its weight: at 216 kg, it's not particularly light. While this is hardly noticeable in motion due to the excellent chassis balance, it can feel somewhat 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 at a leisurely pace.

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 Z900RS suspension doesn't offer full adjustability and is fairly basic. The inverted front fork (USD) doesn't allow for adjustments, and at the rear, the mono-shock offers only basic preload adjustment.

In contrast, the Z900RS SE version includes higher quality, adjustable suspension, offering full adjustability in both the front fork and the 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 more demanding riding. Conversely, the Z900RS SE is the better option if you especially value being able to adapt the bike to different riding styles or routes.

On well-paved roads, the Z900RS feels stable, composed, and predictable. It's not an ultra-light or extremely agile bike, but it does inspire great confidence when tackling fast corners or twisty tracks securely.

When the tarmac deteriorates, the suspension shows its limits. It absorbs moderate irregularities without issues, but on particularly rough or bumpy roads, it quickly becomes clear that it's not an adventure bike nor does it aim to be. Nevertheless, overall comfort remains acceptable even on long rides.

Although it's not a true sport-tourer, the relaxed ergonomics, along with a plush and comfortable seat, allow for long journeys without much fatigue.

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

Up front, it features dual 300 mm discs with radial calipers, while the rear is fitted with a single 250 mm disc. This setup provides enough power to safely bring the bike to a stop in everyday and relaxed riding situations. However, if you're looking for more robust braking, especially at high speeds or when riding aggressively on mountain roads, you'll notice some weaknesses.

The main critique is the 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 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 strong and late braking into corners, you'll clearly notice the inertia. While not severe or dangerous, those accustomed to lighter, sportier bikes will miss a bit more braking punch.

A simple and effective upgrade would be to install braided brake lines and higher-performance brake pads, which would significantly improve the feel and effectiveness during intense braking. All of this comes standard in the Z900RS SE version.

The Kawasaki Z900RS doesn't stand out for being the fastest, lightest, or most technologically advanced, but it shines brightly in something many modern bikes have forgotten: delivering an authentic and sensation-filled experience.

You sit more 'on' the bike than 'in' it compared to the standard Z900. The riding position is well-thought-out, with a high and wide handlebar, comfortably positioned 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 each kilometer, not necessarily to devour them in record time.

In the city, its behavior is decent, although, as mentioned, its weight can be a downside when navigating heavy traffic. Still, the engine's smoothness at low revs and a reasonably tight turning radius help make urban riding not excessively uncomfortable.

On open roads and fast corners is where the Z900RS truly shows its best side: the chassis stability, engine smoothness, and evocative sound create a unique experience. The bike feels predictable and secure, inviting you to enjoy the ride 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 is logical and normal, the lack of aerodynamic protection limits comfort at high speeds over prolonged periods. To solve this 'problem,' you can always install a small screen for a few bucks 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:

The Good:

• Design and Finish: Excellent quality, attention to detail, and a perfectly executed retro aesthetic.
• Engine: Smooth, powerful, and with an addictive sound. Offers enough grunt for any situation.
• Comfort: Comfortable and ergonomic riding position for long trips or daily use.
• Chassis: Stable, balanced, and predictable, instills 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 Improved: Good overall performance, but they lack a bit more bite and firmer feel in sporty riding.
• Limited Technology: While simplicity is part of its charm, some riders may miss more advanced electronic aids.

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

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