The Soul of the Z1 x Latest Performance for a Huge Hit! The Reason Kawasaki's "Z900RS" Continues to Sell

Since its debut in December 2017, Kawasaki's neo-classic model "Z900RS" has enjoyed overwhelming popularity in the large motorcycle market. The styling, reminiscent of the legendary Z1, combined with modern riding performance and equipment at a high level, has captured the hearts of many riders. This article examines the background of its success from both design and performance perspectives. It also discusses the evolution of the new model and future trends with the emergence of the rival "CB1000F/SE".

The Z900RS is an Homage to the Legendary Z1

First, let's briefly review the Z1, which served as the motif for the Z900RS.

The Z1, released in 1972, was a globally successful sports model affectionately known as the "900 Super Four." The nickname became more famous than the official model name, as many fans referred to it by its model designation.

At the time of the Z1's release, large-displacement & high-power models were popular worldwide. In particular, Honda's "Dream CB750 Four," released in 1969, was a huge hit due to its high performance, featuring the world's first commercially available air-cooled inline-four engine.

It was in this era that Kawasaki introduced the Z1 as a global strategic model. It was equipped with a 900cc air-cooled inline-four engine, producing a then-impressive 82 PS. Its sleek form, including the teardrop-shaped fuel tank, also contributed to its popularity, and it took the world by storm with its stylish design and high-performance ride.

The Z900RS, a neo-classic model with a style inspired by the Z1, was released in December 2017, as mentioned earlier. It adopts a classical style reminiscent of the Z1, such as the teardrop-shaped fuel tank and the bullet-shaped dual meters. The first-generation model's engine was a 948cc liquid-cooled inline-four producing 111 PS, and it achieved stable riding through features like traction control.

Furthermore, equipped with the latest technology such as a multi-function LCD panel and LED headlights, it has gained significant support as a model that can be enjoyed in various scenes, from street riding to touring and sport riding.

The New Model Upgrades the Engine and More

The Z900RS is now drawing attention with its new model, released in February 2026, marking its first full model change in approximately 8 years.

The new model retains the well-regarded exterior style almost unchanged, with a significant overhaul of the internal components, including the engine.

Firstly, the engine, while maintaining the same displacement, is a new design. Its maximum output has been increased to 116 PS, and it complies with the latest Euro 5+ emission regulations, further improving its environmental performance.

Additionally, the electronic control system has been further evolved. Equipped with ETV (Electronic Throttle Valve), it inherits the direct driving feel of the previous model while improving operability in the low to mid-rpm range. In the high-rpm range, it delivers powerful and sporty characteristics, and sound tuning has been applied to allow riders to enjoy an exhilarating exhaust note.

Furthermore, it is equipped with a "6-axis IMU" that combines sensors such as acceleration and angular velocity sensors. New rider support technologies, such as the "KQS (Quick Shifter)" compatible with upshifts and downshifts, have been incorporated, realizing even more refined ride comfort and convenience.

The current model lineup includes the "Z900RS SE," a premium grade equipped with Öhlins rear suspension and Brembo brakes. There is also the "Z900RS Cafe," which features a front cowl, low-position handlebars, and a dedicated seat, offering a style reminiscent of classic cafe racers. Additionally, a "Z900RS Black Ball Edition" is available, featuring a blacked-out finish on various parts of the standard specification.

The prices (including tax) are 1,529,000 yen for the Z900RS Black Ball Edition, 1,540,000 yen for the Z900RS Cafe, and 1,837,000 yen for the Z900RS SE.

Reproducing the Z1 Image from the Fuel Tank to the Engine

One of the reasons the Z900RS is supported by so many fans is the meticulous design of each part. For example, the teardrop-shaped fuel tank, the rounded tail cowl, the side covers, and the bullet-shaped dual meters all evoke the Z1 of yesteryear. This has been a major appeal of the Z900RS, unchanged from the first generation to the current model.

The bullet-shaped dual meters also create a great atmosphere.

Furthermore, the engine, like the Z1, is a 900cc class inline-four. Although liquid-cooled, it features beautiful fins to create a form reminiscent of old air-cooled engines. The current model is also equipped with a megaphone-type new muffler, updating the retro exterior while contributing to a powerful exhaust sound.

In addition, the front and rear 17-inch cast wheels feature a design that evokes the spoke wheels used on the Z1. The seat also uses a classic tuck roll type, balancing detailed design with ease of use.

The Meticulous Body Colors are Also a Secret to its Popularity

A significant feature of the Z900RS is the adoption of colors that pay homage to the popular body colors of the Z1 on parts like the fuel tank.

For example, the "Fireball (Hinotama)" color, with orange accents on the tank. This is the quintessential Z1 color, and it has been adopted on the first generation (2018 model) released in December 2017, the Z900RS 50th Anniversary model released on February 1, 2022, and the latest Z900RS SE (2026 model).

While they may look like the same color at first glance, the actual colors and painting methods differ for each generation.

For instance, the "Candy Tone Brown x Candy Tone Orange" of the first-generation model. This is a pattern combining brown as the base with orange applied over it.

In contrast, the "Metallic Spark Black" adopted by the new Z900RS SE has a slightly different hue compared to the first generation, with a matching of black and orange.

Additionally, the 50th Anniversary model, celebrating 50 years of the Z series, features "Candy Diamond Brown." This color utilizes a special painting process developed exclusively for the 50th Anniversary. It is said to achieve a lustrous and deep finish by applying candy colors in layers using a unique technique.

Meanwhile, the "Candy Tone Blue" adopted for the Z900RS (2022 model, standard specification) released in September 2021 is based on the color used on the 1975 Z1. It pays homage to the color affectionately called "Aodama" by enthusiasts.

In addition, the "Yellow Ball" color has been adopted for the Z900RS SE (first generation SE) released on November 21, 2021, and the Z900RS Yellow Ball Edition released on July 15, 2023. While the Fireball color is famous for the Z1, the Fireball was mainly sold in the North American market, whereas the Yellow Ball was more common in European specifications.

Furthermore, the "Vintage Lime Green" adopted for the Z900RS Cafe (first generation) released on March 1, 2018, is said to be an homage to the "Lawson Replica" of the 1980s.

The first-generation Z900RS Cafe, released on March 1, 2018, features "Vintage Lime Green."

Currently, the Z900RS Cafe features a rainbow line graphic on its fuel tank, paying homage to Kawasaki's legendary "Mach Series" models. The "KAWASAKI" logo in the center uses a transfer film, allowing the underlying body color to show through, creating a unique presence.

As such, successive Z900RS models have adopted not only the representative body colors of the Z1 but also rare colors, reproduced with modern technology. The beautiful finish of the paintwork creates a special feeling unlike other models, which is also a major appeal.

How Will It Fare Against the Strong Rival CB1000F?

As can be seen from the above, the Z900RS is a model that has adopted a form and colors meticulously recreated to resemble the Z1. Its high degree of faithfulness to the original model (Z1), while still feeling modern, is a significant attraction.

Some manufacturers might have a mindset of not wanting to release a bike that simply imitates an old model, given that it's a new model (this is purely the author's speculation). In that regard, Kawasaki's approach to neo-classic models feels refreshingly straightforward. This is likely what strongly appeals to the sentiments of many fans who wish to ride again the bikes that were popular in their youth. The fact that it still reigns supreme in new large motorcycle sales figures, about 8 years after its release, is likely due to its product appeal, which has masterfully captured such user psychology.

The perfect balance of vintage-inspired design and excellent riding performance is the Z900RS's greatest strength!?

Honda's new "CB1000F/SE," which is currently attracting significant attention, appears to adopt a similar approach. This model is designed with the legendary "CB750F" from the late 1970s to the 1980s, and its export version, the "CB900F," as its motif. In particular, the steel fuel tank has a "steel-like surface expression," evoking the classic CB750F while balancing hardness and softness for a modern taste.

It is powered by the engine from the 2017 "CBR1000RR" super sport model, producing a maximum output of 124 PS. By balancing torque and power characteristics in the low and mid-speed ranges at a high level, it achieves characteristics that are easy for a wide range of riders to handle.

Moreover, the price (including tax) is 1,397,000 yen for the standard CB1000F and 1,595,000 yen for the CB1000F SE with a front cowl. The relatively reasonable pricing is likely to be a significant point in competing with the reigning king, the Z900RS.

However, the CB1000F/SE experienced recalls shortly after its release in January 2025 and March 2026 (due to potential engine failure from piston defects, etc.), leading to temporary suspension of shipments and production. This was a setback for a model that was drawing attention as a strong competitor to the Z900RS. Rumors suggest that production and shipments will resume sequentially soon, but the future remains to be seen. It will be interesting to watch how the CB1000F/SE makes its comeback and challenges the Z900RS's throne as the king of large motorcycles.
