Overview - Suzuki GSX-8S 2023 vs Honda CB650R 2021

The Suzuki GSX-8S 2023 and the Honda CB650R 2021 are both naked bikes with similar technical specifications. However, there are several key differences between the two models.

In terms of engine power, the Honda CB650R has a higher output with 95 HP compared to the Suzuki GSX-8S's 83 HP. This gives the Honda CB650R a slight advantage in terms of acceleration and top speed. However, the Suzuki GSX-8S compensates for this with its higher torque of 78 Nm, providing better low-end power and overall performance.

Both bikes feature in-line engines with fuel injection systems and liquid cooling. They also have similar suspension setups, with upside-down telescopic forks at the front and swing arms with monoshock absorbers at the rear. The suspension on both models can be adjusted for preload, allowing riders to fine-tune the bike's handling to their preferences.

In terms of strengths, the Suzuki GSX-8S offers a full-grown and high-quality overall concept with a high-torque engine and stable handling. It has a great naked bike riding position, good ergonomics, and a very good seat.

In terms of weaknesses, the Suzuki GSX-8S has a slightly heavier weight compared to other bikes in its class, and its quickshifter and gearstick require more operating force than usual. The ABS controls on the GSX-8S are also described as being very defensive, and the engine lacks rev reserves upwards. The Honda CB650R, on the other hand, has limited space for tall riders, mediocre equipment, a relatively chubby design, and lacks punch from the rev range.

Overall, both the Suzuki GSX-8S 2023 and the Honda CB650R 2021 have their own strengths and weaknesses. The choice between the two models ultimately depends on the rider's preferences and priorities, such as power, handling, rider assistance systems, and fuel efficiency.

Pros and Cons in comparison

Pros and Cons in comparison

Suzuki GSX-8S 2023

Suzuki GSX-8S 2023

For years, Suzuki was the brand that offered nice bikes at a good price/performance ratio. With the Suzuki GSX-8S, the brand is much more self-confident. It presents itself as high-quality, mature and places itself at the top of a hard-fought class. The unspectacular performance data and the relatively high weight tarnish the picture only briefly. During the test rides, the Suzuki was completely convincing. A really good motorbike.
