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.
