Suzuki GSX-S125 2023

The Suzuki GSX-S125 feels more grown-up than the identically constructed GSX-R125. It is slightly wider around the tank and does not need a fairing for a maximum speed of about 120 km/h. Technically, it is identical to the GSX-R, but with higher and wider handlebars and thus a more upright position. Technically, it is identical to the GSX-R, but it is more fun with the higher and wider handlebars and the resulting more upright riding position. A wheelie is pretty easy to do, so you can do without a few km/h of top speed.
