Suzuki GSX-S 125: generations, engine and what to check when buying used
The Suzuki GSX-S 125 is a 125 cm³ 'naked' class motorcycle introduced in 2017, aimed at young riders. We look at its features, generations and what to check before buying used.
GSX-S 125 in brief
The GSX-S 125 is styled after the larger GSX-S models — aggressive looks, compact frame and a comfortable riding position. It's designed for young and novice riders.
It's lightweight, economical and perfect for city riding. With a 125 cm³ engine, it can be ridden with an A1 or B category license, depending on local regulations.
Which generation to choose
Early GSX-S 125 models met Euro 4 standards, while newer ones comply with Euro 5. Differences mainly involve emissions regulations and minor updates.
Since the model has seen only minor changes, choose based on condition and service history. Newer models generally have lower mileage.
Engine and gearbox
The engine is a liquid-cooled, four-stroke, single-cylinder, 125 cm³ unit with power limited to the A1 category (11 kW). It's economical and well-suited to urban environments.
The gearbox is a six-speed manual, easy to operate. The motorcycle typically comes with ABS and an LCD instrument panel.
What to check when buying a used GSX-S 125
Check the engine start-up, clutch engagement and gear shifting. Inspect the chain, sprockets, brakes and tyres, as young riders often ride aggressively.
Check the plastics and frame for any damage from a fall. Ask for the service history and ensure the documents are in order.
