Engineered by Suzuki for the naked motorcycle segment, the 2017 Suzuki GSX-S125 features a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 62.0 x 41.2 mm (2.4 x 1.6 inches) with a 11.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Suzuki archive, this model family spans 7 indexed model years from 2017 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
