A True Streetbike

Performance for the streets

dependable, comfortable, nimble motorcycle that also delivers genuine Suzuki high-performance. It is made to handle city traffic jams while commuting to work during the week. And it is also an exciting motorcycle ready for fun rides into the countryside or even a track ride on weekends.       

New GSX-S Engine

There is a science to building high-performance engines and the GSX-S125's single cylinder, liquid cooled, DOHC (Double Over Head Cam) is a perfect example of how to make a lot of power out of a very efficient and compact power plant. This power combines with strong torque and exceptional fuel economy, to create an engine worthy of the GSX-S marque, it powers the GSX-S to great performance on the streets and a lot more.

All New Chassis

The chassis design of the GSX-S125 is light and compact, giving the rider ultimate control on the streets for a fast and agile ride. For a street bike low weight is key, this helps deliver a bike with responsive and rewarding handling as well as added confidence on the street.

Lightweight ABS

The Anti-lock Brake System (ABS) is the latest Bosch ABS 10 base unit, which is the lightest and most compact two-channel ABS system on the market.¹ The sporty-looking petal-design 290mm front disc works with a dual-piston caliper and the 187mm petal-design rear disc works with a single-piston caliper, both delivering excellent braking performance.

Light Aluminium Wheels

Contributing to the bikes low weight are the 10 spoke cast aluminium wheels. Having light weight wheels helps ensure great handling, for a ride that’s fun and a machine that goes exactly where you want it to. The slim design of the spokes also adds to this GSX-S’s aggressive street looks, along with the sporty petal type brake discs front and rear.
