A True Streetbike
Meet the new lightweight king of the streets, the Suzuki GSX-S125. It has the best power-to-weight ratio and acceleration in the 125cc street sport class.
Performance for The Streets
A 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.
The engineers behind the GSX-R series have been perfecting engines for over 30 years, and this is their latest masterpiece. In the 125cc class the GSX-S125 has the best power-to-weight ratio, the best torque to weight ratio and the
best acceleration. So the rider can enjoy the most fun and excitement, every corner, every straight and every ride. This level of performance is legendary for a GSX-R and now a GSX-S too, but beyond the power and acceleration there
is even more, this engine is also extremely fuel efficient as well, so you can travel further on each tank of fuel before it's time to re-fill.
The engine makes its high horsepower and reaches its generous torque, delivering strong, effective power across a broad rpm range. Aided by an effective liquid-cooling system with a large radiator helps keep the engine at the optimum
temperature, producing consistent performance and maximising fuel efficiency and mileage. And the GSX-S125 comes with a smooth-shifting 6-speed transmission and an electric starter.
The GSX-S125 features advanced electronic fuel injection, which delivers fuel based on what the rider is doing with the twist-grip throttle as well as input from sensors monitoring engine rpm, intake air pressure and temperature, exhaust
oxygen content and coolant temperature. To improve intake efficiency, throttle response, and engine power throughout the rpm range, the GSX-S125 has a 32mm throttle body.
