The GSX-S125 is the little "princess" of the roads. Equipped with great agility, reliability and performance worthy of the best Suzuki, it also sports a modern, sporty design. It is designed both to tackle city traffic jams and to have fun on suburban roads, with snappy acceleration and great range thanks to low fuel consumption.
Its responsive engine, latest technology, easy ride and sporty styling will make you proud to have a GSX-S125 in your garage.
The liquid-cooled 125cc DOHC four-valve engine of the GSX-S125 could be used as a college textbook, an example of how to develop top performance with a compact and efficient engine. The goals of Suzuki engineers were combustion efficiency, engine balance and fuel economy.
There is a distinct connection between the GSX-S125 and the GSX-R series. In fact, both engines adopt a super-square design, with an increased bore and reduced stroke, and boast a bore-to-stroke ratio of 1.501:1 for the GSX-S125 and 1.576:1 for the GSX-R600, respectively.
The high bore size (62 mm) allows the housing of two 24 mm diameter intake valves, while the exhaust valve diameter measures 21 mm. Due to the engine size, the shape of the combustion chamber has been improved so as to increase the compression ratio, overall performance and range.
I cilindri sono costruiti nella fusione del carter superiore e sono lavorati con un rivestimento di nichel-fosforo-silicio-carbonio denominato SCEM (Suzuki Composite Electrochemical Material), sviluppato eccezionalmente dal reparto corse Suzuki. Grazie a questo trattamento è possibile ridurre l'attrito e migliorare il trasferimento di calore così come la durata delle fasce.
Il sistema di raffreddamento a liquido è dotato di un radiatore maggiorato che aiuta a mantenere il motore alla temperatura ottimale in modo da erogare performance costanti, massimizzando l'efficienza di combustione e l’autonomia.
