A True Sports bike

GSX-R125, excellent power-to-weight ratio, torque-to-weight ratio and acceleration, plus nimble handling and great fuel economy in the 125cc class.

The Suzuki GSX-R line has defined sports bike performance for over 30 years, with more than a million sold worldwide. So the dedicated Suzuki engineers who have devoted their lives to the GSX-R take their responsibilities very seriously. Meet the revolutionary Suzuki GSX-R125, with excellent power-to-weight ratio and acceleration

Sporty Engine

The objective is sporty engine performance, character, combustion efficiency and fuel economy. This power combined with torque and balanced with fuel efficiency creates an engine worthy of the GSX-R marque. The GSX-R125 engine displaces an actual 125cc from a 62mm cylinder bore and a 41.2mm piston stroke. The larger bore makes room for two 24mm intake valves and two 21mm exhaust valves, set upright at narrow angles to improve the shape of the combustion chamber, increasing the compression ratio, performance and fuel economy.

Advanced Electronic Fuel Injection

The GSX-R125 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-R125 has a 32mm throttle body.

Key-less ignition System

The GSX-R125 features a convenient key-less ignition system. This means the rider can start the engine without putting the key in the ignition if the compact key is close enough to the motorcycle. Therefore, the rider doesn’t have to fumble to retrieve the compact key from a pocket or backpack.
