Ready to rock the streets

There’s a science to building high-performance engines, and the GSX-R125’s DOHC engine could be used in a university textbook as an example of how to make a lot of power out of a very efficient and compact powerplant. The engine makes high horsepower for its size and produces generous torque, delivering strong, effective power across a broad rpm range.

There is a connection between the GSX-R125 and the race-proven four-cylinder GSX-R600 sold around the world, because the GSX-R125’s single cylinder is almost one-quarter of a GSX-R600. Although Suzuki engineers experimented with different bore and stroke figures to find the most efficient combination for the GSX-R125, the two engines both use an over-square design, with a larger bore and a shorter stroke, and have a similar bore x stroke ratio, 1.576:1 for the GSX-R600 and 1.505:1 for the GSX-R125.

Key-Less Ignition System

The GSX-R125 features a convenient key-less ignition system, and the rider can start the engine as long as the compact key is close enough in proximity to the motorcycle.

Which means the rider doesn’t have to fumble around to retrieve the key from their pocket or backpack.

A button on the remote control also activates an answer-back function, causing the indicators to flash and making it easier to find the GSX-R125 in a crowded car park.
