Highly rigid perimeter frame purpose-built for the 125 cm³ class

The all-new steel perimeter frame was purpose-built for the 125 cm³ class. Its high rigidity, compact size and light weight offer excellent handling qualities and contribute to easy manoeuvrability. A combination of form and function, the frame was also designed to be easy to grip with the legs, offering superior chassis control to the rider.

Big-bike FI system

The KLX125 features a big-bike style FI system (where fuel pump, injector and throttle body are all separate pieces). This type of system reduces the chance of air ingestion, making it ideal for spirited sports riding.
