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.
Petal brake discs front and rear provide superb stopping power. In addition to helping reduce unsprung weight, the wave shapes of the petal discs help clean the brake pads for more efficient braking performance.
With all chassis components were designed specifically for the 125 cm³ class (rather than borrowed from larger-displacement models), the KLX125 has very well-balanced proportions that add to a sharp appearance.
Because its chassis components were designed specifically for the 125 cm3 class, the KLX125 offers a lightweight, compact package which results in a low seat height.
