The KDX 125 is a 124 cc two-stroke dual-purpose bike sold from 1990 to 1992. Its strengths are its trail ability, with a tall seat, tight turning circle and suspension that copes well with rough ground. It was less suited to fast roads, where the restricted engine and high-speed vibration limited it.
