The KDX 125SR of 1997-98 is a 124 cc two-stroke trail bike, offered in a learner-legal 12 bhp form and in a 24 hp version. Reviewers found it easy to ride on back roads and in town, with good damping and a tight turning circle. Its weak points were high-speed vibration, modest power for fast roads and softer braking feel.
