Does the KTM 125 SX fit you?
The KTM 125 SX (2026) has a 958 mm seat height. As a rule of thumb, riders with an inseam around 96 cm — roughly 204 cm (6'8") tall — can plant both feet flat at a stop. Around 90 cm inseam you'll be on the balls of your feet, and shorter riders will tiptoe. Enter your own height and inseam in the simulator above to see exactly how you reach the ground on the KTM 125 SX.
Riding position
As a motocross motorcycle, the KTM 125 SX puts you in an upright, neutral riding position. The simulator scores the exact knee, hip, and elbow angles for your body so you can see how relaxed or aggressive the reach to the bars and pegs will feel.
What is the KTM 125 SX best for?
The KTM 125 SX is best suited to all-round road riding.
Fit figures are rules of thumb (flat-foot inseam ≈ seat height); the simulator gives your exact reach and joint angles. Braking is an estimate from wet weight and wheelbase on a dry road.
