Rider Profile

Best ForFor experienced and competitive riders. The explosive two-stroke power and race-only setup will overwhelm beginners.
PurposeA pure-bred motocross weapon built for racing berms, jumps and rough terrain at full attack on closed circuits.
Rider FitTall 958mm seat, extremely light 99kg dry, long-travel WP AER forks and slim ergonomics. Demands a rider ready to stand and attack.
CharacterFeatherweight, hard-hitting and razor-sharp — a violent, high-revving two-stroke MX machine that lives to be ridden hard.
Not Ideal ForNot for commuting, touring, road riding, passengers or anyone wanting a comfortable, easygoing bike. No lights, no plate.

Feet:

At 958mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2024 KTM 300 SX, with a cramped knee angle of around 85 degrees and an upright riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
