Best for
Built purely for motocross and cross-country racing on dirt tracks, not for street or commuting use.
Built for
A high-strung, revvy two-stroke that rewards aggressive riding, quick gear changes, and an active body position with sharp, flickable handling.
Not ideal for
Not suitable for riders wanting a comfortable, relaxed, road-going or touring motorcycle, or anyone seeking passenger capability or long-distance comfort.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

Will it fit you?

Worked out in your browser - nothing is sent to us
At 958mm, a rider of 68.9" with a 31" (estimated) inseam will not reach the ground comfortably on the 2024 KTM 150 SX, with a cramped knee angle of around 85 degrees and an upright riding position.

Assumes about 30mm of suspension sag once seated. This is an approximation from category-typical geometry, not a measurement of this bike or of you - sit on one before you buy.
