Best for
Built specifically for tight, technical off-road terrain like trails, woods, and enduro-style trails rather than any street use.
Built for
A light, snappy, high-strung 2-stroke enduro weapon that rewards aggressive, active riding and precise clutch and throttle control.
Not ideal for
This is not the right bike for commuting, highway travel, carrying a passenger, or riders wanting a plush, low-maintenance ride.

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

At 960mm, a rider of 68.9" with a 31" (estimated) inseam will not reach the ground comfortably on the 2021 KTM 150 XC-W, 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.
