Best for: Built as a cross-country (X) variant of Kawasaki's motocrosser, it's purpose-made for closed-course off-road racing like hare scrambles and enduro-style events rather than general riding.
Built for: The bike feels light, flickable, and eager to change direction, rewarding an aggressive, attacking riding style over relaxed cruising.
Not ideal for: This is not the right choice for commuting, highway travel, passenger carrying, or riders wanting plush all-day comfort.

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