Rider Profile

Best ForBest suited to intermediate to experienced riders comfortable with a tall, light, torquey single that demands active body input.
PurposeBuilt primarily for serious off-road enduro riding with enough refinement to handle occasional road and commuting duty.
Rider FitThe tall 910mm seat height and firm long-travel suspension favor taller or physically fit riders confident standing on the pegs.
CharacterA raw, punchy big-bore single that rewards aggressive, hands-on riding with sharp handling and minimal weight to manage.
Not Ideal ForNot a good fit for riders wanting plush comfort, passenger-friendly touring, or a low, easy-going city commuter.

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.
