Rider Profile

Best ForThis is a serious competition enduro machine best suited to experienced off-road riders comfortable with a tall, light, high-strung dirt bike.
PurposeBuilt for enduro racing and technical trail riding rather than commuting or highway travel.
Rider FitThe tall 940mm seat height and minimal wet weight favor taller, fit riders who can stand on the pegs and muscle the bike over obstacles.
CharacterA featherweight, punchy single-cylinder four-stroke with premium suspension that rewards an aggressive, active riding style.
Not Ideal ForNot a good fit for new riders, passengers, long paved journeys, or anyone wanting plush comfort and low maintenance.

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.
