Rider Profile

Best ForBest suited to riders with at least some prior two-wheel experience, as the tall seat height and light, flickable chassis reward confident bike control.
PurposeBuilt for trail riding, technical off-road tracks, and light enduro use rather than sustained road speed or highway travel.
Rider FitThe tall 900mm seat height and narrow, lightweight frame favor taller or more agile riders comfortable standing on the pegs.
CharacterA nimble, no-frills dirt-focused single suited to riders who enjoy technical terrain over outright power or long-distance cruising.
Not Ideal ForNot a good fit for riders wanting highway comfort, passenger touring, or high-speed road performance.

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

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.
