Rider Profile

Best For	Best suited to riders with at least some off-road or enduro experience, as the tall seat, light chassis, and firm suspension reward confident standing-up riding.
Purpose	Built primarily for trail riding, technical off-road terrain, and enduro-style competition rather than road commuting or long-distance travel.
Rider Fit	The very low dry weight and tall 900mm seat height make it easy to flick around but demand decent leg length and some physical fitness for standing control on rough ground.
Character	A lightweight, purpose-built enduro machine with premium off-road components like Marzocchi forks and Galfer brakes, favoring nimbleness and control over outright speed or comfort.
Not Ideal For	Not a good fit for riders wanting a comfortable highway cruiser, a passenger-friendly bike, or strong straight-line performance.
