Rider Profile

Best ForBest suited to riders with at least some off-road or trials experience, as the tall seat height and light, nimble chassis reward confident standing-up riding technique.
PurposeThis is a dedicated trials-style off-road bike built for tackling technical terrain, obstacles, and tight, slow-speed maneuvering rather than any road-going or high-speed use.
Rider FitThe low dry weight of around 103 kg makes it easy to muscle around and pick up, but the tall 930 mm seat height demands decent leg length or confidence balancing on tiptoes.
CharacterA light, flickable single-cylinder trials machine with long-travel inverted forks and a mono-shock rear, designed to shrug off rocks, roots, and steep climbs with agile, playful handling.
Not Ideal ForNot a fit for riders wanting a comfortable daily commuter, a passenger-friendly bike, or anything resembling sustained highway touring speed and comfort.
