Rider Profile

Best ForThis is a quirky prototype/concept quad-like machine with a low-powered single-cylinder engine, best suited to riders who want a novelty low-speed experience rather than performance, and note the specs suggest an ATV-style vehicle with double wishbone fro
PurposeBuilt as a concept vehicle with modest 18.77hp output and a top speed of just 82 km/h, it's intended for slow, exploratory or promotional use rather than serious transportation or sport riding.
Rider FitAt 206kg dry weight paired with weak power output, the physical demands are more about maneuvering a heavy, underpowered machine at low speeds than handling dynamic performance.
CharacterIt has an experimental, oddball character typical of a concept-stage vehicle that never saw full production, offering curiosity value over real-world capability.
Not Ideal ForThis is not for riders seeking genuine speed, long-distance touring comfort, aggressive cornering, or off-road capability given its low power-to-weight ratio and limited top speed.
