Rider Profile

Best For	This is a rare 1988 prototype/concept machine, best suited to experienced riders or collectors comfortable with an unconventional, unproven motorcycle rather than newcomers.
Purpose	Built as an experimental small-capacity V-twin with desmodromic valve control, it was likely intended to showcase engineering ideas rather than serve as a mainstream production commuter or tourer.
Rider Fit	At 190 kg with a modest 42 hp output, it demands moderate physical effort to manage at low speeds but is light enough for confident handling once moving.
Character	It has the character of an intriguing engineering curiosity, blending a compact 350cc air-cooled V2 with exotic desmodromic technology in a lightweight chassis.
Not Ideal For	It is not suited for riders seeking high-speed performance, long-distance touring comfort, or off-road capability.
