Rider Profile

Best For	This is a purebred late-1980s enduro built for competent off-road riders, not beginners intimidated by tall seat height and light, twitchy handling.
Purpose	It exists for trail riding, enduro competition, and technical off-road terrain rather than any street or highway use.
Rider Fit	The tall 940mm seat height, narrow dirt-bike ergonomics, and 128kg dry weight demand decent rider fitness, leg length, and standing-up riding skill.
Character	It's a lightweight, high-revving, liquid-cooled single with premium WP suspension, giving it a nimble, aggressive, hardcore off-road personality typical of boutique 1980s enduro machines.
Not Ideal For	It's not for riders wanting comfort, passenger capability, long-distance touring range, or paved-road performance.
