Rider Profile

Best For	This is a tall, powerful single-cylinder machine best suited to experienced off-road riders comfortable with a rally-bred, top-heavy feel at low speed.
Purpose	Built as a factory rally replica, it's designed for long-distance desert-style off-road adventure riding rather than commuting or track work.
Rider Fit	The 980mm seat height and 162kg dry weight demand a taller rider with good physical strength and confidence balancing the bike standing on rough terrain.
Character	It has a raw, torquey big-single character with hard-hitting power delivery and rally DNA that rewards an aggressive, engaged riding style.
Not Ideal For	This is not the right bike for shorter riders, nervous beginners, or anyone wanting a plush, low-effort commuting or two-up touring experience.
