Rider Profile

Best For	This is a demanding machine best suited to experienced riders who are comfortable with a light, powerful, and twitchy chassis.
Purpose	Built almost purely for supermoto thrills: flicking between tight corners on tarmac with occasional forays onto light dirt.
Rider Fit	The tall 915mm seat height and firm, aggressive riding position favor taller riders and those with strong core and leg strength for standing and shifting body weight.
Character	A raw, single-cylinder hooligan bike that rewards aggressive, playful riding with immediate, visceral feedback through the chassis and engine.
Not Ideal For	Not suited to riders seeking a comfortable long-distance tourer, a relaxed daily commuter, or a beginner-friendly first bike.
