Rider Profile

Best For	Best suited to intermediate or experienced riders who can manage a light, torquey single-cylinder machine with sharp, direct responses.
Purpose	Built for supermoto thrills, tight city streets, and flicking through corners rather than covering long distances.
Rider Fit	A low dry weight and tall, narrow seat favor riders who are comfortable standing or shifting weight actively and don't mind a firm, sporty riding position.
Character	A raw, punchy single-cylinder brawler that rewards aggressive, playful riding with immediate throttle feedback and razor-sharp handling.
Not Ideal For	Not a good fit for riders seeking plush comfort, wind protection, or a smooth machine for long highway journeys or two-up touring.
