Rider Profile

Best For	Best suited to experienced riders who are comfortable with a tall, light, torquey single that demands active input and respect for its punchy low-end power delivery.
Purpose	Built for supermoto-style thrills: flicking through tight corners and urban streets with sharp, aggressive handling rather than covering long distances in comfort.
Rider Fit	The tall 910 mm seat height and narrow, top-heavy single-cylinder feel favor taller or more physically confident riders who can manage the bike at low speeds.
Character	A raw, mechanical, and characterful machine with big single-cylinder vibration and torque pulses that reward a rider who enjoys visceral, unfiltered feedback.
Not Ideal For	Not a good fit for riders seeking plush comfort, pillion-friendly ergonomics, or a relaxed long-distance touring experience.
