Rider Profile

Best For	Best suited to intermediate or experienced riders comfortable with a tall, torquey, top-heavy-feeling single-cylinder motard.
Purpose	Built for sharp, playful cornering and supermoto-style thrills on twisty tarmac rather than outright top speed or long-distance cruising.
Rider Fit	The tall 900mm seat height and light 152kg dry weight favor taller or more agile riders who can manage a firm, upright, aggressive riding stance.
Character	A raw, punchy, single-cylinder hooligan bike that rewards an energetic riding style and thrives on flickable handling over refinement.
Not Ideal For	Not a good fit for riders seeking plush comfort, pillion-friendly touring, or a smooth, vibration-free highway cruiser experience.
