Rider Profile
| Best For | Best suited to intermediate to experienced riders who are comfortable with a light, quick-steering, high-revving single-cylinder machine that demands active input. |
| Purpose | Built for supermotard fun: sharp cornering, tight tarmac twisties, and flickable city or track riding rather than covering distance. |
| Rider Fit | Its very low dry weight around 105 kg and tall 900 mm seat height suit riders of average to above-average height who want an agile, standing-friendly bike, though the reach to the ground may challenge shorter riders. |
| Character | A punchy, minimalist, race-bred single that rewards aggressive, playful riding with immediate direction changes and strong braking feel from its high-spec suspension and brakes. |
| Not Ideal For | Not a good fit for riders wanting long-distance comfort, wind protection, passenger capability, or a smooth, low-maintenance commuter experience. |
