Rider Profile
| Best For | This is a supermoto built for experienced riders who are already comfortable with a tall, light, single-cylinder machine that demands active input. |
| Purpose | It exists purely to carve up tight tarmac circuits and technical mixed-surface courses with razor-sharp direction changes, not to cover distance or haul gear. |
| Rider Fit | The tall 898mm seat height, minimal weight at 109.3kg, and aggressive ergonomics reward a fit, confident rider who can move around the bike and manage a punchy single-cylinder power delivery. |
| Character | Expect an explosive, visceral character with instant throttle response, flickable handling, and a chassis that thrives on aggressive lean angles and hard braking into corners. |
| Not Ideal For | This bike is not for beginners, commuters, passengers, or anyone seeking comfort, wind protection, or long-distance touring capability. |
