Rider Profile

| Purpose | Designed as a sharp, lightweight streetfighter for spirited commuting, twisty backroads and occasional trackday fun. |
| Rider Fit | A moderate 825mm seat height and slim chassis make it manageable for most riders, though the punchy torque demands confident throttle control. |
| Character | Playful, aggressive and eager to change direction, with a torquey parallel twin that rewards an energetic riding style. |
| Not Ideal For | Not the right choice for riders seeking long-distance comfort, pillion-friendly touring, or serious off-road capability. |
