Rider Profile
| Best For | Best suited to intermediate or experienced riders who are comfortable with a tall, light, quick-turning single that demands active input; note the given specs are for a supermoto and align with the M4 name and category. |
| Purpose | Built for sharp, flickable street and back-road cornering fun rather than long-distance travel or hauling gear. |
| Rider Fit | The tall 870mm seat height and lightweight 133kg dry chassis favor riders of average-to-taller height who can confidently manage a top-heavy stance at a standstill. |
| Character | A punchy, single-cylinder supermoto character that rewards aggressive throttle and brake inputs with immediate, playful responses and minimal rotating mass to fight against. |
| Not Ideal For | Not a good fit for riders seeking high-speed highway cruising, passenger comfort, or serious off-road capability given its street-biased 17-inch wheels and minimal wind protection. |
