Rider Profile
| Best For | Suited to new-to-intermediate riders thanks to its light weight, low power, and forgiving handling. |
| Purpose | Built as a nimble, street-biased supermoto for flicking through city traffic and carving tight, twisty backroads rather than covering long distances or going off-road. |
| Rider Fit | Its low 115kg dry weight and narrow supermoto ergonomics make it easy to manage for smaller or less physically strong riders, though the 870mm seat height demands reasonable inseam length. |
| Character | A playful, flickable little street hooligan that rewards aggressive cornering lines and quick direction changes over outright speed. |
| Not Ideal For | Not a good fit for riders wanting highway touring comfort, serious off-road capability, or strong outright acceleration. |
