Rider Profile
| Best For | Approachable for newer riders thanks to light weight and friendly power, yet fun enough to keep experienced hooligans grinning. Tall seat suits taller riders. |
| Purpose | A street supermoto built for carving city streets, backroad hairpins and kart-track laps. Wheelies, stoppies and flickable fun over outright speed. |
| Rider Fit | Very tall 890mm seat and slim, upright motard ergonomics. Featherweight 146kg wet with narrow tank and minimal wind protection. |
| Character | A playful, energetic single-cylinder motard-light, torquy and endlessly flickable. All about grins per mile rather than top-end thrills. |
| Not Ideal For | Not for highway commuters, tourers or two-up riders-tiny 10L tank, buzzy single, no wind protection and a seat too tall for short inseams. |
