Rider Profile
| Best For | For intermediate to experienced riders comfortable with a tall, raw big-single; not ideal for beginners due to seat height and abrupt power delivery. |
| Purpose | A street supermoto built for hooligan fun-carving canyons, slicing city traffic, wheelies and backroad hustling on sticky 17-inch road rubber. |
| Rider Fit | Tall 900mm seat, narrow chromoly chassis, upright bars and long-travel WP suspension. Light at 149kg dry but vibey single and thin seat punish long stints. |
| Character | Rowdy, minimalist, and full of attitude-a punchy thumper that thrives on flicking through corners and pulling stunts rather than covering miles. |
| Not Ideal For | Not for tourers, two-up riders, short inseams, or anyone wanting smooth refinement, long-range comfort, or true off-road ability. |
