Performance Profile & Rider Fit

Rider Profile
| Best For | This is a big-bore open-class sportbike best suited to experienced riders who are comfortable with strong power delivery and a committed riding position. |
| Purpose | Built primarily for fast road riding and track days, blending litre-bike power with a slightly more manageable 900cc package. |
| Rider Fit | The high seat height and forward-leaning stance demand a reasonably fit rider and put notable weight on the wrists during slower riding. |
| Character | A raw, aggressive superbike with a strong mid-range punch and a chassis that rewards confident, assertive inputs. |
| Not Ideal For | This is not the right choice for new riders, commuters seeking comfort, or anyone planning long-distance touring or off-road use. |
