Rider Profile
| Best For | This machine rewards intermediate to experienced riders who are comfortable with a track-focused riding position and sharp, immediate responses. |
| Purpose | Built as a sharpened, single-seat special edition of the RS 660, it exists primarily for spirited cornering, trackday laps, and showcasing lightweight sportbike engineering. |
| Rider Fit | Its low, committed sportbike ergonomics and firm suspension demand a fit rider willing to tolerate wrist and wrist load on the street in exchange for cornering precision. |
| Character | It behaves like a scalpel rather than a hammer, favoring quick direction changes, high-revving mid-capacity twin punch, and confidence-inspiring feedback over outright brute power. |
| Not Ideal For | It is not a good fit for new riders, those seeking upright comfort, passenger-friendly touring, or anyone planning to ride off paved roads. |
