| Purpose | Built for spirited street riding and twisty back roads where its light weight and strong midrange power can be fully exploited. |
| Rider Fit | The low-ish seat height and compact, upright naked-bike stance suit a range of body sizes, though the firm sporty suspension favors riders comfortable with a slightly aggressive posture. |
| Character | A raw, characterful Italian streetfighter that rewards confident throttle input with an engaging, muscular V-twin feel and razor-sharp handling. |
| Not Ideal For | Not ideal for riders seeking long-distance comfort, wind protection, or a plush, relaxed touring experience. |
