Rider Profile
| Best For | Best for experienced riders; the 140hp inline-four and aggressive power delivery are a handful for novices despite friendly ergonomics. |
| Purpose | Aggressive street naked built for spirited backroad blasts, canyon carving and confident urban riding with a big-bore punch. |
| Rider Fit | Upright, sporty stance with 815mm seat, wide bars and firm sportbike suspension. Roomy for its class but leaned slightly forward. |
| Character | Muscular, hooligan super-naked with a howling inline-four, sharp styling and eager throttle. Refined yet raw and full of attitude. |
| Not Ideal For | Not for beginners, dedicated long-haul tourers wanting wind protection, or anyone seeking off-road ability or a laid-back cruiser. |
