Performance Profile & Rider Fit
Best For
Rider Profile
| Best For | Best for intermediate to experienced riders who enjoy a lively single-cylinder character; the tall seat and punchy delivery reward confident, active riding. |
| Purpose | A sharp, minimalist streetfighter built for backroad carving, spirited city blasts and quick B-road runs rather than long-haul mileage. |
| Rider Fit | Very light (148kg dry) with a lofty 865mm seat and upright, roomy naked-bike stance; slim, flickable and easy to muscle for taller riders. |
| Character | A single-cylinder hooligan: torquey thumper punch, razor-sharp handling and no-nonsense KTM attitude packed into a featherweight trellis chassis. |
| Not Ideal For | Not for tourers, two-up cruisers, or riders wanting all-day comfort, a low seat, or smooth long-distance highway manners. |
