How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A sharp, minimalist streetfighter built for backroad carving, spirited city blasts and quick B-road runs rather than long-haul mileage.
- Built for
- 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.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
