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.
