Best for: Built purely for motocross track riding and racing, not for commuting, road use, or general recreational riding.
Built for: A lightweight, single-cylinder four-stroke racer with a peaky powerband and razor-sharp handling designed for jumps, berms, and hard acceleration out of corners.
Not ideal for: Not suitable for riders wanting a comfortable daily commuter, a passenger-friendly bike, or a long-distance touring machine.
