Best for: Built purely for motocross racing and off-road riding, excelling on dirt tracks, jumps, and rough terrain rather than pavement use.
Built for: A high-strung, four-stroke single that rewards aggressive riding with sharp handling, strong mid-range punch, and razor-quick direction changes.
Not ideal for: Not suitable for commuting, touring, passengers, or riders seeking a comfortable, low-maintenance street-legal machine.
