A number board on a motorcycle is a flat panel typically used to display a rider's race number or identification number. It is commonly seen in motocross, off-road, or racing motorcycles. The number board is usually made from durable plastic or other lightweight materials and is mounted on the front of the bike, often attached to the handlebars or front forks. It ensures visibility for race officials, photographers, and spectators during events.
