Final answer:
Off-highway motorcycles are categorized into motocross bikes, trail bikes, and dual-purpose bikes based on their design and intended use.
Step-by-step explanation:
Off-highway motorcycles are categorized based on their design and intended use. The three main categories of off-highway motorcycles are motocross bikes, trail bikes, and dual-purpose bikes. Motocross bikes are specifically designed for racing on closed off-road tracks with jumps, berms, and obstacles.
They have high-performance engines, long-travel suspension, and lightweight frames. Trail bikes are designed for off-road riding on rough terrains. They have features like larger fuel tanks, electric start, and softer suspension for a more comfortable ride.
Dual-purpose bikes, also known as adventure or enduro bikes, are designed to be used both on and off-road. They typically have features like smaller seats, larger fuel tanks, and street-legal lighting and tires to make them suitable for both on-road and off-road adventures.
