Why should passengers keep their feet on the footrests even when the motorcycle is stopped?

Keeping feet on the footrests while the motorcycle is stopped primarily serves to avoid contact with moving parts and heat sources. Motorcycles have various components that can become extremely hot during operation, such as the exhaust system, and they may also have moving parts that can pose a danger if a passenger inadvertently touches them. By keeping their feet on the footrests, passengers can ensure they remain safely positioned and reduce the risk of burns or injury from the motorcycle's mechanical components.

Other options may refer to aspects of riding safety, balance, or comfort, but they do not address the critical safety concern associated with foot placement when the motorcycle is stopped. Maintaining proper passenger posture, aiding the motorcyclist in balance, or preventing engine overheating, while important in various contexts of motorcycle operation, do not emphasize the immediate risk of injury from nearby components that passengers might encounter if their feet are not positioned correctly.
