What is the maximum engine piston displacement for a motor-driven cycle?

The maximum engine piston displacement for a motor-driven cycle is indeed 250 cubic centimeters. This limit is significant because it differentiates motor-driven cycles from motorcycles, which typically have larger engine displacements. The definition of a motor-driven cycle as having a piston displacement of 250cc or less is crucial for regulatory purposes, affecting licensing requirements, safety regulations, and where these vehicles are permitted to operate.

Understanding this limit is important for anyone involved in law enforcement or traffic regulation, as it helps categorize vehicles appropriately and ensures compliance with local traffic laws. Vehicles exceeding this displacement are considered motorcycles and fall under different rules and regulations, which may include licensing for operators, registration, and insurance requirements. Therefore, knowing the proper classification based on engine displacement is vital for effective enforcement of traffic laws.
