What Engine Displacement is Suitable for Highway Riding?

[DiVictoria]

Motorcycles with an engine displacement of 50cc or more are allowed on highways. Below is an introduction to motorcycles: 1. Basic Components: A motorcycle consists of five main parts: the engine, transmission system, running gear, steering and braking systems, and electrical instrumentation. 2. Working Principle: The four-stroke engine is widely used. In a four-stroke engine, the piston completes four strokes (intake, compression, power, and exhaust) for each ignition cycle. During the intake stroke, the intake valve opens, the piston moves downward, and a mixture of gasoline and air is drawn into the cylinder. Then, both the intake and exhaust valves close, and the piston moves upward, compressing the mixture. When the mixture is compressed to its minimum volume, the spark plug ignites it, and the resulting combustion pressure drives the piston downward, rotating the crankshaft. At the end of the power stroke, the exhaust valve opens, allowing the piston to push out the exhaust gases as it moves upward again. 3. Engine Displacement Calculation: Engine displacement (in cc) is calculated as: Cross-sectional area of the cylinder × Stroke length × Number of cylinders = Total displacement (cc).
