How do motorcycle engines work?

Motorcycle engines operate on the principle of internal combustion, where fuel and air mix and ignite within the engine's cylinders. This combustion creates high-pressure gases that push down on the pistons, converting chemical energy into mechanical energy. The pistons are connected to a crankshaft, which converts their linear motion into rotational motion, ultimately powering the motorcycle's wheels. Most motorcycles use either a two-stroke or four-stroke cycle, with the latter being more common in modern designs due to its efficiency and lower emissions.
