The first dirt bikes were predominantly based on two-stroke engines, as these engines were lighter and provided better power-to-weight ratios, making them ideal for off-road conditions. However, the classification of the very first dirt bike can vary, as the evolution of off-road motorcycles involved various engine types. The popularization of two-stroke dirt bikes began in the mid-20th century, particularly with models like the BSA Bantam and others that followed. Overall, while many early dirt bikes were two-stroke, not all of them were exclusively so.
