A V-twin engine is a type of internal combustion engine that features two cylinders arranged in a V shape. This design allows for a compact engine size while providing a good balance of power and torque. V-twin engines are commonly found in motorcycles, particularly those made by brands like Harley-Davidson and Ducati, as well as in some ATVs and snowmobiles. The V-twin configuration can vary in terms of angle, typically ranging from 45 to 90 degrees. This angle affects the engine's performance and sound, contributing to the distinctive rumble associated with V-twin motorcycles. The design also allows for smoother operation and can enhance the overall riding experience.
