A "V-Twin" is a type of internal combustion engine that features two cylinders arranged in a V configuration. 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 Indian Motorcycle. The V-Twin engine operates by having the two cylinders fire alternately, which creates a distinctive sound and feel. This configuration is known for its strong low-end torque, making it ideal for cruising and providing a smooth ride. V-Twin engines are popular among motorcycle enthusiasts for their performance and unique character.
