What is the reason why a motorcycle does not move when in gear?

It may be due to a damaged automatic centrifugal clutch. Motorcycle: A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine and steered by handlebars. It is lightweight, flexible, and fast, widely used for patrol, passenger and cargo transportation, and also serves as sports equipment. Broadly speaking, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. Power knowledge: Horsepower was initially defined by the French and Germans. However, since the horses used to measure horsepower were smaller than average, an engine with 50 horsepower should not be imagined as being pulled by 50 horses, but rather by 35 horses, which is more appropriate. The unit of horsepower is represented by (ps), a symbol first used by the Germans and still in use today.
