Chain final-drive systems are the most common. In this technique, a sprocket installed to the result shaft (i.electronic., the shaft in the transmitting) is connected to a sprocket mounted on the rear wheel of the motorcycle by a steel chain. When the transmitting turns the smaller sized front sprocket, power can be transmitted along the chain to the larger rear sprocket, which in turn turns the rear wheel. This type of transmission system in automobile should be lubricated and adjusted, and the chain stretches and the sprockets use, requiring periodic replacements.

Belt drives
Belt drives are an alternative solution to chain drives. Early motorcycles often used leather belts, which could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Natural leather belts often slipped, especially in wet weather, therefore they were abandoned for additional materials and styles. By the 1980s, advancements in components made belt final-drive tranny system in automobile practical again. Today’s belts are constructed with cogged rubber and operate quite similar way as steel chains. Unlike metal chains, they don’t require lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are occasionally used. This transmission program in automobile transmits power to the back wheel via a drive shaft. Shaft drives are well-known because they are practical and don’t require as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes cause unwanted motion, known as shaft jacking, in the trunk of the motorcycle. The various other components that make a motorcycle a motorcycle are area of the chassis.
Advantages and Disadvantages
The major advantages of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes need their chains adjusting frequently and they could be expensive to replace when they wear out.
They need lubricating often, especially in bad weather, which can be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are completely enclosed and so are unaffected by the elements and only require periodic oil changes.

The disadvantages of shaft-drive are that it’s a lot heavier when compared to a chain and absorbs more of the engine’s power before it reaches the rear wheel

Compared to a Chain system

A shaft-drive can also change the action of the trunk suspension – when the throttle is opened and closed quickly the bike may rise and squat since the shaft is trying to “climb” the cog on the back wheel.

Power Transmission

The chain drive system is made up of two sprockets, one on the gearbox and one on the trunk wheel, that are connected by a chain.
In a shaft-driven transmission system in automobile, a shaft connects a gear within the gearbox to some other gear inside a hub on the rear wheel.
When the engine is sparked, power is transferred along the chain or shaft to the rear wheel, and the bike movements forward. Either system is commonly referred to as “final drive,” since it is usually the last group of components employed to deliver power to the trunk wheel.

Some manufacturers, notably Harley Davidson, have used belt drives on some of their model line-ups. BMW, Kawasaki, and Suzuki have also experimented with the belt drive system.
