Chain final-drive systems are the most common. In this system, a sprocket installed to the result shaft (i.e., the shaft in the transmitting) is linked to a sprocket attached to the rear wheel of the motorcycle by a steel chain. When the transmission turns the smaller front side sprocket, power can be transmitted along the chain to the larger rear sprocket, which then turns the trunk wheel. This type of transmission system in automobile must be lubricated and modified, and the chain chain sprocket stretches and the sprockets use, requiring periodic replacements.
Belt drives
Belt drives are an alternative to chain drives. Early motorcycles frequently used leather belts, which could be tensioned to provide traction using a spring-loaded pulley and hand lever. Natural leather belts often slipped, especially in wet weather, so they were abandoned for additional materials and designs. By the 1980s, advancements in components made belt final-drive transmission system in automobile viable again. Today’s belts are made from cogged rubber and operate much the same way as steel chains. Unlike metallic chains, they don’t need lubrication or cleaning solvents.
Shaft final-drive
Shaft final-drives are sometimes used. This transmission system in automobile transmits capacity to the back wheel with a drive shaft. Shaft drives are popular because they are convenient 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 rear of the motorcycle. The other components that make a motorcycle a motorcycle are portion 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 regularly and they can be costly to replace when they wear out.
They want lubricating often, specifically in bad weather, which can be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are fully enclosed and are unaffected by the weather and only need periodic oil changes.
The disadvantages of shaft-drive are that it's a lot heavier than a chain and absorbs more of the engine’s power before it reaches the rear wheel
In comparison to a Chain system
A shaft-drive may also change the action of the trunk suspension - when the throttle is opened and closed quickly the bike may rise and squat because the shaft is wanting to “climb” the cog on the back wheel.
Power Transmission
The chain drive system comprises of two sprockets, one on the gearbox and one on the rear wheel, that are connected by a chain.
In a shaft-driven transmission 
system in automobile, a shaft connects a gear inside the gearbox to another gear inside a hub on the rear wheel.
When the engine is sparked, power is transferred along the chain or shaft to the trunk wheel, and the bike techniques forward. Either system is often referred to as “final drive,” since it is certainly the last set of components employed to deliver power to the trunk wheel.
Some producers, notably Harley Davidson, have used belt drives on some of their model line-ups. BMW, Kawasaki, and Suzuki have also attempted the belt drive program.
