Chain final-drive systems are by far the most common. In this technique, a sprocket mounted to the output shaft (i.electronic., the shaft in the tranny) is linked to a sprocket mounted on the trunk wheel of the motorcycle by a steel chain. When the tranny turns the smaller front sprocket, power is definitely transmitted along the chain 
to the larger rear sprocket, which then turns the rear wheel. This kind of transmission program in automobile should be lubricated and modified, and the chain stretches and the sprockets wear, requiring periodic replacements.
Belt drives
Belt drives are an alternative to chain drives. Early motorcycles often used leather belts, that could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Natural leather belts often slipped, specifically in wet weather, therefore these were abandoned for other materials and styles. By the 1980s, developments in components made belt final-drive transmission system in automobile practical again. Today’s belts are made of cogged rubber and operate quite similar way as metallic chains. Unlike steel chains, they don’t require lubrication or cleaning solvents.
Shaft final-drive
Shaft final-drives are occasionally used. This transmission system in automobile transmits capacity to the back wheel with a drive shaft. Shaft drives are well-known because they are practical and don’t require as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes cause unwanted motion, called shaft jacking, in the rear of the motorcycle. The other components that produce a motorcycle a motorcycle are portion of the chassis.
Advantages and Disadvantages
The major benefits of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes need their chains adjusting regularly and they could be costly to replace when they wear out.
They need 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 elements and only need periodic oil changes.
The disadvantages of shaft-drive are that it is a lot heavier when compared to 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 actions of the rear suspension – when the throttle is opened and closed quickly the bike may rise and squat since the shaft is wanting to “climb” the cog on the back wheel.
Power Transmission
The chain drive system is made up of two sprockets, one on the Leaf Chain gearbox and one on the trunk wheel, that are connected by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear within the gearbox to another gear in the hub on the trunk wheel.
When the engine is sparked, power is transferred along the chain or shaft to the rear wheel, and the bike movements forward. Either program is commonly known as “final drive,” as it is certainly the last set of components employed to provide power to the trunk wheel.
Some manufacturers, notably Harley Davidson, have used belt drives on a few of their model line-ups. BMW, Kawasaki, and Suzuki have also experimented with the belt drive system.
