Chain final-drive systems are by far the most common. In this system, a sprocket mounted to the result shaft (i.electronic., the shaft in the transmitting) is linked to a sprocket mounted on the rear wheel of the motorcycle by a metallic chain. When the transmitting turns the smaller front sprocket, power is definitely transmitted along the chain to the larger rear sprocket, which in turn turns the trunk wheel. This kind of transmission program in automobile must be lubricated and modified, and the chain stretches and the sprockets put on, requiring periodic replacements.
Belt drives
Belt drives are an alternative to chain drives. Early motorcycles frequently used leather belts, that could be tensioned to give traction utilizing a spring-loaded pulley and hand lever. Natural leather belts often slipped, especially in wet weather, so these were abandoned for various other materials and designs. By the 1980s, improvements in components made belt final-drive transmission system in automobile viable once 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 program in automobile transmits capacity to the rear wheel with a drive shaft. Shaft drives are popular 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, called shaft jacking, in the trunk of the motorcycle. The other components that make a motorcycle a motorcycle are part of the chassis.
Advantages and Disadvantages
The major benefits of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes require their chains adjusting frequently and they can be expensive to replace if they wear out.
They need lubricating often, especially in bad weather, which may be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are fully enclosed and so are unaffected by the elements and only require 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 trunk wheel
In comparison to a Chain system
A shaft-drive can also change the actions of the trunk suspension – when the throttle is opened and closed quickly the bike can rise and squat since the shaft is wanting to “climb” the cog on the trunk 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 inside 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 trunk wheel, and the bike moves forward. Either system is commonly known as “final drive,” since it can be the last group of components employed to deliver power to the rear wheel.
Some producers, notably Harley Davidson, have used belt drives on a few of their model line-ups. BMW, Kawasaki, and Suzuki also have experimented with the belt drive program.
