Chain final-drive systems are the most common. In this system, a sprocket mounted to the result shaft (i.e., the shaft in the transmission) is linked to a sprocket mounted on the rear wheel of the motorcycle by a metallic chain. When the transmission turns the smaller front sprocket, power can be transmitted along the chain to the bigger rear sprocket, which then turns the trunk wheel. This type of transmission program in automobile must be lubricated and modified, and the chain stretches and the sprockets use, requiring periodic replacements.

Belt drives
Belt drives are an alternative to chain drives. Early motorcycles often used leather belts, which could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Leather belts often slipped, specifically in wet weather, therefore they were abandoned for various other materials and designs. By the 1980s, improvements in components made belt final-drive transmitting system in automobile practical again. Today’s belts are made from cogged rubber and operate much the same way as steel chains. Unlike metal chains, they don’t need lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are occasionally used. This transmission system in automobile transmits power to the rear wheel with a drive shaft. Shaft drives are well-known because they are easy and don’t need 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 section of the chassis.
Advantages and Disadvantages
The major advantages of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes require their chains adjusting frequently and they could be expensive to replace if they wear out.
They need lubricating often, specifically in bad weather, which may be messy and inconvenient. And chain lube increases 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 is a lot heavier when compared to a chain and absorbs more of the engine’s power before it reaches the trunk wheel

Compared to a Chain system

A shaft-drive can also change the actions of the rear suspension – when the throttle is opened and closed quickly the bike can rise and squat since the shaft is trying 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 rear wheel, that are linked by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear in the gearbox to some other 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 system is commonly known as “final drive,” as it is definitely the last group of components employed to provide power to the rear wheel.

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