Chain final-drive systems are the most common. In this technique, a sprocket mounted to the result shaft (i.electronic., the shaft in the tranny) is linked to a sprocket mounted on the trunk wheel of the motorcycle by a metallic chain. When the transmission turns the smaller front sprocket, power is certainly 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 agricultural Chain 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. Leather belts often slipped, specifically in wet weather, so they were abandoned for other materials and designs. By the 1980s, advancements in components made belt final-drive transmission system in automobile viable again. Today’s belts are constructed with 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 practical and don’t need as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes may cause unwanted motion, called shaft jacking, in the trunk 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 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 rear 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 trunk wheel.
Power Transmission
The chain drive system comprises of two sprockets, one on the 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 in the gearbox to some other gear inside a 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 some of their model line-ups. BMW, Kawasaki, and Suzuki also have attempted the belt drive system.
