Chain final-drive systems are the most common. In this system, a sprocket mounted to the result shaft (i.electronic., the shaft in the tranny) is linked to a sprocket mounted on the rear wheel of the motorcycle by a steel chain. When the tranny turns the smaller sized front sprocket, power is usually transmitted along the chain to the 
bigger rear sprocket, which then turns the rear wheel. This type of transmission program in automobile must be lubricated and altered, and the chain stretches and the sprockets put on, requiring periodic replacements.
Belt drives
Belt drives are an alternative solution to chain drives. Early motorcycles frequently used leather belts, that could be tensioned to provide traction using a spring-loaded pulley and hand lever. Leather-based belts often slipped, specifically in wet weather, therefore these were abandoned for additional materials and designs. By the 1980s, developments in components made belt final-drive tranny system in automobile practical once again. Today’s belts are made of cogged rubber and operate quite similar way as metallic chains. Unlike metallic chains, they don’t require lubrication or cleaning solvents.
Shaft final-drive
Shaft final-drives are sometimes used. This transmission program in automobile transmits power to the rear wheel via a drive shaft. Shaft drives are well-known because they are hassle-free and don’t require as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes cause chain sprocket unwanted motion, called shaft jacking, in the rear of the motorcycle. The various 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 require their chains adjusting regularly and they could be costly to replace when they wear out.
They want 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 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 rear 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 may rise and squat because 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 rear wheel, that are linked by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear inside the gearbox to another gear inside a hub on the trunk 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 is usually the last group of components employed to deliver power to the trunk wheel.
Some producers, 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 program.
