Chain final-drive systems are the most common. In this technique, a sprocket mounted to the output shaft (i.e., the shaft in the transmitting) is linked to a sprocket attached to the rear wheel of the motorcycle by a metal chain. When the transmission turns the smaller sized front sprocket, power can be transmitted along the chain to the larger rear sprocket, which then turns the trunk wheel. This kind 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 often used leather belts, that could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Natural leather belts often slipped, especially in wet weather, therefore they were abandoned for various other materials and styles. By the 1980s, advances in materials made belt final-drive transmitting system in automobile viable again. Today’s belts are constructed with cogged rubber and operate much the same way as metallic chains. Unlike metal chains, they don’t require lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are occasionally used. This transmission program in automobile transmits power to the rear wheel with a drive shaft. Shaft drives are popular because they are easy 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 rear of the motorcycle. The other components that produce a motorcycle a motorcycle are section 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 regularly and they could be costly to replace if they wear out.
They want lubricating often, specifically in bad weather, which can 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 rear wheel

Compared to a Chain system

A shaft-drive may also change the actions of the trunk suspension – when the throttle is opened and closed quickly the bike can rise and squat because the shaft is trying to “climb” the cog on the back 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 system in automobile, a shaft connects a gear in the gearbox to some other gear in the hub on the rear wheel.
When the engine is sparked, power is transferred along the chain or shaft to the rear wheel, and the bike techniques forward. Either system is commonly referred to as “final drive,” since it is certainly 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 have also attempted the belt drive program.
