Chain final-drive systems are the most common. In this system, a sprocket installed to the result shaft (i.e., the shaft in the transmitting) is connected 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 transmitted along the chain to the larger rear sprocket, which then turns the trunk wheel. This type of transmission program in automobile should be lubricated and altered, 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, that could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Leather belts often slipped, especially in wet weather, therefore these were abandoned for other materials and styles. By the 1980s, advances in components made belt final-drive transmitting system in automobile viable again. Today’s belts are made from 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 sometimes used. This transmission program in automobile transmits power to the rear wheel via a drive shaft. Shaft drives are popular because they are easy and don’t require as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes cause unwanted motion, known as shaft jacking, in the trunk of the motorcycle. The other components that make a motorcycle a motorcycle are portion of the chassis.
Advantages and Disadvantages
The major benefits of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes need their chains adjusting frequently plus they can be expensive to displace when 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 are unaffected by the weather and only need 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 can 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 rear wheel, that are connected by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear inside 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 movements forward. Either system is often referred to as “final drive,” since it is the last set of components employed to deliver power to the trunk wheel.

Some producers, 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.
