Chain final-drive systems are by far the most common. In this system, a sprocket installed to the result shaft (i.e., the shaft in the transmitting) is linked to a sprocket attached to the rear wheel of the motorcycle by a metallic chain. When the transmitting turns the smaller front side sprocket, power is usually transmitted along the chain to the bigger rear sprocket, which then turns the rear wheel. This kind of transmission program in automobile should be lubricated and modified, and the chain stretches and the sprockets sprockets put on, requiring periodic replacements.

Belt drives
Belt drives are an alternative 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 belts often slipped, especially in wet weather, therefore they were abandoned for other materials and designs. By the 1980s, improvements in components made belt final-drive transmitting system in automobile viable again. Today’s belts are made from cogged rubber and operate quite similar way as steel chains. Unlike metal chains, they don’t require lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are occasionally used. This transmission system in automobile transmits power to the back wheel via a drive shaft. Shaft drives are well-known because they are convenient and don’t require as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes cause unwanted motion, known as shaft jacking, in the trunk of the motorcycle. The various other components that produce 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 need their chains adjusting regularly and they can be expensive to displace when they degrade.
They want lubricating often, especially in bad weather, which can be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are fully enclosed and so 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 may also change the action of the rear suspension – when the throttle is opened and closed quickly the bike may rise and squat because the shaft is wanting to “climb” the cog on the back 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 inside the gearbox to another gear inside a hub on the rear 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 referred to as “final drive,” as it can be the last set of components employed to deliver 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 have also experimented with the belt drive program.
