Chain final-drive systems are the most common. In this system, a sprocket installed to the output shaft (i.electronic., the shaft in the transmitting) is linked to a sprocket mounted on the rear wheel of the motorcycle by a metallic chain. When the transmitting turns the smaller sized front sprocket, power is certainly transmitted along the chain to the larger rear sprocket, which then turns the trunk wheel. This kind of transmission program in automobile should be lubricated and adjusted, and the chain stretches and the sprockets wear, requiring periodic replacements.

Belt drives
Belt drives are an alternative solution to chain drives. Early motorcycles frequently used leather belts, which could be tensioned to give traction using a spring-loaded pulley and hand lever. Leather-based belts often slipped, especially in wet weather, so these were abandoned for various other materials and designs. By the 1980s, improvements in components made belt final-drive tranny system in automobile practical again. Today’s belts are constructed with agricultural Chain cogged rubber and operate much the same way as steel chains. Unlike steel chains, they don’t need lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are sometimes used. This transmission program in automobile transmits capacity to the rear wheel with a drive shaft. Shaft drives are well-known because they are easy and don’t need 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 other components that produce a motorcycle a motorcycle are part 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 frequently and they could be costly to replace if they wear out.
They need lubricating often, specifically in bad weather, which may be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are completely 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 trunk wheel

Compared to a Chain system

A shaft-drive can also change the action 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 system in automobile, a shaft connects a gear in the gearbox to some other gear in the 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 techniques forward. Either system is commonly referred to as “final drive,” as it can be the last set of components employed to provide 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 have also attempted the belt drive system.
