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

Belt drives
Belt drives are an alternative to chain drives. Early motorcycles frequently used leather belts, which could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Leather-based belts often slipped, specifically in wet weather, so they were abandoned for additional materials and designs. By the 1980s, developments in materials made belt final-drive transmitting system in automobile practical again. Today’s belts are constructed with cogged rubber and operate much the same way as metal chains. Unlike steel 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 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 additional components that make a motorcycle a motorcycle are area of the chassis.
Advantages and Disadvantages
The major advantages of sprockets Shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes need their chains adjusting regularly and they could be expensive to replace when they wear out.
They need lubricating often, especially 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 elements and only require periodic oil changes.

The disadvantages of shaft-drive are that it is a lot heavier than 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 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 back wheel.

Power Transmission

The chain drive system comprises of two sprockets, one on the gearbox and one on the trunk wheel, that are linked by a chain.
In a shaft-driven transmission system in automobile, a shaft connects a gear in the gearbox to another gear in the 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 program is commonly known as “final drive,” since it is definitely the last group 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 experimented with the belt drive program.
