Chain final-drive systems are by far the most common. In this technique, a sprocket mounted 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 metal chain. When the transmitting turns the smaller front side sprocket, power can be transmitted along the chain to the bigger rear sprocket, which in turn turns the rear wheel. This type of transmission system in automobile must be lubricated and modified, 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, that could be tensioned to provide traction using a spring-loaded pulley and hand lever. Leather-based belts often slipped, especially in wet weather, therefore these were abandoned for additional materials and styles. By the 1980s, developments in components made belt final-drive transmitting system in automobile viable once again. Today’s belts are constructed with cogged rubber and operate quite similar way as metal chains. sprockets Unlike steel 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 back wheel via a drive shaft. Shaft drives are well-known because they are convenient and don’t need as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes may cause unwanted motion, known as shaft jacking, in the trunk of the motorcycle. The additional components that produce a motorcycle a motorcycle are part 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 regularly plus they can be costly to replace when 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 fully enclosed and so are unaffected by the weather 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 rear suspension – when the throttle is opened and closed quickly the bike may rise and squat since 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 linked by a chain.
In a shaft-driven transmission system in automobile, a shaft connects a gear inside the gearbox to some other gear inside a 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 moves forward. Either system is often referred to as “final drive,” as 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 also have attempted the belt drive system.
