Chain final-drive systems are by far the most common. In this technique, a sprocket installed to the result shaft (i.electronic., the shaft in the tranny) is linked to a sprocket mounted on the rear wheel of the motorcycle by a steel chain. When the transmission turns the smaller front sprocket, power is transmitted along the chain to the larger rear sprocket, which in turn turns the trunk wheel. This type of transmission system in automobile must be lubricated and altered, and the chain stretches and the sprockets put on, requiring periodic replacements.
Belt drives
Belt drives are an alternative to chain drives. Early motorcycles often used leather belts, that could be tensioned to give traction using a spring-loaded pulley and hand lever. Leather-based belts often slipped, especially in wet weather, therefore these were abandoned for various other materials and styles. By the 1980s, developments in components made belt final-drive tranny system in automobile practical again. Today’s belts are constructed with cogged rubber and operate quite similar way as steel chains. Unlike steel chains, they don’t need lubrication or cleaning solvents.
Shaft final-drive
Shaft final-drives are occasionally used. This transmission system in automobile transmits capacity to the rear wheel via a drive shaft. Shaft drives are popular because they are practical and don’t require as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes may cause unwanted motion, called shaft jacking, in the rear of the motorcycle. The various other components that produce a motorcycle a motorcycle are area of the chassis.
Advantages and Disadvantages
The major benefits of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes require their chains adjusting regularly plus they can be costly to displace when they degrade.
They want lubricating often, specifically in bad weather, which can be messy and inconvenient. And chain lube increases the running costs.
Shaft-drive systems are completely enclosed and so are unaffected by the weather and only need periodic oil changes.
The disadvantages of shaft-drive are that it’s 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 because 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 trunk wheel, that are connected by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear in the gearbox to another gear in the hub on the trunk wheel.
When the engine is sparked, power is transferred along the chain or shaft to the rear wheel, and the bike moves forward. Either system is commonly known as “final drive,” as it is usually the last group of components employed to provide power to the rear wheel.
Some producers, notably Harley Davidson, have used belt drives on some of their model line-ups. BMW, Kawasaki, and Suzuki also have experimented with the belt drive system.
