Chain final-drive systems are the most common. In this technique, a sprocket installed to the output shaft (i.electronic., the shaft in the transmitting) is linked 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 larger rear sprocket, which then turns the trunk wheel. This type of transmission program in automobile must be lubricated and modified, and the chain stretches and the sprockets use, requiring periodic replacements.
Belt drives
Belt drives are an alternative solution to chain drives. Early motorcycles often used leather belts, which could be tensioned to give traction using a spring-loaded pulley and hand lever. Leather-based belts often slipped, specifically in wet weather, so they were abandoned for other materials and designs. By the 1980s, advances in materials made belt final-drive transmitting system in automobile practical 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 sometimes used. This transmission system in automobile transmits capacity to the back wheel with a drive shaft. Shaft drives are popular because they are convenient and don’t require as much maintenance as chain-based systems. Drive Chain Nevertheless, shaft drives are heavier and sometimes cause unwanted motion, called shaft jacking, in the rear of the motorcycle. The additional components that make a motorcycle a motorcycle are section of the chassis.
Advantages and Disadvantages
The major advantages of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes require their chains adjusting regularly and they could be costly to replace when they wear out.
They want 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 weather and only need periodic oil changes.
The disadvantages of shaft-drive are that it’s 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 may also change the actions of the trunk suspension – when the throttle is opened and closed quickly the bike may 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 system in automobile, a shaft connects a gear in the gearbox to some other 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 program is commonly known as “final drive,” as it is usually the last set of components employed to deliver power to the rear wheel.
Some manufacturers, notably Harley Davidson, have used belt drives on a few of their model line-ups. BMW, Kawasaki, and Suzuki also have experimented with the belt drive system.
