Chain final-drive systems are the most common. In this technique, a sprocket mounted to the result shaft (i.e., the shaft in the tranny) is Leaf Chain linked to a sprocket attached to the trunk wheel of the motorcycle by a steel chain. When the transmission 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 type 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 to chain drives. Early motorcycles often used leather belts, which could be tensioned to give traction using a spring-loaded pulley and hand lever. Natural leather belts often slipped, especially in wet weather, therefore they were abandoned for various other materials and designs. By the 1980s, 
developments in materials made belt final-drive transmission system in automobile viable again. Today’s belts are made of 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 program in automobile transmits capacity to the back wheel via a drive shaft. Shaft drives are popular because they are convenient and don’t require as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes may cause unwanted motion, known as shaft jacking, in the rear of the motorcycle. The other components that make 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 require their chains adjusting frequently and they can be expensive to replace if they wear out.
They want lubricating often, especially in bad weather, which can 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’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 can also change the actions of the rear 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 rear wheel, that are linked by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear within 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 rear wheel, and the bike techniques forward. Either system is commonly known as “final drive,” since it is usually the last set 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 attempted the belt drive system.
