Chain final-drive Auto Chain systems are the most common. In this technique, a sprocket mounted to the result shaft (i.electronic., the shaft in the tranny) is linked to a sprocket attached to the trunk wheel of the motorcycle by a metal chain. When the transmission turns the smaller front sprocket, power is definitely transmitted along the chain to the larger rear sprocket, which in turn turns the trunk wheel. This kind of transmission program in automobile should be lubricated and adjusted, 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, that could be tensioned to give traction using a spring-loaded pulley and hand lever. Leather belts often slipped, specifically in wet weather, therefore these were abandoned for various other materials and designs. By the 1980s, improvements in materials made belt final-drive tranny system in automobile practical once again. Today’s belts are made from cogged rubber and operate quite similar way as metallic chains. Unlike metal 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 rear wheel with a drive shaft. Shaft drives are well-known because they are hassle-free and don’t need as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes cause unwanted motion, known as 
shaft jacking, in the trunk of the motorcycle. The additional components that produce a motorcycle a motorcycle are area 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 frequently and they could be costly to replace when they wear out.
They need lubricating often, specifically 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 need periodic oil changes.
The disadvantages of shaft-drive are that it is a lot heavier when compared to a chain and absorbs more of the engine’s power before it reaches the trunk 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 since the shaft is trying to “climb” the cog on the back wheel.
Power Transmission
The chain drive system is made up of two sprockets, one on the gearbox and one on the rear wheel, that are connected by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear inside the gearbox to another 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 movements forward. Either system is commonly referred to as “final drive,” as it is definitely the last set of components employed to deliver 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 also have attempted the belt drive program.
