Chain final-drive systems are the most common. In this technique, a sprocket installed to the result shaft (i.electronic., the shaft in the transmission) is linked to a sprocket mounted on the rear wheel of the motorcycle by a metal chain. When the transmission turns the smaller sized front sprocket, power is certainly transmitted along the chain to the bigger rear sprocket, which then turns the rear wheel. This kind of transmission program in automobile must be lubricated and adjusted, 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 utilizing a spring-loaded pulley and hand lever. Natural leather belts often slipped, specifically in wet weather, therefore these were abandoned for additional materials and styles. By the 1980s, developments in materials made belt final-drive tranny system in automobile practical once again. Today’s belts are constructed with cogged rubber and operate quite similar way as metallic chains. Unlike metal chains, they don’t need lubrication or cleaning solvents.
Shaft final-drive
Shaft final-drives are sometimes used. This transmission system in automobile transmits capacity to the back wheel via a drive shaft. Shaft drives are well-known because they are easy and don’t need as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes may cause unwanted motion, known as shaft jacking, in the trunk of the motorcycle. The additional 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 need their chains adjusting regularly and they can be expensive to replace if they wear out.
They need lubricating often, specifically in bad weather, which may be messy and inconvenient. And chain lube increases the running costs.
Shaft-drive systems are fully enclosed and so are unaffected by the weather and only need 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 rear wheel
In comparison to a Chain system
A shaft-drive may also change the actions of the rear suspension – when the throttle is opened and closed quickly the bike can rise and squat since the shaft is wanting to “climb” the cog on the trunk 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 system in automobile, a shaft connects a gear within the gearbox to some other gear in the hub on the rear 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,” since it can be the last group 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 have also experimented with the belt drive program.
