Chain final-drive systems are by far the most common. In this system, a sprocket installed to the output shaft (i.electronic., the shaft in the transmission) is connected to a sprocket attached to the rear wheel of the motorcycle by a steel chain. When the transmission turns the smaller sized front sprocket, power is definitely transmitted along the chain to the larger rear sprocket, which then turns the trunk wheel. This type of transmission system in automobile should 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 utilizing a Drive Chain spring-loaded pulley and hand lever. Leather belts often slipped, especially in wet weather, so they were abandoned for other materials and designs. By the 1980s, advancements in materials made belt final-drive tranny system in automobile viable once again. Today’s belts are made from cogged rubber and operate quite similar way as metallic chains. Unlike steel 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 convenient 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 make a motorcycle a motorcycle are part of the chassis.
Advantages and Disadvantages
The major advantages of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes need their chains adjusting frequently and they could be costly to replace if they wear out.
They need lubricating often, especially in bad weather, which can 
be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are fully 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 when compared to a chain and absorbs more of the engine’s power before it reaches the rear wheel
Compared 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 may rise and squat since the shaft is wanting 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 connected by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear within the gearbox to another 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 movements forward. Either system is commonly referred to as “final drive,” as it is definitely 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 also have experimented with the belt drive program.
