Chain final-drive systems are by far the most common. In this technique, a sprocket installed to the result shaft (i.e., the shaft in the transmitting) is connected 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 certainly transmitted along the chain to the larger rear sprocket, which then turns the rear wheel. This type of transmission program in automobile should be lubricated and modified, 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 provide traction using a spring-loaded pulley and hand lever. Leather belts often slipped, especially in wet weather, so these were abandoned for other materials and styles. By the 1980s, developments in materials made belt final-drive tranny system in automobile practical once again. Today’s belts are made of cogged rubber and operate quite similar way as metal chains. Unlike steel chains, they don’t require lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are occasionally used. This transmission program in automobile transmits power to the rear wheel with a drive shaft. Shaft drives are Drive Chain popular because they are convenient and don’t need as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes cause unwanted motion, called shaft jacking, in the rear of the motorcycle. The various other components that produce 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 expensive 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 completely enclosed and are unaffected by the weather and only require 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 may also change the action of the rear 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 back 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 system 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 moves forward. Either system is commonly known as “final drive,” as it is the last group of components employed to deliver power to the trunk wheel.

Some manufacturers, 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 system.
