Chain final-drive systems are by far the most Leaf Chain common. In this technique, a sprocket installed to the output shaft (i.e., the shaft in the transmitting) is linked to a sprocket attached to the rear wheel of the motorcycle by a metal chain. When the transmitting turns the smaller sized front sprocket, power can be transmitted along the chain to the bigger rear sprocket, which in turn turns the trunk wheel. This kind of transmission program in automobile must be lubricated and modified, and the chain stretches and the sprockets put on, requiring periodic replacements.

Belt drives
Belt drives are an alternative solution to chain drives. Early motorcycles frequently used leather belts, that could be tensioned to provide traction using a spring-loaded pulley and hand lever. Natural leather belts often slipped, especially in wet weather, so these were abandoned for additional materials and designs. By the 1980s, developments in components made belt final-drive transmitting system in automobile viable once again. Today’s belts are constructed with 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 via a drive shaft. Shaft drives are well-known because they are convenient and don’t need as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes may cause unwanted motion, called shaft jacking, in the trunk of the motorcycle. The additional components that make a motorcycle a motorcycle are section 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 frequently and they could be costly to replace when 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 are unaffected by the weather and only need 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 trunk wheel

Compared to a Chain system

A shaft-drive can also change the action 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 trunk wheel, that are linked by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear inside 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 trunk 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 deliver power to the rear wheel.

Some manufacturers, notably Harley Davidson, have used belt drives on a few of their model line-ups. BMW, Kawasaki, and Suzuki have also attempted the belt drive program.
