motorcycle chains and sprockets

Chain final-drive systems are by far the most common. In this system, a sprocket mounted to the output shaft (i.electronic., the shaft in the transmission) is linked to a sprocket mounted on the trunk wheel of the motorcycle by a metal chain. When the transmission turns the smaller front sprocket, power can be transmitted along the chain to the bigger rear sprocket, which in turn turns the rear wheel. This type of transmission program in automobile should be lubricated and adjusted, and the chain stretches and the sprockets use, 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 utilizing a spring-loaded pulley and hand lever. Leather-based belts often slipped, specifically in wet weather, therefore they were abandoned for other materials and designs. By the 1980s, developments in materials made belt final-drive transmission system in automobile viable once again. Today’s belts are made from cogged rubber and operate much the same way as steel 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 back wheel via a drive shaft. Shaft drives are popular 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, called shaft jacking, in the rear of the motorcycle. The additional 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 can be expensive to replace if they wear out.
They need lubricating often, specifically in bad weather, which can be messy and inconvenient. And chain lube increases 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’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 may also change the action of the trunk suspension – when the throttle is opened and closed quickly the bike can rise and squat because the shaft is trying 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 trunk wheel, that are connected by a chain.
In a shaft-driven transmission system in automobile, a shaft connects a gear inside the gearbox to another gear in the hub on the trunk wheel.
When the engine is sparked, power is transferred along the chain or shaft to the trunk wheel, and the bike movements forward. Either program is commonly known as “final drive,” as it can be the last set of components employed to deliver power to the rear 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 system.
