Chain final-drive systems are by far the most common. In this technique, a sprocket installed to the output shaft (i.electronic., the shaft in the transmission) is linked to a sprocket mounted on the rear wheel of the motorcycle by a steel chain. When the transmission turns the smaller front sprocket, power is definitely transmitted along the chain to the larger rear sprocket, which in turn turns the rear wheel. This kind of transmission program in automobile must be lubricated and altered, and the chain stretches and the sprockets wear, requiring periodic replacements.

Belt drives
Belt drives are an alternative to chain drives. Early motorcycles frequently used leather belts, which could be tensioned to provide traction using a spring-loaded pulley and hand lever. Leather belts often slipped, specifically in wet weather, therefore they were abandoned for additional materials and styles. By the 1980s, developments in components made belt final-drive transmission system in automobile viable again. Today’s belts are made from cogged rubber and operate quite similar 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 rear wheel via a drive shaft. Shaft drives are well-known because they are hassle-free 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 rear of the motorcycle. The additional components that produce 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. Drive Chain Chain-drive bikes require their chains adjusting frequently and they can 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 so 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 rear wheel

Compared to a Chain system

A shaft-drive can also change the actions 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 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 program in automobile, a shaft connects a gear in 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 movements forward. Either program is commonly referred to as “final drive,” since it is the last set of components employed to provide 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 attempted the belt drive system.
