High tension motors

Chain final-drive systems are the most common. In this system, a sprocket installed to the result shaft (i.e., the shaft in the transmitting) is linked to a sprocket mounted on the trunk wheel of the motorcycle by a metal chain. When the transmission turns the smaller sized front sprocket, power is transmitted along the chain to the larger rear sprocket, which in turn turns the rear wheel. This kind of transmission system in automobile must be lubricated and altered, 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 often used leather belts, that could be tensioned to provide traction using a spring-loaded pulley and hand lever. Leather-based 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 transmission system in automobile viable again. Today’s belts are made from cogged rubber and operate quite similar way as metal chains. Unlike metallic chains, they don’t need lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are sometimes used. This transmission system in automobile transmits power to the back wheel with a drive shaft. Shaft drives are well-known because they are practical and don’t need as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes cause unwanted motion, known as shaft jacking, in the rear of the motorcycle. The additional components that make a motorcycle a motorcycle are area 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 frequently and they can be expensive to replace when they wear out.
They need lubricating often, specifically in bad weather, which may be messy and inconvenient. And chain lube adds to the running costs.
Shaft-drive systems are completely enclosed and so 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 may also change the action of the rear suspension – when the throttle is opened and closed quickly the bike may rise and squat because 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 linked by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear in the gearbox to another gear inside a 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 Conveyor Chain commonly known as “final drive,” as it can be the last group of components employed to deliver power to the rear wheel.

Some manufacturers, 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 system.
