High tension motors

Chain final-drive systems are the most common. In this system, a sprocket installed to the output shaft (i.e., the shaft in the tranny) is linked to a sprocket mounted on the rear wheel of the motorcycle by a metal chain. When the transmission turns the smaller front sprocket, power is transmitted along the chain to the bigger rear sprocket, which in turn turns the trunk wheel. This type of transmission program in automobile should be lubricated and adjusted, 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 give traction utilizing a spring-loaded pulley and hand lever. Leather belts often slipped, especially in wet weather, so they were abandoned for other materials and designs. By the 1980s, improvements in components made belt final-drive transmission Auto Chain system in automobile viable once again. Today’s belts are made from cogged rubber and operate much the same way as metallic chains. Unlike steel chains, they don’t require lubrication or cleaning solvents.

Shaft final-drive
Shaft final-drives are occasionally used. This transmission system in automobile transmits capacity to the back wheel via a drive shaft. Shaft drives are popular because they are convenient and don’t require as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes cause unwanted motion, known as shaft jacking, in the rear of the motorcycle. The additional components that produce 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 regularly and they could be costly to replace if 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 elements and only require periodic oil changes.

The disadvantages of shaft-drive are that it’s a lot heavier than 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 action of the rear suspension – when the throttle is opened and closed quickly the bike can rise and squat because the shaft is wanting to “climb” the cog on the back wheel.

Power Transmission

The chain drive system is made up of two sprockets, one on the gearbox and one on the rear wheel, that are connected by a chain.
In a shaft-driven transmission system in automobile, a shaft connects a gear inside 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 trunk wheel, and the bike moves forward. Either system is commonly referred to as “final drive,” as it is usually the last group of components employed to provide 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 also have experimented with the belt drive program.
