Ergal Racing Motorcycle Sprockets

Ergal racing motorcycle rear sprockets are final-drive components used to configure gearing and transfer drive through the chain to the rear wheel. This section includes aluminium motorcycle rear sprockets for road, sport and racing applications.

Changing the original rear sprocket changes the final-drive ratio and therefore affects acceleration and engine speed at a given road speed.

The rear sprocket works together with the chain, front sprocket, wheel hub and chain tensioners. All components must use compatible specifications.

Ergal racing motorcycle rear sprockets

Ergal racing rear sprockets are designed to provide low mass and accurate engagement with a compatible chain. They are commonly selected for sport and racing final-drive configurations.

Tooth count and material should always be chosen according to the motorcycle, chain pitch and intended use.

Ergal motorcycle rear sprockets

An ergal motorcycle rear sprocket is a lightweight option for compatible racing and sport applications. Tooth count directly influences the final-drive ratio and therefore motorcycle response.

• Allows the final-drive ratio to be changed
• Can alter acceleration characteristics
• Can reduce weight compared with heavier sprocket designs
• Works with compatible front sprockets, chains, hubs and chain tensioners
• Available for road, sport and racing motorcycles
• Allows a more application-specific final-drive setup

Benefits of racing motorcycle rear sprockets

• Technical adjustment of the final drive
• Greater choice of final-drive ratios
• Gearing tailored to the intended use
• Racing-inspired rear-wheel appearance
• Works with compatible front sprockets and chains
• Useful for road, sport and track configurations
• Lightweight option depending on material and original component

Gearing, acceleration and sport riding

Changing the motorcycle rear sprocket changes the final-drive ratio. A different tooth count can favour stronger acceleration or lower engine speed at a given road speed depending on the complete gearing combination.

When paired with a compatible front sprocket, chain, wheel hub and chain tensioner, the rear sprocket forms part of a complete final-drive setup.

Motorcycle rear sprockets for road and track use

On the road, gearing can be selected according to the desired balance between acceleration and cruising. On the track, the ratio can be adapted to circuit layout and riding requirements.

Before purchasing, check the motorcycle make, model and year, chain pitch, tooth count, wheel-hub compatibility, front sprocket and all fitment information.

Frequently asked questions about ergal racing motorcycle rear sprockets

What does a motorcycle rear sprocket do?

It forms part of the final drive and works with the chain and front sprocket to transmit power to the rear wheel.

Does changing the rear sprocket change how the motorcycle rides?

Yes. Changing tooth count changes the final-drive ratio and therefore acceleration and engine speed for a given road speed.

Are ergal rear sprockets suitable for road use?

It depends on the product and application. Use only a sprocket specified for the motorcycle, chain pitch and intended use.

How do I choose the correct motorcycle rear sprocket?

Check the motorcycle make, model and year, chain pitch, tooth count, wheel-hub compatibility, front sprocket and the product fitment information.
