Ergal Racing Motorcycle Sprockets

Racing motorcycle aluminium rear sprockets are essential final-drive components designed to improve response, gearing and motorcycle configuration. In this section, you will find aluminium motorcycle rear sprockets designed for road, sport and racing use.

Replacing the original rear sprocket allows the motorcycle’s behaviour to be modified by changing the final-drive ratio, providing quicker acceleration response or a setup better suited to the rider’s style.

The rear sprocket works together with the chain, front sprocket, wheel hub, chain adjusters and other transmission components. For a complete configuration, you can also visit the motorcycle transmission category.

Racing motorcycle aluminium rear sprockets

Racing motorcycle aluminium rear sprockets are designed to provide low weight, durability and precise power transmission to the rear wheel. They are highly valued by riders seeking to improve the motorcycle’s technical configuration with a targeted upgrade.

Thanks to their aluminium alloy construction and specific tooth profile, these rear sprockets allow the motorcycle’s response to be adapted to different uses, from road riding to track use.

Aluminium motorcycle rear sprockets

An aluminium motorcycle rear sprocket is ideal for riders seeking a lightweight, sport-oriented component suitable for racing configurations. Choosing the correct number of teeth is important because it directly affects acceleration, drive and final-drive behaviour.

• Allows the motorcycle’s final-drive ratio to be changed
• Can provide quicker acceleration response
• Reduces weight compared with some original rear sprockets
• Works with compatible front sprockets, chains, wheel hubs and chain adjusters
• Ideal for road, sport and racing motorcycles
• Allows a more technical and customised configuration

Benefits of racing motorcycle rear sprockets

• Technical upgrade for the final drive
• Greater customisation of the gear ratio
• Response better suited to the rider’s style
• More racing-inspired styling around the rear wheel
• Perfect match with compatible front sprockets and chains
• Ideal solution for road, sport and track use
• More precise, lightweight and professional configuration

Gear ratio, acceleration and sport riding

Changing the motorcycle rear sprocket allows the final-drive ratio to be modified, influencing the motorcycle’s behaviour. A different number of teeth can provide quicker acceleration or longer gearing, depending on the selected configuration.

When combined with the front sprocket, chain, wheel hub and adjustable chain tensioner, an aluminium rear sprocket provides a more refined transmission setup suitable for sport use.

Motorcycle rear sprockets for road and track use

On the road, a racing rear sprocket can improve motorcycle response and make riding more dynamic. On the track or during sport riding, it becomes even more important because the gearing can be adapted to the circuit and the rider’s style.

Before purchasing, always check the motorcycle make, model and year, chain pitch, number of teeth, compatibility with the wheel hub and front sprocket, and the information provided on the product page.
