In the Omnia Racing catalog you can purchase motorcycle sprockets available in different tooth counts, materials and finishes, suitable for OEM replacement, aesthetic upgrades and more sport-oriented setups. You can choose sprockets with different tooth configurations to maintain the original gearing or to make the motorcycle more responsive under acceleration or more relaxed at higher speeds, always checking compatibility with the motorcycle chain, front sprocket, transmission pitch and motorcycle model.

Among the most appreciated brands by riders you will find PBR, a benchmark for OEM replacement parts and compatible solutions for a huge number of motorcycle models, available in different materials such as steel sprockets and hard anodized ergal sprockets, with multiple tooth options to adapt the gearing ratio to different riding needs. For riders looking for a more premium and visually refined solution, CNC Racing and AEM offer lightweight ergal motorcycle sprockets with high-end finishes and aggressive styling, highly appreciated on sport bikes, naked motorcycles and high-level custom builds.

A rear sprocket with more teeth generally makes the motorcycle more responsive under acceleration, while a sprocket with fewer teeth can lengthen the final gearing. Every gearing modification should be evaluated carefully, because it may affect engine RPM, top speed, fuel consumption, chain tension and the overall riding behaviour of the motorcycle. For this reason, it is important to choose the sprocket together with other transmission components such as the front sprocket and motorcycle chain.

How do you choose the correct motorcycle sprocket?

To choose the correct motorcycle sprocket, it is necessary to verify the motorcycle model, chain pitch, tooth count, mounting pattern, material and compatibility with the chain and front sprocket. If you want to modify the gearing ratio, you should also evaluate the desired riding characteristics of the motorcycle.

What happens when increasing the number of teeth on a motorcycle sprocket?

Increasing the number of teeth on the rear sprocket generally makes the motorcycle more responsive in acceleration and throttle pickup, but it may reduce top speed and increase engine RPM at cruising speeds. It is a common modification for riders looking for quicker response and stronger acceleration.

What happens when reducing the number of teeth on a motorcycle sprocket?

Reducing the number of teeth on the rear sprocket tends to lengthen the final gearing, making the motorcycle less aggressive in acceleration but potentially more relaxed at higher speeds. This modification should be evaluated carefully according to engine characteristics, riding style and intended use.

Is a steel sprocket or ergal sprocket better?

A steel motorcycle sprocket prioritizes durability and resistance, while an ergal sprocket offers lighter weight and a stronger visual impact. The best choice depends on intended use, motorcycle type and the balance between durability, weight reduction and aesthetics.

Which is better for sport motorcycles: 520, 525 or 530 sprocket setup?

On sport motorcycles, the 520 chain pitch is often chosen for racing and track use because it reduces weight and friction, improving responsiveness and acceleration, although it is generally more fragile due to its reduced thickness. The 525 pitch offers a good compromise between lightweight performance, durability and sporty street use, while the 530 pitch is stronger and more suitable for powerful motorcycles, heavy road use or setups where durability and longevity are the priority. The correct choice depends on engine power, intended use, mileage and riding style.
