This 49-tooth precision-machined steel rear sprocket is designed for motorcycles running a 520 pitch drive chain. With a high tooth count, it provides a significantly lower final drive ratio — delivering strong acceleration and aggressive low-to-mid range torque, making it well-suited to off-road, motocross, and performance street applications.
Key Features
- 49-tooth rear sprocket for 520 pitch chain
- Precision-machined steel for durability and efficient power transmission
- A high tooth count provides a lower final drive ratio for strong acceleration and torque
- Suitable as a direct replacement or performance gearing upgrade
What does a 49T rear sprocket do to performance?
A 49-tooth rear sprocket significantly lowers the overall gearing ratio, maximising acceleration and low-end torque at the expense of top-end speed — ideal for technical riding, off-road use, or any application where strong bottom-end response is the priority.
Frequently Asked Questions
What chain pitch does this suit? Designed for 520 pitch chains. Always confirm your existing chain pitch before purchasing.
What does D/D mean? D/D refers to Drive/Driven — confirming this is a driven (rear) sprocket specification.
Should I replace my chain and front sprocket at the same time? Yes. Replacing the complete drivetrain together ensures even wear and maximises component longevity.
