This 47-tooth precision-machined steel rear sprocket is designed for BMW motorcycles running a 520 pitch drive chain. The 47-tooth count provides a lower final drive ratio that favours stronger acceleration and mid-range torque — making it a popular replacement or upgrade option for compatible BMW models.
Key Features
- 47-tooth rear sprocket for 520 pitch chain
- Precision-machined steel construction for durability and reliable power delivery under load
- Lower final drive ratio for improved acceleration and responsive throttle feel
- Designed specifically for compatible BMW motorcycle models
What does a 47T rear sprocket do to performance?
A higher tooth count on the rear sprocket lowers the overall gearing ratio, delivering stronger acceleration and more mid-range torque at a modest reduction in maximum top speed.
