This 42-tooth precision-machined steel rear sprocket is designed for motorcycles and ATVs running a 525 pitch drive chain. It serves as a direct replacement or performance upgrade, with the 42-tooth count providing a lower final drive ratio that favours stronger acceleration and torque over top-end speed.
Key Features
- 42-tooth rear sprocket for 525 pitch chain
- Precision-machined steel for strength, durability, and accurate tooth profile
- Lower gearing ratio for improved acceleration and mid-range torque
- Suitable for motorcycles and ATVs using a 525-pitch chain
What does a 42T rear sprocket do to performance?
Fitting a larger rear sprocket lowers the final drive ratio, delivering stronger acceleration and more responsive low-to-mid range power. This comes at a modest reduction in maximum top speed — a popular trade-off for street, sport, and canyon riding.
Frequently Asked Questions
What chain pitch does this suit? This sprocket is designed for 525-pitch chains. Always confirm your existing chain pitch before purchasing.
How does 42T compare to a smaller rear sprocket? More teeth means lower gearing — better acceleration and torque at the expense of a slight top speed reduction.
Should I replace my chain and front sprocket at the same time? Yes. Replacing the complete drivetrain together ensures even wear and maximises the service life of all components.
