FAQs
Is this sprocket compatible with an OEM chain?
Yes, it is designed as an exact replacement for OEM parts and is compatible with standard chain sizes used on the supported Honda models.
What does the 52T designation mean?
The 52T indicates that the sprocket has 52 teeth, which generally provides more low-end torque and acceleration compared to a sprocket with fewer teeth.
Do I need to replace my chain when installing this sprocket?
It is highly recommended to install a new chain with a new sprocket to ensure all components wear evenly and maximize the life of your drivetrain.
How does the Cataphoresis coating affect performance?
The coating primarily improves the corrosion resistance and durability of the steel, ensuring the sprocket remains protected from the elements.
Can I use this for street riding?
While technically compatible with some XR models that see dual-sport use, this sprocket is optimized specifically for motocross and enduro performance.
How often should I clean the sprocket?
You should clean and lubricate the sprocket and chain after every ride, especially if you have been riding in muddy or sandy conditions.
Troubleshooting
Excessive chain noise after installation
Check that the chain is correctly aligned and the tension is within the bike's service manual specifications.
Sprocket appears to be wobbling
Ensure all mounting bolts are tightened evenly in a star pattern and that no dirt or debris is trapped between the hub and the sprocket.
Premature tooth wear
Verify that your chain is not stretched beyond its wear limit; a worn chain will rapidly damage a new sprocket.

Setup, Compatibility & Care
This sprocket is designed as a direct replacement for various Honda models, including the CRF250R, CRF450R, CR125, CR250, CR500, and several XR/CRF-X variants.
Installation Steps:
- Secure the motorcycle on a stand and remove the rear wheel.
- Unscrew the existing sprocket nuts and remove the old unit.
- Clean the hub mounting surface thoroughly before installing the new Apico sprocket.
- Ensure the sprocket is seated evenly and tighten the nuts in a star pattern to the manufacturer-specified torque settings.
- Verify that your drive chain is properly tensioned and lubricated for the new sprocket profile.
Maintenance: While the Cataphoresis coating is corrosion-resistant, regular cleaning after rides and the application of high-quality chain lubricant is essential to prevent rust and extend the lifespan of both the chain and sprocket teeth.
