FAQs
Is this sprocket compatible with a 2019 Yamaha YZ65?
Yes, this part is compatible with all Yamaha YZ65 models produced from 2018 through 2025.
Does this come with a retaining clip or bolts?
No, this product is the sprocket unit only. You should reuse your existing mounting hardware or replace it with new OEM-spec components.
How often should I replace my front sprocket?
It is standard practice to replace the front sprocket whenever you replace your chain, or every 20-30 hours of rigorous track use, depending on riding conditions.
What is the material composition of this sprocket?
It is made from Japanese SCM420 chromoly steel alloy, which is known for its high strength and durability.
Will a 14T sprocket change my bike's gearing?
The 14T is typically the stock tooth count for this model. Changing to a different tooth count would alter the bike's final drive ratio, affecting acceleration and top speed.
Troubleshooting
Excessive noise or clicking during acceleration
Check chain tension; a chain that is too tight or too loose can cause improper engagement with sprocket teeth.
Difficulty fitting the sprocket onto the countershaft
Ensure the splines on the countershaft are clean and free of debris. Do not force the sprocket; check for burrs on the shaft.

Setup, Compatibility & Care
This sprocket is engineered specifically for Yamaha YZ65 models ranging from 2018 to 2025. Installation should be performed by a qualified technician or an experienced enthusiast using standard shop tools.
- Ensure the bike is stabilized on a stand.
- Remove the sprocket cover to access the countershaft.
- Secure the rear wheel or use a gear-locking tool to prevent rotation during removal.
- Replace the old sprocket, ensuring the splines align perfectly.
- Torque the retaining nut to the manufacturer's specified setting.
For care, periodically inspect the teeth for signs of hooking or "shark-finning." Keep the chain clean and properly lubricated to prevent premature wear on the sprocket teeth.
