Full details
The JT Steel Sprocket 13T is designed for motorcycle enthusiasts and mechanics looking for a reliable, high-performance drivetrain component that balances durability with weight efficiency. Engineered using advanced steel alloys, this sprocket is an ideal choice for riders who demand consistent power transfer and long-term wear resistance. While it offers exceptional structural integrity, users should verify that their motorcycle's chain pitch and mounting requirements match the 13-tooth specification before purchase to ensure proper gear ratio and fitment.

FAQs
What does the 13T designation mean?
The 13T designation indicates that the sprocket has 13 teeth.
How often should I replace my front sprocket?
It is standard practice to replace the front sprocket, rear sprocket, and chain as a complete set to ensure uniform wear and optimal performance.
Is this sprocket compatible with all motorcycle chains?
No, you must ensure the sprocket's tooth pitch matches your motorcycle's chain size (e.g., 520, 525, or 530 pitch).
Does this sprocket come with mounting hardware?
No, the package typically includes only the sprocket. You should reuse your existing mounting hardware or replace it if the bolts show signs of wear.
Can I install this on a different bike model?
Only if the countershaft spline dimensions and chain pitch specifications are identical to the model it was designed for. Always check your bike's parts manual.
Troubleshooting
Excessive noise during acceleration
Check chain tension and ensure the sprocket is properly seated and aligned with the rear sprocket.
Rapid tooth wear
Inspect the drive chain for elongation or stiff links; replace the chain if it does not match the pitch of the new sprocket.
Difficulty fitting sprocket onto shaft
Clean the countershaft splines of any debris or oxidation and ensure the sprocket is oriented correctly.
Pros and Cons

- Professional installation recommended to prevent misalignment
Setup, Compatibility & Care
Installation of the JT Steel Sprocket should be handled by a qualified technician or an experienced rider. Begin by removing the sprocket cover and securing the motorcycle on a stand. Ensure the transmission is in neutral to allow the countershaft to rotate freely while loosening the retaining hardware. When installing, ensure the sprocket is seated correctly on the splined shaft. Always inspect your drive chain for signs of stretch or damaged links, as using a new sprocket with a worn-out chain will lead to premature wear of the sprocket teeth. For maintenance, clean the sprocket periodically to remove road grit and debris, and apply a high-quality motorcycle chain lubricant to ensure smooth contact between the chain rollers and the sprocket teeth.
