FAQs
Does this sprocket come with a retaining clip?
This product listing specifically refers to the sprocket; check your bike's original hardware or service manual to see if you need a new lock washer or clip.
Can I use this on a bike that currently uses a 14T sprocket?
Yes, but be aware that changing from 14T to 15T will alter your gear ratio, potentially increasing top speed while reducing low-end acceleration.
What is the material composition?
The JT Front Sprocket is manufactured from high-quality, hardened steel alloys designed for maximum durability.
How often should I replace my front sprocket?
It is generally recommended to replace the sprockets and chain as a complete set whenever any individual component shows significant signs of wear.
Is this sprocket suitable for racing?
Yes, the precision CNC machining and high-strength alloy make this suitable for track use.
Troubleshooting
Excessive chain noise after installation
Verify that the sprocket is seated correctly on the shaft and that the chain tension is adjusted to the manufacturer's recommended slack.
Difficulty installing the sprocket nut
Ensure the sprocket is fully pressed onto the splines of the countershaft and that no debris is obstructing the threads.
Pros and Cons
Pros
- Durable steel construction
- Precise fitment matching OEM standards
- Lightweight profile reduces rotational mass
- Excellent wear resistance for long intervals
Cons
- Requires specific toolset for installation
- Must be paired with compatible chain pitch
- Requires regular lubrication for optimal life
Setup, Compatibility & Care
Before installation, verify that the 15T tooth count matches your specific motorcycle model requirements and that it is compatible with your chain pitch (e.g., 520, 525, or 530).
- Secure the motorcycle on a paddock stand.
- Remove the sprocket cover to access the countershaft sprocket.
- Utilize a high-quality socket and breaker bar to loosen the retaining nut while the rear brake is applied.
- Replace the old sprocket with the JT 726.09.38, ensuring the teeth face the correct direction.
- Torque the retaining nut to the manufacturer's specified setting.
For care, keep the chain properly tensioned and lubricated at all times to prevent excess friction, which can accelerate sprocket wear. Periodic inspection of the teeth for shark-finning (hooked appearance) is recommended during routine oil changes.
