Engineered for precision and durability, this 14-tooth sprocket offers consistent power delivery across motocross, enduro, and trials riding conditions.

FAQs

Is this sprocket compatible with all 520 pitch chains?

Yes, this is a 520 pitch sprocket and will work with any standard 520 motorcycle chain.

Does this come with a new retaining clip or bolt?

No, the sprocket is sold as the unit itself; you should reuse your existing high-quality hardware or purchase a new OEM set if yours is damaged.

Will changing to a 14T sprocket affect my speedometer?

Yes, on many KTM models, changing the front sprocket size will cause a discrepancy in speedometer readings, which may require a recalibration device.

How often should I replace this front sprocket?

It is standard practice to replace the front sprocket whenever you replace your chain or rear sprocket to ensure even wear across the drivetrain.

Can I use this for street riding on my Duke?

Yes, the materials are robust enough for both daily street commuting and competitive off-road use.

Troubleshooting

Increased noise or vibration after installation

Check chain tension and ensure the sprocket is fully seated and properly aligned with the rear sprocket.

Difficulty sliding sprocket onto the output shaft

Clean the output shaft splines with a wire brush to remove rust or debris, then apply a thin layer of grease.

Chain jumping or skipping

This is usually a sign of an excessively worn chain or rear sprocket; replace the entire drivetrain kit for optimal performance.

  • Provides reliable power delivery compared to worn OEM parts

Setup, Compatibility & Care

To ensure peak performance and safety, follow these guidelines:

  1. Compatibility: This model is specifically for KTM LC4 Adventure and Duke series bikes (1993–2020). Always verify your motorcycle's specific drive chain pitch (520) before purchase.
  2. Installation: Secure the motorcycle on a stand, remove the sprocket cover, and use the appropriate tool to remove the retaining bolt. Slide the old sprocket off and clean the output shaft splines before sliding on the new Apico unit.
  3. Torque Specs: Always refer to your KTM owner’s manual for the specific torque requirements of the sprocket retaining bolt.
  4. Maintenance: Periodically clean the sprocket area of debris, such as mud and grit, which can cause accelerated wear. Keep your drive chain tensioned within the manufacturer's recommended specifications to avoid drivetrain strain.
