Product Information

Full details

The Renthal Standard Front Sprocket (MPN: 298A-520-10P) is a high-performance drivetrain component designed specifically for Montesa 314 and 315R trials motorcycles produced between 1994 and 2004. Ideal for competitive riders who prioritize precision and durability, this sprocket is engineered to withstand the rigorous demands of technical off-road riding. One important caveat is that this specific 10-tooth sprocket is precision-machined for these vintage Montesa models and may not be compatible with other motorcycle brands or newer Montesa iterations, requiring careful verification of your bike's model year before purchase.

FAQs

Does this sprocket come with a retaining clip?

This product is the sprocket itself; always reuse your existing factory retainer or replace it if it shows signs of deformation.

Can I use this on a 2005 Montesa?

No, this part is specifically designed for 1994-2004 models. Please check your manual for the correct part number for a 2005 model.

Should I replace my chain when installing this sprocket?

It is highly recommended to install a new chain with a new sprocket to ensure they wear together evenly.

What is the gear tooth count?

This is a 10-tooth (10T) front sprocket.

Is this a steel or aluminum sprocket?

Renthal front sprockets are typically manufactured from high-strength steel to handle the high stress at the countershaft.

Troubleshooting

Difficulty seating the sprocket on the countershaft.

Ensure the countershaft splines are clean and free of debris. Do not use excessive force; check for burrs on the shaft.

Excessive noise after installation.

Check that the chain alignment is perfectly straight and ensure that the chain slack is adjusted to the manufacturer's specification.

Pros and Cons

Pros

  • Industry-leading manufacturing quality
  • Perfect fitment for specified Montesa models
  • Enhanced durability for demanding off-road use
  • Lightweight construction reduces unsprung mass

Cons

  • Limited compatibility to specific Montesa models
  • Requires mechanical knowledge for proper installation
  • Hardened surface can cause wear on old, poorly maintained chains

Setup, Compatibility & Care

To ensure maximum service life, follow these guidelines for installation and maintenance:

  1. Compatibility: This part (MPN: 298A-520-10P) is strictly for Montesa 314/315R models from 1994-2004. Do not attempt to force fit onto different spline patterns.
  2. Installation: Ensure the sprocket is secured with the manufacturer-specified locking clip or retainer. Always check the countershaft seal for signs of leaking before mounting the new sprocket.
  3. Maintenance: Regularly clean your drivetrain with approved degreasers to prevent abrasive grit from damaging the sprocket teeth. Apply a thin coat of motorcycle-specific chain lube after cleaning.
  4. Inspection: Replace the sprocket whenever you replace the chain to prevent premature wear on the sprocket teeth caused by chain elongation.
