Apico Rear Sprocket - Yamaha YZ65 2018-2023 - 46T

The sprocket is manufactured from aerospace-grade C45 Medium Carbon Steel.

This variant has a tooth count of 46T.

No, this sprocket is specifically designed for Yamaha YZ65 models from 2018 to 2023.

The clearing grooves are designed to help remove build-up of mud and debris from the sprocket and chain, which reduces wear and maintains optimal performance.

This coating provides a unique aesthetic finish and offers excellent anti-corrosive properties, protecting the steel from rust and environmental damage.

The CNC machining and laser-cut profile are designed for improved weight reduction and strength compared to standard sprockets, though it is made of steel which may be heavier than some aluminum aftermarket options.

It is recommended to clean the sprocket and chain after each ride, especially if riding in muddy or dirty conditions, to ensure longevity and performance.

Verify you have the correct model year (2018-2023) and bike model (Yamaha YZ65). Ensure the sprocket is seated properly on the sprocket carrier and that no debris is obstructing the mounting holes.

Check chain tension; it may be too tight or too loose. Ensure the chain and sprocket are properly lubricated. Inspect for bent or worn chain rollers or sprocket teeth.

Ensure the chain is properly aligned and lubricated. Clean mud and debris regularly, especially from the clearing grooves. If wear is uneven, check the sprocket carrier for damage or runout.

While the Cataphoresis Electro Coating provides excellent protection, prolonged exposure to harsh elements without cleaning can still lead to surface rust. Clean thoroughly with a mild degreaser and reapply chain lubricant.
