This air filter is an essential upgrade for any YZ125 rider looking to enhance their bike's engine performance and ensure optimal filtration of the incoming air.

The UNI Filter NU-2243 is engineered using the latest technology and materials to provide superior air filtration.

Installation of the UNI Filter NU-2243 is straightforward and can be completed quickly and easily by following the steps in your motorcycle's service manual. The filter comes in an OEM-size and shape, ensuring a perfect fit for your Yamaha YZ125. Additionally, the filter includes an oil priming tool to help facilitate the initial installation process.

In summary, the UNI Filter NU-2243 is an excellent investment for any Yamaha YZ125 rider from 1979. Its advanced filtration capabilities, durability, and ease of maintenance make it a must-have upgrade for those looking to maximize their bike's performance and ensure optimal engine protection.
