Important Fitment Information
Yamaha catalogues directly show the same oil and dust seal references on multiple YB125 model years. Verify the exact model code and original seals before ordering, especially on market-specific variants.
Yamaha part numbers are supplied for fitment identification only. This product is unbranded and is not represented as a Genuine Yamaha component.
Compare the original seal references and dimensions before ordering. Fork variants can differ by market and model revision.
What's Included
Fork oil and dust seals as supplied. Please refer to the product photographs for the exact pack quantity; the available export data does not independently confirm the number of individual seals in the pack.
Installation
Fork-seal replacement involves suspension disassembly and correct fork-oil setup. Inspect the fork tubes for corrosion or scoring before fitting new seals, as damaged tubes can quickly cause new seals to leak.
