The Athena S41TE46K Inner Fork Bushing External PTFE<\/strong> is a replacement sliding bushing designed for compatible Kayaba \/ KYB 46 mm motorcycle front forks<\/strong>.<\/p>\n

The bushing uses a high-strength steel body<\/strong> capable of withstanding the repeated mechanical loads generated during fork compression and rebound.<\/p>\n

The external working surface is coated with PTFE (polytetrafluoroethylene)<\/strong>, a low-friction material designed to reduce sliding resistance and minimize wear between moving suspension components.<\/p>\n

This low-friction interface helps the fork move more smoothly through its travel and contributes to maintaining consistent suspension response over time.<\/p>\n

The inner side of the Athena bushing uses a copper coating<\/strong>, selected for its thermal conductivity and corrosion resistance. The copper layer helps distribute heat generated during suspension operation while providing additional protection against oxidation.<\/p>\n

The published dimensions for S41TE46K are 45 \u00d7 47 \u00d7 20 mm<\/strong>, corresponding to the compatible Kayaba 46 mm bushing configuration.<\/p>\n

Each package contains one bushing<\/strong>, suitable for servicing one fork leg. For a complete two-leg fork overhaul, a second identical S41TE46K bushing is required together with the corresponding internally PTFE-coated bushings used in the same fork assembly.<\/p>\n

    PTFE Low-Friction Surface<\/h3>\n

    The external PTFE coating creates the primary sliding interface of the bushing.<\/p>\n

    Reducing friction at this point helps:<\/p>\n

      \n
    • improve fork smoothness;<\/li>\n
    • reduce sliding resistance;<\/li>\n
    • minimize surface wear;<\/li>\n
    • support better suspension sensitivity;<\/li>\n
    • maintain consistent fork action over repeated cycles.<\/li>\n<\/ul>\n

      <\/h3>\n

      <\/h3>\n

      Copper-Coated Inner Surface<\/h3>\n

      The internal copper coating helps distribute heat generated during suspension movement.<\/p>\n

      Copper also contributes to oxidation and corrosion resistance, supporting component durability during long-term suspension use.<\/p>\n

      <\/h3>\n

      Service Quantity<\/h3>\n

      Each package contains:<\/p>\n

      1 \u00d7 Athena S41TE46K Fork Bushing<\/strong><\/p>\n

      One bushing services one fork leg<\/strong>.<\/p>\n

      For a complete fork overhaul, two S41TE46K bushings are required together with the corresponding Kayaba 46 mm internal-PTFE bushings<\/strong>.<\/p>\n
