The Athena S41TE48S Inner Fork Bushing External PTFE<\/strong> is a replacement sliding bushing developed for compatible Showa 48 mm motorcycle front forks<\/strong>.<\/p>\n

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

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

This low-friction surface supports smoother telescopic movement and helps maintain consistent suspension response as the fork moves through its travel.<\/p>\n

The inner surface is finished with a copper coating<\/strong>, providing good thermal conductivity and additional protection against oxidation and corrosion.<\/p>\n

The combination of steel, external PTFE, and internal copper is designed to provide durability, smooth operation, and consistent performance during demanding suspension use.<\/p>\n

Each package contains one bushing<\/strong>, suitable for servicing one fork leg. A complete two-leg fork overhaul requires a second identical S41TE48S bushing together with the corresponding internally PTFE-coated bushings used in the Showa 48 mm fork assembly.<\/p>\n

    <\/h3>\n

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

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

    PTFE is used to reduce friction between the fork’s moving components, helping provide:<\/p>\n

      \n
    • smoother compression and rebound movement;<\/li>\n
    • reduced sliding resistance;<\/li>\n
    • lower wear at the bushing interface;<\/li>\n
    • consistent fork response through repeated suspension cycles.<\/li>\n<\/ul>\n

      Maintaining a low-friction interface is particularly important in front suspension systems because excessive friction can reduce sensitivity to small bumps and affect overall fork movement.<\/p>\n

      <\/h3>\n

      <\/h3>\n

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

      The inner side of the bushing uses a copper coating.<\/p>\n

      Copper provides good thermal conductivity, helping distribute heat generated during suspension operation.<\/p>\n

      The coating also contributes to protection against oxidation and corrosion, supporting long-term durability under demanding riding and environmental conditions.<\/p>\n

      <\/h3>\n

      <\/h3>\n

      Service Quantity<\/h3>\n

      Each package contains:<\/p>\n

      1 \u00d7 Athena S41TE48S Fork Bushing<\/strong><\/p>\n

      One bushing is required for one fork leg<\/strong>.<\/p>\n

      For a complete service of both fork legs, two S41TE48S bushings are required together with the corresponding Showa 48 mm internally PTFE-coated bushings<\/strong>.<\/p>\n

      The complementary internal-PTFE bushing should be selected according to the exact fork specification.<\/p>\n

      <\/h3>\n

      <\/h3>\n

      Application & Compatibility<\/h3>\n

      The S41TE48S<\/strong> is designed for compatible Showa 48 mm front forks<\/strong> using the corresponding 47 \u00d7 49 \u00d7 20 mm bushing specification.<\/p>\n

      Compatibility should be verified from the actual fork fitted to the motorcycle, particularly if the suspension has previously been replaced or modified.<\/p>\n","protected":false},"excerpt":{"rendered":"
