The Dal Soggio 1P.KIT RAY 2016 CR RAY Kit<\/strong> is a high-performance internal upgrade developed specifically for WP 4CS front forks used in 2016 Cross\/Motocross applications<\/strong>.<\/p>\n

The RAY system was created to substantially change the way the original WP 4CS fork operates rather than simply altering the standard shim settings.<\/p>\n

Once installed, the kit reorganizes the internal damping functions by positioning compression control in the lower section<\/strong> and rebound control in the upper section of each fork leg<\/strong>.<\/p>\n

This revised architecture allows both fork legs to contribute more effectively to hydraulic damping and significantly changes oil management inside the WP 4CS system.<\/p>\n

A key feature of the RAY concept is the increase in hydraulic flow through the shim system. According to Dal Soggio, the kit doubles shim oil flow<\/strong>, allowing the suspension to react in a more natural and controlled manner.<\/p>\n

The objective is to improve fork sensitivity, damping precision, comfort, and rider feedback while retaining the original WP 4CS fork assembly.<\/p>\n

The RAY Kit is designed for riders who want a substantial improvement in their original suspension without replacing the complete fork or installing a full cartridge system.<\/p>\n

    Kit Contents<\/h3>\n

    The RAY Kit<\/strong> includes:<\/p>\n

      \n
    • 2 assembled compression units<\/strong><\/li>\n
    • 2 pins with rebound calibration<\/strong><\/li>\n
    • 2 compression clickers for installation on the upper caps<\/strong><\/li>\n
    • 2 adjusters to increase spring preload<\/strong><\/li>\n<\/ul>\n

      These components work together as a complete hydraulic conversion rather than as isolated replacement parts.<\/p>\n

      <\/h3>\n

      <\/h3>\n

      How the RAY Kit Works<\/h3>\n

      The original WP 4CS fork uses a particular four-chamber hydraulic architecture.<\/p>\n

      The RAY Kit modifies this architecture by reorganizing the damping functions inside both fork legs.<\/p>\n

      After installation:<\/p>\n

        \n
      • compression damping is managed in the lower portion of each leg;<\/li>\n
      • rebound damping is managed in the upper portion of each leg;<\/li>\n
      • both fork legs participate more effectively in the damping process;<\/li>\n
      • shim oil flow is increased.<\/li>\n<\/ul>\n

        Dal Soggio states that this arrangement allows the fork to operate more naturally and with reduced friction, helping improve sensitivity and suspension response.<\/p>\n

        <\/h3>\n

        <\/h3>\n

        Suspension Behavior<\/h3>\n

        The RAY system is designed to improve the behavior of the WP 4CS across varying terrain and riding speeds.<\/p>\n

        The intended benefits include:<\/p>\n

          \n
        • improved initial sensitivity;<\/li>\n
        • more accurate damping response;<\/li>\n
        • smoother reaction over small and square-edge impacts;<\/li>\n
        • improved front-wheel feedback;<\/li>\n
        • greater hydraulic support during larger suspension movements;<\/li>\n
        • improved rider comfort and control.<\/li>\n<\/ul>\n

          <\/h3>\n

          <\/h3>\n

          Application & Compatibility<\/h3>\n

          The 1P.KIT RAY 2016 CR<\/strong> is intended specifically for 2016 WP 4CS Cross\/Motocross applications<\/strong>.<\/p>\n

          Dal Soggio separates the RAY range into different versions for:<\/p>\n

            \n
          • WP 4CS 2013-2015;<\/li>\n
          • WP 4CS 2016;<\/li>\n
          • WP 4CS 2016 MX\/Cross.<\/li>\n<\/ul>\n

            Because the internal configuration can differ between these versions, the correct RAY Kit must be selected according to the exact fork specification.<\/p>\n

            <\/h3>\n

            <\/h3>\n

            Installation Note<\/h3>\n

            Installation requires disassembling both WP 4CS fork legs and fitting the complete RAY hydraulic conversion components.<\/p>\n

            Correct assembly, shim configuration, oil filling, bleeding, compression-clicker installation, preload adjustment, and final suspension setup are essential for proper operation.<\/p>\n

            Dal Soggio recommends installation and setup by a qualified suspension technician or authorized specialist<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
