YZ 85/65 High-Low Compression Adjuster

High Speed Compression adjustment for KYB Yamaha Mini shocks.  This transforms the shock action , improving high speed spike straight away due to its internal design but also allowing further tuning by adding or reducing spring preload to the shim stack via our external 12mm Hex adjuster.  Low speed comp remains the same, slot screw adjustment in 'clicks'.   A must to upgrade these shocks for the serious mini racer .
