The CPRV (Cusco Pressure Relief Valve) system is a pressure-dependent design that automatically compensates hydraulic fluid flow for optimal dampening rates, preventing the piston speed from falling below a sufficient comfort level. This advanced technology ensures consistent performance across all driving conditions, from daily street driving to spirited weekend track use.
