Like original OEM fork internals many aftermarket cartridges are manufactured with non-anodized aluminum and/or mild steel components. It is important to compare the K-Tech design and manufacturing philosophy which goes the extra mile utilizing all hard anodized aluminum or hard chromed steel internal components. This detail reduces contaminants that build up in the fork fluids which reduces maintenance, prolongs durability and increases consistency of performance. Typically, users are surprised to see clean oil emerge when performing scheduled fork maintenance rather than dark, contaminated oil.
K-Tech DDS (Direct Damping System) front fork cartridges are a complete replacement damping system designed and manufactured in the UK for high end racing applications. The DDS cartridge is a pressurized damping system using 20mm displacing pistons to create a high flow of oil through the 31mm control valves to give precise damping control. The patent design eliminates cavitation making the system very stable under extreme conditions, the damping circuits are designed to work independently to improve the dynamics and response time. The system is pressurized by a spring force keeping it stable under all working temperatures.
