K-Tech Suspension 25 RDS Fork Cartridge Kit
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.
