The Matris KD is a rear shock for Naked & Road bikes, of very easy use and adjust for the road rider to get a right set-up. Computerized engineering systems are used to design, project and produce all the components and only materials of high-end technical and mechanical characteristics are used. High precision machining with the objective of reducing weight and friction to offer a basic range of shocks to improve comfort, safety, and setting (always with Matris look ).Piston shaft D.16 mm made from high tensile alloy Steel, hard Chrome coated.Nitrogen gas (N2) charging valve.Fully rebuildable and revalveable.All components, machined from ALU alloy, are with anodising treatment.Made in Italy.The piston shaft used on this shock is constructed using 16mm diameter high tensive alloy steel with a hardened chrome coating, this ensures that it is weatherproof, tough and durable to last you many years of riding! It uses a nitrogen gas (N2) charging valve, which is completely rebuildable and
