Replace the plain plastic reservoir covers with these beautifully machined aluminum replacement caps. They have a beadblasted, durable hard-anodized grey finish to match the Boxer's cylinder head covers. Precise tolerances ensure a perfect and exact fit. Anti-rotational threads hold our ZCaps more securely than other aftermarket replacement caps, aligning and gripping the OEM reservoir's locking detents. Complete the look with our ZTechnik Machined Aluminum ZPlugs! Machined aluminum with beadblasted finish and hard-anodized grey colour. Includes removal/installation tool for OEM and ZTechnik reservoir covers.
