BMW R1200GS Adventure LC mirror extenders Ztechnik Z5202 for use with certain Windshileds V Stream- ZTechnik adds a new twist to a familiar design. The windshield experts introduce LeverAction, a trick replacement kit that obsoletes the knob-and-nut hardware on the R1200GS Adventure windshield. ZTechnik wants to enhance every mile you spend on your R1200GS Adventure by making your equipment work easier with enhanced functionality. To that end, ZTechnik developed LeverAction, a slick looking, injection molded lever that replaces the chunky rake adjustment knobs. LeverAction combines the shaft and nut of the traditional windshield adjustment hardware into a one-piece design, eliminating the possibility of nuts getting loose and falling into your motorcycle. A quick flip of the lever is all it takes to disengage the windshield -- within seconds you will have your screen in its new position and be back on the road! ZTechnik's LeverAction Kit works great with both BMW and ZTechnik windshields and is made of nylon plastic and stainless steel for long lasting durability and high-tech good looks. Material: Injection Molded Nylon Plastic with Stainless Steel Hardware. Hardware: Direct Replacement for Existing Parts. All Hardware Included.
