The inside has four detents machined into the sidewalls to allow exact ¼ turn adjustment in lieu of the ½ turn adjustment available with the stock cap. Designed to fit the adjustment cylinder of the R1150GS, a hexagonal insert allows attachment to the smaller hex found on the R1200GS adjustment cylinder.
This is a beautiful piece you will be proud to display on your BMW with the adhesive-backed roundel setting off the top of the plug and hiding the included attachment screw.
