The RCU Designs Accessory Shelf for the R1100RT is ideal for mounting a radar detector, GPS unit, a garage door opener or whatever you might think of that will mount on the 4” x 10” surface. The shelf is supported directly over the speedometer and tach and protrudes over the front edge of the dash by four brackets. Shelf and brackets are machined from aircraft-quality, aluminum alloy and painted in black powder coat for an unbelievably tough and long-lasting finish. Screws and nuts are black, zinc-plated for corrosion resistance. The shelf can be easily drilled to mount your accessories or many users have found that adhesive-backed, industrial-strength, hook and loop material will satisfy their needs. A side benefit is the shading provided by the shelf to reduce the suns glare on your instruments plus the reduction of the instrument lighting glare on your windshield. The two cutouts give tall riders visibility to the top of the instruments. There is no interference with the windshield adjustment. There are no holes to drill as existing holes are used for all brackets.
