Use on STOCK GL1800. Won't fit with handlebar risers or setbacks that alter the geometry of the stock handlebar if the distance between the 4 hex bolts behind the plactic covers on the handlebar clamps changes. The Space Station provides a flexible, ample space to mount nearly anything you can imagine. Aircraft aluminum, anodized black for long life and durable operation. Adjustable and configurable, it is compatible with many drink-cup mounts and other mounts that use the Wing's handlebar brackets. Supplied with mounting hardware, wire management supplies, instructions and plenty of Dual Lock to fasten most anything with a flat surface. Ed uses his Garmin 2610 on a Space Station at all speeds (tested well beyond all reason!) in all weather and even while running from wild Buffalo in the Dakotas with nary a worry of it coming off.
