This large luggage rack was designed with the Honda Valkyrie Interstate in mind but fits perfectly on the Honda GL1800 Gold Wing as well as the GL1500 Gold Wing. The manufacturer's trunk specs should be referenced for loading limits. Dimensionare 24"L x 13"W x 7 1/2"H. The hardware comes with tapered stainless steel spacers that allow the rack to easily conform to the curve of almost any trunk. These specially designed washers are recessed to allow the rack feet to sit into the spacer spreading the load over the trunk lid more equally. Rubber washers assure a water tight fit to the trunk lid. Works with OEM spoiler.
