It is the standard CVO Road KIng Shield. It can be ordered from HD. It is the only one they sell with a vent. It is definitely lower than the medium, 21" touring shield. The vent offers a great option to increase a little breeze and reduce buffeting
My new to me 2011 Road King. Bike was used for 5,000 miles by Ann Arbor PD before getting into my hands. Coming from a HD sportster, this thing rides like a dream. Already took the seat and its air system off and put a two-up seat on it. Spring can't come soon enough.
