Description
Cycle proudly introduces a revolution in windscreen performance!
To offer a quiet, comfortable ride, other manufacturers will offer taller windshields or spoiler tops to lift the air stream. Cycle designed, for the first time , a windshield with airflow calculated and adjusted to really quiet the riders environment.
The typical airflow pattern of the wake from most windshields is called a van Karman vortex. At speeds of 50-90 mph, the air swirls off the windshield in an approximate 90-degree segment of rotation. It off the windshield, hits the bottom of the riders neck on the way up, and curves off the shoulder at approximately 45 degrees. Cycle gave the VStream its name for the shape it takes at the upper edge.
The V shape is so outstandingly quiet because it pushes this vortex out and away more than 4 inches from the side of the riders . The riders helmet then resides in still air, and the passengers environment is greatly improved as well.
