Tall Dave Johnson came with a new fairing for his SWB bike.On a table top it looks like it is too shallow, but it sits at an angle on the bike, and works well.
It is made of coroplast with one big panel wrapped in a U around the front and sides plus 8 or so narrow facetted panels to make up the pseudo-curved top. Mountings and bracing are made of aluminum. The panels are held together with zip ties and tape.
He added a small windscreen with plastic tubing edges, but it is too heavy and will be replaced with an improved version soon.
