Most everyone is familiar with the old Vetter fairings that found their way on to almost every two wheeler at some time or other, but many other companies have produced fairings of their own design and I just ran across one that’s new to me, it’s called a Jacwal Superwedge. This one is mounted on a 1978 Yamaha XS1100 for sale on eBay and the owner says the fairing is from the same era. The advertisement here shows a Kawasaki Z1 outfitted with lots of things from the same company, including an auxiliary fuel tank that attaches behind the seat and “Supermirrors” that mounted to the Superwedge fairing.
The design might not suit everyone’s tastes but it is interesting, with a fixed lower portion and an upper windshield and hand guards that rotate with the handlebars. It actually looks like it would be pretty effective and might increase mileage somewhat. The company was located in California. Different and kinda neat.
