Concept Bike Challenge - Win an Icon tee

The eighties were a wonderful time full of plastic dipped goodness. The concepts were fully faired from stem to stern and usually accompanied by ridiculous steering levers or a front swingarm. Can you identify these prime examples of one possible future? Name all five correctly with the make, model, and year and win an Icon t-shirt. As usual, post your answers in the comments section. First comment with all five correct answers wins.
