I have built a custom swingarm bike (named Stardust) where the rear fender was attached (welded) to the swingarm. Advantage: you can place the fender very close to the tire which always look better (like with a hardtail frame). Of course, the solo seat pan must be off the rear fender with enough clearance for the swingarm/fender to move freely. But Stardust was a solo seat bike. This picture shows the new 2008 Harley Rocker FXCWC being ridden with a passenger. I like the new Harley Rocker, but as a designer, I have difficulties assimilating this passsenger riding position. For me, the new Harley Rocker should be a solo seat bike. Your reaction?
