This is one cool old bike. Exhaust and swingarm are combined as a single sided swingmer, and it has cantilever suspension (monoshockish)
A guy was riding one of those around the paddock during the AHRMA races at Daytona a few years ago:up:
I remember that. It was absolutely perfect and he was 6-2, 275 lbs easy. To see that suspension operate when he took to saddle was almost scary.
