I wouldn't have looked twice if it wasn't for the four exhausts, two high underseats and two mounted lower... Four exhausts? Huh? Wandered over to have a squizzy and whaddya know? A suzuki RG500 2-stroke race rep of the 1980's. I don't think I've ever seen one before. It looks fascinating, and from what I've read they're quite an experience to ride as well - vicious powerband characteristics of a 2-stroke with the power of a 1980s litre bike and flyweight to boot... And notoriously unreliable. I took a couple of cameraphone shots, pm me if you want them emailed over, they're not great but will show you roughly what the thing looks like. I'm tempted to hang around near close of business to try to catch the guy starting it up... Wonder what they sound like?
