Take a look at the pictures from this years Concorso d Eleganza held at Lake Como Italy. My favorite bike in this collection of photographs is the 1969 Kawasaki Mach III 500. If you have never heard a two stroke triple on the pipe you have really missed something. Of course I grew up riding two strokes and I love their simplicity, performance, and how easy they are to work on. That Ducati 50CC Scrambler is pretty neat too and it is a two stroke also.
