Vins Duecinquanta Sport
The Vans Duecinquanta is, as far as I know, still at the prototype stage, so may never see the light of day. It's got a wide angle 250cc V-twin two stroke engine,
housed in a carbon fibre monocoque frame with a BMW like front end and a horizontally mounted rear shock.
Only information I could find is on their website, which is in Italian (which I cannot understand.)
If this ever see the light of day, it's bound to be expensive (one website put the price as around £35,000 = 39,000 Euros = US$47,000), and therefore very rare. Also how a 2 stroke would get round current emissions regulations is anyone's guess.
