It's the SLC K200, an italian micro-supercar, made by Superlight Cars, a subsidiary of the ATR Group, best known for supplying carbon-fiber body for the Ferrari Enzo, Porsche Carrera GT or Bugatti Veyron ! First shown in 2001, this little wonder used a tailor-made 350 cc twin-cylinder, with 20 hp and paddle-shift gearbox. It had scissor-doors too, but the eye-watering price (around 28 000 € !) didn't help, and very few were built.
It was more a kind of sinthesis of ATR skills...
