Based in Italy, CR&S (Café Racers and Specials) are doing what Italians do best – building whacky motorcycles that look and feel a bit special. The spec is not that impressive – the Vun is powered by a 4-valve, DOHC, 652cc, single-cylinder, liquid-cooled Bombardier-Rotax engine that makes a mere 54 horsepower. But since the bike only weighs 135kg dry, performance is entertaining.  For those who think 54bhp may be a bit much, there’s also an ‘underpowered’ 29bhp version (that’s what the factory website says it is!) available, as is a 68bhp racing version, which is for track use only. All versions of the Vun are, however, fitted with a steel-tube chassis, Ceriani 46mm front forks, adjustable Paioli monoshock rear suspension and 320mm single-disc brakes at the front. Prices start at around US$20,000 for the basic Vun, and there’s a near endless options list for those who want to spend more money.

The Vun is designed with minimum weight in mind, to this end the bike uses an underslung exhaust as used on Buell bikes.
One of the main advantages of this design is that it keeps weight low down and lowers the center of gravity a vital component of good handling.

CR&S is a small company of around ten individuals. Roberto Crepaldi, one of the company's cofounders was a close friend of John Britten, a man who created one of the most radical bikes of the century the Britten V1000. The Vun pays homage to this visionary who died in 1995.
