ULTRA high-powered sports cars  supercars  are considered by many to be the highest expressions of vehicular performance. Schoolboys, young and otherwise, dream of Ferrari Enzos, Porsche Carrera GTs, Lamborghini Gallardos, Ford GTs and Corvette ZR1s.

The implication, given the cars’ prices of $100,000 to over $2 million, is that they are the quickest, most responsive, fastest-cornering street machines ever.

It just doesn’t happen to be true. All those cars can be humbled, in nearly any measure of real-world performance, by a dozen or so street-legal, completely stock, easily available motorcycles.
