The sweetest Grand Prix racing machines ever built are no more. Starting in 2010, the 250cc two-strokes that honed the skills of world champions such as Kenny Roberts, Wayne Rainey, Freddie Spencer, Valentino Rossi, and Casey Stoner will be replaced by "Moto2" machines, a much cheaper 600cc four-stroke alternative stepping stone to MotoGP.
