Aprilia RS Cube

The RS Cube (often wrongly and redundantly referred as RS3 or RS3 Cube, due to the original lettering RS3) is a prototype race motorcycle that was developed by Aprilia to compete in the 2002 until 2004 MotoGP seasons. It was unveiled at the Bologna Motor Show in December 2001 by Aprilia’s president, Ivano Beggio, and their race boss, Jan Witteveen. The Cube is powered by a 990 cc inline-3 four-stroke engine (to conform to MotoGP rules of that time). The engine was developed with large F1-derived input from Cosworth, bringing many features not previously seen in motorcycle development – this includes pneumatic valves, traction control and ride-by-wire.
