Aprilia RS3 Cube 2002-04

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, Tracion Control and ride-by-wire.
The bike was not a success; Colin Edwards proclaimed the bike was "born bad," and it had "just so many things that need fixing." It had a tendency to wheelie easily, a lack of front-end feel, vibration from both the front and rear wheels, and unpredictable response from its fly-by-wire throttle system. Edwards' teammate in the 2003 Aprilia team, Noriyuki Haga, crashed the Cube 28 times in a single season.
The engine was considered the most powerful at that time, producing about 240 bhp (180 kW).[citation needed] A testbed that never was raced produced 260 bhp (190 kW) at one point, before Aprilia bowed out of MotoGP in 2004.
