The X3 (stylized as the X3) is an 800 cc V4 race bike built by Ilmor Engineering to compete in the 2007 MotoGP series.
The X3 is the brainchild of Ilmor co-founder Mario Illien and former grand prix rider Eskil Suter of Suter Racing Technology (SRT). Illien used his world championship winning F1 engine experience to design the machine's V4 powerplant, with Suter, who has previously designed Kawasaki's MotoGP chassis, in charge of the twin-spar aluminum frame.
