With engine-brake control system

In developing the first generation of YZR-M1, the primary focus was on trying to achieve an easier to use engine character and chassis character. The engine format chosen was an in-line-4 because it was the format considered to have the best mutual balance with the frame and because long years of technological advances that had been made with the in-line-4. The new frame had been developed around the basic structure of the YZR500 frame that had proven itself in the GP500. The new engine began with a displacement of 942 cc and in the second
half of the season it progressed up to the full 990 cc regulation limit. One of the important technological developments was an engine-brake control system (electronic clutch) that contributed to improved handling stability in the full-throttle range. The frame design also progressed during the course of the season, with adjustment of the engine mounting position and change in the fuel tank shape. From round five, a new frame with a slightly raised engine position was introduced. The new frame featured greatly increased rigidity in the vertical direction to achieve a better balance with the torque characteristics of the in-line-4 engine. Biaggi rode this machine to two victories in the 2002 season and finished it ranked 2nd.
