The Yamaha YZF-R1 2002 Model Specs

Overview
-	A new fuel injection system was introduced for the 2002 year, which worked like a carburetor by employing a CV carburetor slide controlled by vacuum created by the engine. With a similar power output to the 2001 bike, the engine was developed (larger bore, shorter stroke) to rev higher, faster and for longer. For 2003, the only change was the choice of colors. The previous years all had a "Red" option, but this was replaced by a black with red flames "Special Edition" which cost an extra $100. Also in 2002, Yamaha released the newly developed "Deltabox III" frame, which, with its hydro formed construction, dramatically reduced the total number of frame welds, thereby greatly improving the frame's strength and torsional rigidity. The rear end of the motorcycle was updated and streamlined with a LED taillight. This allowed for very clean rear body lines when choosing one of several common after market modifications, such as removal of the turn signal stalks and stock license plate bracket; and replacing them with assorted available replacements that "hug" the body or frame. Also, front end lighting was improved in 2002, between the higher definition headlights and also side "parking" lights within the twin-headlight panel, giving more after market possibilities to remove the front blinkers and utilize these front lights as directional or hazard markers while stopped.
