Lots of changes occurred for the 2003 model year of the YZF-R6. The biggest change on the baby R was the conversion from carburation to a new fuel injection system, similar to the R1. Body styling changed as well as new casting technology used for the frame and such. A new gauge cluster was also part of these vast updates.
