Generation Overview:
The YZF-R6 was introduced in 1998 as a revolutionary 600cc supersport. The 1999-2007 period covers several significant updates and refinements to the original design, including major engine and chassis changes for different model years (e.g., RJ03 1999-2002, RJ05 2003-2004, RJ09 2005-2006, RJ11 2006-2007). The early models featured carbureted engines, while later models transitioned to fuel injection and more advanced electronics. The 2006 model year saw a significant redesign with a 130 HP engine and underseat exhaust. The 2007 model continued this evolution with further refinements.
Production Location:
Primarily Japan
Sales Significance:
The YZF-R6 has consistently been a top seller in the 600cc supersport class, prized for its racing pedigree and performance capabilities, making it a popular choice for both street riders and track enthusiasts.
