The Yamaha FZ6, also known as the FZ6 FAZER, is a 600 cc (37 cu in) motorcycle that was introduced by Yamaha in 2004 as a middleweight street bike built around the 2003 YZF-R6 engine. The engine is retuned for more usable midrange power. As a multi-purpose motorcycle it can handle sport riding, touring, and commuting. In 2010, the FZ6 was replaced by the fully faired FZ6R in North America, and the XJ6 in Europe. The FZ6 styling was continued in 2011 with the Yamaha FZ8.
