The Yamaha FZ6 is a 600 cc motorcycle that was introduced in 2004 as a sporting middleweight sport bike built around the 2003 YZF R6 engine. The engine is retuned for more usable midrange power. It comes with a somewhat soft suspension that makes it easy on beginners and very well suited for sport-touring, commuting, or just having fun on curvy mountain roads.

The 2009 model (introduced on September 08, 2008) is technically unchanged from 2008/2007. The available colours for 2009 are Raven and Deep Blue (Metallic Black and Metallic Purplish Blue in Canada / Midnight Black, Ocean depth and Silver Metallic in Europe). European model ‘FZ6 Fazer S2 ABS’ has ABS and electronic immobilizer as standard. It is also 5 kg heavier (Dry Weight 191 kg).

Yamaha also produces a bigger 1000 cc version of this motorcycle called the Yamaha FZ1. There is also an entry level version of this bike which is Yamaha FZ6R.

Price: $7,290

Key Features:
