The Yamaha FZ6 was a middleweight street machine that debuted in 2004, also known as the FZ6 Fazer, powered by a retuned version of the 2003 YZF-R6 powerplant. The bike was replaced by the 2010 fully-faired FZ6 R in North America and Europe by the XJ6 Diversion, XJ6 N, and XJ6 Diversion F.
The bike was popular due to its half-fairing, upright riding position, and under-seat exhaust system. It was designed as a multi-purpose machine with touring, commuting, and sport riding capabilities.
In 2006, the bike received its first revision, with a blacked-out engine, frame, subframe, grab handles, swingarm, and wheels. Also, it was fitted with a metal honeycomb catalytic converted to meet Euro2 and carb emission standards and an upgraded fuel injection system for more torque at lower rpm.
In 2007, the Yamaha FZ6 received its second revision that included an optimized fuel injection system mapping, a redesigned fairing and windscreen, a new instrument panel similar to the FZ1's machine, four-piston calipers on the front, a new catalytic converter, a redesigned seat, a new swingarm, and new passenger footpegs.
The front stopping power was now achieved by four-piston calipers with two 298 mm floating discs, while the rear braking performance remained unchanged, with a 245 mm disc and a single-piston caliper.
As for power, the 2007 Yamaha FZ6 delivered the same performance as its predecessors, with 98 hp at 12,000 rpm and 63 Nm (47 lb-ft) torque at 10,000 rpm from a 599cc four-stroke four-cylinder liquid-cooled engine.
