The FZ6 Fazer S2 and FZS S2 motorcycles were launched by Yamaha in 2007 and included technical, functional, and design modifications that enhanced their overall specifications. The S2 models offered more technology, style, and performance than the standard model.
Some of the modifications featured by the FZ6 Fazer S2 included a new, high-specification lightweight aluminum swingarm made of hexagonal cross sections associated with the matching aluminum frame.
The front brake caliper was a single-piece high-specification unit that came in a compact, lightweight, and rigid form, offering excellent braking performance and feel, topped by accurate control.
For ergonomics, the aluminum passenger footpegs were placed lower for a more relaxed riding position. At the same time, the front cowl and windscreen were redesigned, offering a sportier character, high-speed comfort, and reduced fatigue.
In the performance department, the Yamaha FZ6 Fazer S2 packed a remapped fuel injection system, offering more performance characteristics and better throttle response at higher engine speeds.
For power, the bike was fitted with a 599cc four-stroke four-cylinder liquid-cooled engine fed by an electronic fuel injection system, delivering an output power of 98 hp with maximum strength at 12,000 rpm and 63 Nm (46 lb-ft) torque at 10,000 rpm.
The gases produced by the engine were diverted through a four-into-two-into-one exhaust system, with an appearance similar to its predecessors but with different internals, including three honeycomb catalyzers and an oxygen sensor.
