The 2013 Yamaha FZ1 was a sports machine part of the second generation of FZ1 motorcycles that debuted in 2006 as a completely new model from the first generation, which was manufactured from 2001 to 2005.
The first models manufactured from 2001 to 2005 were identical without any changes except for color alterations. The 2006 machine came in a completely new package, with a new chassis, bodywork, suspension, and engine.
Over its production years, the second generation featured several modifications, such as the 2006 model that came with a stiff rear shock spring and a distinct throttle snatch at 5,000 to 6,000 rpm.
The 2007 Yamaha FZ1 featured a softened rear spring and an updated fuel injection system that reduced to normal the throttle snatch by slowing down the opening of the secondary butterfly valve.
In 2010, the Yamaha FZ1 featured a revised Electronic Control Unit (ECU) mapping, improving throttle response in the low-mid rpm range. For 2011, the ECU mapping was again modified to improve throttle response at lower rpm.
The suspension system was carried over from the beginning, with a fully-adjustable telescopic fork on the front and a preload and rebound-adjustable shock absorber on the rear.
Also, the power was the same as on the 2006 model, with a 998cc four-stroke four-cylinder liquid-cooled powerplant, delivering an output power of 147 hp at 11,000 rpm and 106 Nm (77 lb-ft) torque at 8,000 rpm.
