The FZ1 was a naked machine that debuted in 2001, known as the FZ1 in the United States and FZAS1000 Fazed in the European market. The bike was manufactured over two generations, the first from 2001 to 2005 and the second from 2006 to 2015.
The first generation motorcycles were built on a tubular steel frame that housed a modified version of the engine used in the YZF-R1, fed by carburetors. From 2001 to 2005, the models were virtually unchanged, except for color options. Also, The 2005 FZS1000S, released in 2005, packed a blacked-out engine, while in various countries was fitted with catalytic converters.
The second generation machines came in a completely different package, with many technical and visual modifications, including a new chassis, suspension, bodywork, and YZF-R1-derived engine tuned for better mid-range torque.
In 2009, the Japanese manufacturer released the Yamaha FZ1, a semi-naked motorcycle that packed a front cowl with a dual-headlight system and small windscreen for enhanced wind protection, a two-piece dual seat with passenger grab handles, a black-out engine and frame, and five-spoke wheels.
In the performance department, the 2009 Yamaha FZ1 boasted 147 hp at 11,000 rpm and 106 Nm (77 lb-ft) of torque at 8,000 rpm. The 998cc four-cylinder liquid-cooled engine was paired with a six-speed manual transmission and a final chain drive, launching the bike to 247 kph (153 mph).
