The Yamaha FZ1 is a street motorcycle manufactured by Yamaha in Japan. The 600 cc FZ6 and 800 cc FZ8 are related.

 

Generation I (2001–2005)

Yamaha FZS 1000S Fazer (2002)

Generation 1 models are known as FZ1 in the United States and FZS1000 Fazer in Europe. They have tubular steel frames and modified Yamaha YZF-R1 engines which are carbureted. The models were virtually unchanged over this period, except for colour options, the introduction of the FZS1000S which had a black engine, and in some European countries the 2005 models were fitted with rudimentary catalytic converters.

 

Generation II (2006-2015)

2006 saw the introduction of a completely new model. The main changes included a new chassis, suspension, body work and a completely new engine, never seen before in the big Fazer. Cast aluminum die-cast diamond-shaped frame with the engine as stressed member replaced the older tubular steel frame along with a control-filled die-cast swingarm. This brought the bike up to date with modern rivals. The new model has a 998 cc DOHC 20-valve engine from the 2004–2006 R1 tuned for better midrange torque, set in an all-new compact diamond-shaped aluminium frame. Most of this engine is identical to the sister YZF-R1's. The primary internal changes are a 40 percent heavier crankshaft and revised balance shaft. New camshafts with reduced lift and duration aim to boost performance at lower revs, and the gearbox's top two ratios are higher to give a more relaxed feel at cruising speeds. Modifications are as follows:

2006

• Stiff rear spring with a 700 lb/in

• 2006 version when first introduced had distinct throttle snatch at 5000–6000 rpm, where rolling off the throttle and rolling back on caused a distinct surge in acceleration due to faster opening of the sub-throttle plates or secondary butterflies.

2007

• Softened rear shock spring.

• Fuel Injection updated. Throttle snatch resolved by slowing secondary butterfly opening.

2010

Revised ECU mapping to achieve improved throttle response in the low to mid rpm range.

2011

• The ECU mapping revised for improved throttle response at low rpm.
