The Yamaha FZ 750 (also identified with the internal code 1FN) has been produced since 1985, after a bombastic presentation took place at the show in Cologne, in 1984. It boasted some very interesting technical features for the time: first, it was the first sport bike in the world to be equipped with an aluminum engine with 4 cylinders in line with 45 degrees. All this made it possible to obtain inlets straight, leaving space to the filter casing and reducing the center of gravity, thus improving the maneuverability of the vehicle (in spite of the high weight) during the phase of travel.
   The five-valve cylinder head was a feature until then described only in some theoretical mechanic manuals: Yamaha bring it to the street with exciting performance (100 hp) and the usual reliability achieved with a lot of exhaustive testing under all conditions.
   The success of FZ in terms of image is total and in 1986, Eddie Lawson won the Daytona 200 and, in the same year, 3 Italians (Norberto Naummi, Maurizio and Roberto Foppiani Ghillani) lead the FZ to win the record World Endurance, covering 30370 km with no stops in 560 hours, demonstrating the reliability of this bike.
   In Italy, part of the success of the FZ 750 is also produced because this bike was chosen to stooge for Carlo Verdone in the movie "Troppo Forte": the version used for this movie was the 1985 in the color gray/red . Even today, after more than 20 years, a lot of person remember the FZ especially for this movie.
   Over the years, Yamaha makes some substantial changes (aesthetic and mechanical) to the FZ (visible in the box on the right): these updates allowed to leave the FZ on the market until the 1993. Moreover, to keep up with the "enemy" of the time (for example, the Suzuki GSX-R 750), when it came to be put out of production, the FZ also opened the way to those that would become the modern superbikes: the Yamaha YZF-R1 (presented in 1997 and entered in production in 1998), despite an increase of cubic capacity, had similar characteristics to the FZ, including the 20 valves per cylinder.
   Today, the FZ is considered a motorcycle of historic interest and is quite searched by collectors: its quotation is 2500 euros for a model in excellent condition, while for models less cared prices range is between 1000 and 1500 euros.

It's the year in which the FZ starts to be sold to the public. It's offered in gray/red, white/red and black/red, with golden side covers.

During this year the FZ undergoes its first facelift: a tip is added to the base of the engine to improve aerodynamics, a rear handle for the passenger and the clutch is replaced with a model more powerful and less noisy. It's proposed in the colors white/red and white/blue. The golden carter are replaced with those aluminum-colored.

After 3 years, the FZ undergoes substantial changes (for this reason they change the old internal code 1FN with the new one 2KK), both aesthetically and mechanically: first of all, the engine is covered with a full fairing, the handlebars are protected by new aerodynamic devices and the side covers and the tail light have been introduced with a different design. The pistons are lighter by 25 grams each. The exhaust system changes from a classic 4 in 2 to a more engaging 4 in 1. It's proposed in the colors white/red and white/blue (but with different graphic format).

No substantive changes this year: it's proposed is in the colors white/blue/yellow (with a change of the livery).

Also this year, the FZ undergoes some major changes needed to modernize it and keep pace with competitors. The old 16" front wheel is replaced with a 17", the floating disc brakes are replaced by the same brake system mounted on FRZ 1000 (4-piston fixed calipers). The size of the tires change: from 120/80 to 120/70 to the front, from 130/80 to 140/70 to the rear.

No technical changes this year: it's proposed is in the colors gray/black and gray/white (with a change of the livery).

It's the last year in which the FZ remains in production, later replaced by modern and better performing models. Continual updates transformed the FZ, hobbling its appearance and making it less charismatic, less elegant and more squat and clumsy. No wonder that the only series to be sought by the collectors are the first two, the semi-naked models.
