The Yamaha FJ 1100 (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 FJ 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 FJ 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 FJ 1100 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 FJ especially for this movie.
Over the years, Yamaha makes some substantial changes (aesthetic and mechanical) to the FJ (visible in the box on the right): these updates allowed to leave the FJ 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 FJ 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 FJ, including the 20 valves per cylinder.
Today, the FJ 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.
