Yamaha FZR 1000

FZR 1000 Genesis

The FZR 1000 (from 1989 with the additional designation EXUP ) is a motorcycle that was produced by Yamaha Motor from 1987 to 1995. The vehicle, which was offered in several model variants from 1988 to 1994, has a liquid-cooled four-cylinder in-line engine with five-valve technology and a displacement of 989, from model 1989 onwards of 1003 cm³. In 1995 the FZR was replaced by the Yamaha YZF 1000 Thunderace. Currently 297 FZR (models '87 / '88) and 994 EXUP models (models 1989–1994) are still registered in Germany, as of January 1, 2019.

The 1989 model, named Motorcycle of the Decade by US magazine Cycle World , accelerated from 0 to 60 mph in 2.9 s and reached a top speed of 267 km / h. The European version of the FZR was throttled to 100 hp as standard and had a top speed of about 235 km / h. Various reports that were made by various specialists in the 1990s (alpha-Technik, Bodo Schmidt etc.) helped with the entry of the relatively easy dethrottling to a nominal 107  kW (145.5  PS ) (top speed: 262 km / h) according to .current certificate that can be downloaded free of charge from Yamaha.

Exup system

The unique selling point responsible for the Exup addition to the name , which was installed from 1989 onwards , was the additional exhaust control system for four-stroke engines, " Exhaust Ultimate Power Valve ", patented by Yamaha and located behind the exhaust valves , with the help of which the back pressure of the exhaust system is varied depending on speed and load. This made it possible to design for high peak performance with a significantly improved torque curve in the lower to medium speed range. The engine impressed with its steady torque from low speeds, on the other hand - for the conditions at the time - it generated a full power up to the speed limiter, which kicks in at 11,800 rpm. FZR engines, on the other hand, never achieved the high revving speed of the air-cooled competition from Suzuki's GSX-R series. The Exup principle has been adapted by almost all motorcycle manufacturers, but in current models the flap in the exhaust manifold is more likely to meet stricter noise regulations. These systems are often removed for racing purposes, as the lower speed range can be neglected in racing.

The Exup system was subsequently also used in the YZF 750 models, as well as from the first YZF-R 1 .

review

After the successful YZF super sports car was launched, production of the FZR models quickly came to an end. This was preceded by the appearance of the groundbreaking Honda CBR900RR Fireblade developed by Tadao Baba in 1992. It took until 1998 for Yamaha to catch up with the radical YZF-R 1 .
