Yamaha FZR 1000

The Yamaha FZR 1000 Exup is a motorcycle that was produced by Yamaha motor in the years 1987 to 1995. The 1989er model chosen by the U.S. magazine Cycle World to the motorcycle of the decade, had an acceleration of 0-60 mph in 2.9 seconds, reaching a top speed of 267 km / h The European version of the FZR was standard throttled to 100 hp and had a top speed of about 235 km / h But various opinions, which in the 90s by various specialists (alpha technique, Bodo Schmidt, etc.) helped with the registration of the dethrottling relatively easy to carry out on nominally 107 kW/145, 5 hp ( Vmax 262 km / h ) according to the current report, which can be downloaded free of charge from Yamaha.

The 1989 built, responsible for the additional name Exup unique feature was the Yamaha patented, housed behind the exhaust valves additional exhaust control for four-stroke engines " Exhaust Ultimate Power Valve ", with the help of the back pressure of throughput joyful exhaust system speed and load dependent is varied. Thus an interpretation on a high peak power with significantly improved torque curve in the lower was made possible through the medium speed range. The engine convinced by even pulling from low revs, generated on the other hand - for those days - ample power to the rev limiter, which employs at 11800 rpm. The revving example, the air-cooled competition from Suzuki's GSX -R series never reached FZR engines, however. The Exup principle has been adapted by almost all motorcycle manufacturers, in newer models, the flap in the exhaust manifold, however, is more likely to meet stricter noise regulations become. For racing purposes, this system are often removed because the lower speed range in racing can be neglected.

The Exup system was used in the order in case the YZF 750 models, as well as from the first R1.

Model history


After introduction of super sports erfolgreichenYZF the production of the FZR models ran out quickly. This was preceded by the appearance of the groundbreaking, developed by Tadao Baba Honda CBR 900 RR Fireblade 1992. It was not until 1998 that Yamaha R1 could catch up again with the radical YZF.
