Yamaha FZ 750 (1989-1991)

The Yamaha FZ 750 Genesis was first introduced in 1985 and at the time had all of Yamaha's advanced technology.

The motorcycle competed well with all sports bikes of those years and was quite popular. This was due to the use of innovative technologies, such as - the forward-tilted 4-cylinder Genesis engine with a lowered center of gravity, which increased the handling of the motorcycle; the generator behind the block of cylinders (and not at the end of the crankshaft as on competitors), which made the motorcycle much narrower than competitors; Outstanding speed performance - the maximum claimed speed was about 150 mph (~ 241 km / h), which at that time was a very impressive result.

The Yamaha FZ750 Genesis was based on an in-line 4-cylinder liquid-cooled engine with a volume of 749 cc. see, issuing from 100 to 110 hp. power (depending on the region of sale) and 80-81 Nm of torque. Maximum performance - at 8000-10000 rpm.

The frame of the motorcycle is tubular steel. The suspensions are simple, in the front there is a usual 39 mm telescopic fork, in the back there is a mono-shock absorber with a progression, adjustable in preload. The braking system of the Yamaha FZ750 changed depending on the year of manufacture - the most powerful brakes were on the motorcycle, since 1989 - 2 discs of 298 mm with 4-piston calipers. The total curb weight is 229-232 kg (depending on the year of manufacture). Fuel tank - 21-22 liters (depending on the year of manufacture).

The Yamaha FZ750 Genesis model existed on the market until 1991 (inclusive), after which it was discontinued. The Yamaha FZ750 Genesis and Yamaha FZR750 Genesis left the market and were replaced in 1993 by the sports model Yamaha YZF750. Despite the fact that the Yamaha FZ750 was focused mainly on export to Europe and North America, there are currently a number of models presented at Japanese auctions.
