The Yamaha FZR400R Genesis was a in-line four, four-stroke Sport touring motorcycle produced by Yamaha between 1984 and 1993. Max torque was 30.98 ft/lbs (42.0 Nm) @ 9500 RPM. Claimed horsepower was 55.12 HP (41.1 KW) @ 12000 RPM. It could reach a top speed of 197.5 km/h.

Overview[edit]

The FZR 400 has the good reputation of being one of the best handling motorcycles ever produced. In the US this bike was imported only for three years, between 1987-1991. The Yamaha FZR400’s liquid-cooled, four-cylinder, 16v DOHC engine revs to an impressive 14,000rpm, but like most other four cylinder 400s nothing really happens below 5000rpm. In terms of outright performance, the Yamaha’s back wheel 64 hp was slightly down compared to the competition, but on a positive note it did make the FZR usable.

For a very long time, the Japanese home market has envied the big supersports models destined, principally, for the USA and Europe. Now the trend is being reversed, for the 400cc machines developed for Japan have become such high performers that the rest of the world dreams of profiting by them. Now prayers are being answered, and among the outstanding new models reaching other shores is the Yamaha FZR 400R .


The Yamaha FZR400 was always over-shadowed by the class-leading Hondas, both the CBR and V4 NC30 and NC35s, and, on track, was a little behind Kawasaki's ZXR400 for sheer speed. However, the rev-happy Yamaha FZR400RR attracted the hooligans by the bucket load, drawn to the high-revving engine, sharp handling and high corner speed. And, as it was also always considerably cheaper than the competition, it meant that many ended up on track as race bikes or fun track day machines.

In terms of outright performance, the Yamaha's back wheel 64bhp was slightly down compared to the competition, but on a positive note it did make the FZR usable.

The reason why so many Yamaha FZR400's ended up on track was due to the excellent handling and ease of use. There's no "getting-to-know-you" period, you can just jump on and attack any section of road. It's lightweight, flickable, will carry huge lean angles and you don't need to be an expert to have fun, the FZR400 really flatters its rider.

Exclusive and Uncompromising[edit]

Crowned with success in Japan, the FZR400R is an exclusive and uncompromising sports machine that has nothing to be ashamed of in comparison with the largest-capacity bikes, with which it shares all the latest advanced technology

Sensational Power/Weight Ratio[edit]

The four-cylinder engine is suspended below two aluminum box girders as on contemporary Grand Prix machines The inclined cylinders, which allow the use of straight-line intake tracts, the 16-valve head, and the EXUP system of a valve in the exhaust, give the machine a fierce temperament allied to great flexibility and an astonishing power output equivalent to 152 hp per liter. Lively and agile, the FZR400R draws full profit from its sensational power/weight ratio. Its riders discover that a highly tuned machine of moderate displacement is more efficient, in most cases, than a "big hanger," which needs a very particular environment to give its best.

Engine[edit]

The engine was a air cooled in-line four, four-stroke. A 56.0mm bore x 40.0mm stroke result in a displacement of just 400.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).

Drive[edit]

The bike has a 6-speed transmission. Power was moderated via the Wet multi-plate.

Chassis[edit]

It came with a 110/70-r17 front tire and a 140/60-r18 rear tire. Stopping was achieved via double disc in the front and a single disc in the rear. The front suspension was a telescopic while the rear was equipped with a monocross. The FZR400R Genesis was fitted with a 4.76 Gallon (18.00 Liters) fuel tank. The bike weighed just 380.96 pounds (172.8 Kg).
