The Yamaha FZR400 was a sports bike manufactured by Yamaha from 1987 to 1994 to replace the Yamaha FZ400R, which debuted only in the Japanese market in 1984. The FZR400R was updated yearly until 1994, when it was dropped from production.
The Yamaha FZR400R motorcycles were powered by 399cc naturally aspirated, carburated, four-cylinder, liquid-cooled engines mounted transversely in a perimeter-type box-section aluminum Deltabox frame, a layout quite unique for those days.
In the visual department, the bike had standard features, such as a half fairing with two round headlights up front, a windscreen for better wind protection, a two-piece dual seat, a four-into-one exhaust system with a silencer mounted on the right side, and three double-spoke aluminum wheels.
Suspension-wise, the bike packed a telescopic fork on the front and a single shock absorber on the rear, delivering optimum suspension performance and handling capabilities.
As for the stopping power, the motorcycle was fitted with two 282 mm discs with a hydraulic caliper on the front wheel and a 210 mm disc with a hydraulic caliper on the rear wheel, offering optimum braking performance.
The 1984 Yamaha FZ400R had installed a 399cc four-stroke four-cylinder liquid-cooled engine underneath its fuel tank, managed by four Mikuni carburetors, delivering 59 hp with a peak force at 12,000 rpm and 37 Nm (27 lb-ft) torque at 10,000 rpm.
