Engineered by Yamaha for the sport motorcycle segment, the 1989 Yamaha FZR 400 pairs a 399 cc (24.4 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 56.0 x 40.5 mm (2.2 x 1.6 inches) with a 11.5:1 compression ratio.
On the scales, the FZR 400 measures 172.8 kg (381 lbs) dry. Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 18.16-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
