About the Yamaha FZR400
Fork, brake and engine repair parts for an FZR400 restoration.
Yamaha introduced the production FZR400 in 1986 with the Genesis concept, a liquid-cooled inline-four engine and an aluminum Deltabox frame. For a restoration today, its full model and engine identification matter as much as the FZR400 name. Retain any R, RR or S suffix and note replacement forks, brakes or engines before selecting their service parts.
Pay attention to the 1989–1990 parts boundary
The linked fork oil seals list FZR400 1988–1990, while the dust seals and clutch plate have 1988–1989 FZR400 applications. The rear master-cylinder kit separately lists FZR400 and FZR400R 1986–1990. For engine work, compare the gasket set with the exact engine variant and the joints being opened. The linked exhaust gasket is sold individually, so check the joint and quantity needed.
Know your model before choosing partsFZR400 repair checkpoints
Fork seals
Oil seals through 1990; dust seals through 1989
The linked oil seals measure 38 × 50 × 8/9.5 mm. The separate dust-seal listing does not establish 1990 fitment.
Clutch parts
FZR400/FZR400S: 1988–1989 clutch plate
The linked clutch plate lists these models and years. Check plate type and quantity; FZR400R and FZR400RR require their own verified applications.
Engine and exhaust
Confirm contents and quantities
The engine gasket set lists FZR400 1988–1994. The linked exhaust gasket lists 1988–1990 and is sold individually; verify the exact engine and joint being serviced.
