About the Kawasaki ZX750H Ninja ZX-7 / ZXR750
1989–1990 H-model service parts for the early Ninja ZX-7 and ZXR750.
The ZX750H is the early Ninja ZX-7 branch also known as ZXR750 across markets. Its 1989 H1 uses liquid cooling, including a radiator, water pump, thermostat and hoses. For engine work, note which engine joints and cooling-system connections will be disturbed so the repair order covers the actual seals needed.
Plan the fork service as two separate seal purchases
The linked fork oil seals come as a set of two, while the dust seals are sold individually. Both cover ZX750H 1989–1990. Carburetor rebuild kits, engine gaskets and front brake pads also have H-model options for those years. Keep the H code in the search to avoid mixing them with later M-model ZX-7R parts.
