This is an OEM Honda Rear Inner Fender, also known as a rear splash guard, undertail tray, or mudguard. Made from factory-grade ABS plastic, it protects the under-seat electronics, battery box, rear suspension, and wiring from mud, water, and road debris thrown by the rear tire. It includes factory alignment tabs, wiring-harness mounting points, and molded recesses for direct installation on the original subframe. Compatibility Guide 100% Direct Fit Honda CB-1 400 / CB400F — 1989, 1990 Honda CB-1 400 NC27 — Models using the original NC27 subframe and NC23-derived engine platform Fitment Note Some 1991–1992 JDM or European-market models may fit only when equipped with the unchanged NC27 subframe. Not compatible with later Honda CB400 Super Four / NC31 models because they use a redesigned frame, rear suspension, and tail assembly.
