# Service bulletins for the 2021 Kawasaki Z400

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

2 bulletins from NHTSA, as of 2026-10-19.

- [MC24\-01](/bulletins/10249813.md), 2024-02-07, Service bulletin: STRUCTURE. Service Information about a shipping bracket attaching the motorcycle to the crate can cause damage to the motorcycle fuel tank if removed.
