This is a genuine OEM Yamaha coolant overflow reservoir bottle designed for FZR400 sportbike models. Made from semi-translucent High-Density Polyethylene (HDPE) plastic, this tank allows quick visual coolant-level checks. It stores excess coolant as engine temperature rises and returns it to the radiator as the cooling system cools. The reservoir features an elongated factory shape, integrated upper mounting eyelets, a lower fluid outlet nozzle, and a black press-fit cap. It is suitable for factory restoration, maintenance, or replacement applications. Compatible Models & Years * Yamaha FZR400R (3EN1 / 3EN2) — 1988–1989 * Yamaha FZR400RR (3TJ1 / 3TJ2 / 3TJ6) — 1990–1994 * Yamaha FZR400RR SP (3TJ4 / 3TJ7) — 1990–1994 Please compare the frame prefix and mounting layout before purchase, as some 1987 1WG models may use a different bracket configuration.
