Yamaha Motor Co. 5K5-84721-60-00 Brake Taillight Lens

Yamaha 5K5-84721-60-00 Brake Taillight Lens is an OEM replacement red lens for the rear tail/brake light on select Yamaha motorcycles, designed to protect the taillight bulb and diffuse the brake light output. This molded plastic, impact-resistant lens is screw-mounted to the taillight housing and serves as the outer protective cover for the rear lighting assembly, helping maintain clear signal visibility. It is specified for Yamaha XJ550, XJ650, XV750, and XV920 models from the early 1980s (typical production years 1981–1984), preserving OEM appearance and ensuring consistent light diffusion and protection of internal bulbs. Made in Japan, the lens contributes to the overall integrity of the rear lighting unit. Availability is limited because this is an OEM discontinued part; only limited NOS or aftermarket stock is typically found. Common replacements include Yamaha 4H7-84721-60-00, 3TJ-84721-60-00, and 341-84721-60-00.
