Who says there is no parts interchangeability between models these days. Reflector on left is off my 40 year old Kawasaki KV100, on right is off my 2019 Kawasaki Z900RS. Same Stanley part number on rear, front reflector is same but for colour letter. Seems the difference may be that it is no longer made in Japan ( deleted on back). Probably now produced in China for 50c but Kawasaki spare parts want $20 U.S. There must have been millions of these things put on loads of Japanese bikes. Kiffsta probably has a bin load! Interestingly, upon checking, I found that ADRs require that a front side reflector be yellow or white while a rear side reflector be red. This is how they are placed on the KV and the Z-RS. If you have both front and rear, they must be the same height above the ground. What seat-warmers sit and make these rules?
