I bought an old KHS aerosport used a few weeks ago and i’m curious about when it was made. I searched every bike encyclopedia and couldn’t find any evidence of one made before 1993, but mine has a sticker saying it was registered in honolulu before 1990 so i’m very curious. Any information would be greatly appreciated. I’m not allowed to upload an image because it’s my first post but it’s two toned pale green and purple with 80s-esque yellow lettering.
