Well you didnt say what make, but Im assuming you are talking about a KTM? KTM plastic ranges are like 93-97. A couple of the years in there had white, the majority was orange. I have a 94 exc 250, let me know what you are looking for in plastics, as i have a few sets. Im not sure what the range is below a 93. But i do know the range for a 94 with plastics was 93-97.
Acerbis and UFO both still make plastics for the 93-97. They are on the pricey side though.
