I think the OEM bars on the early '86's were either Kusuki Winpista or Nitto B115. I think the Nittos came in with the '87s, as Loose Chain says above.

They were definitely Japanese. A.Winthrop still has an '86, so he'll enlighten us. I'm working from memory here.

Bar tape would not be fade. Black or white only, as far as I know.
