• Differences between 1985-1986 frames:
  • Different engines designs:
    • 1985 was the last year of the Ironhead engine. 1986 was the first year of the Evo engine.
  • Motor Mounts:
    • The top front mount on 1985 was removable/adjustable. Top front mount on 1986-up engines is in a fixed position.
    • The top center mount was redesigned in 1986. 1986-2003 top center mount brackets will all interchange (if only speaking of mounting to the heads and frame).
      However, considerations will have to be made for the ignition switch, fuel tank petcock and possible horn locations depending on the year model of your motorcycle.
