Year & Model Identification

Harley Davidson Aermacchi Motorcycles 1961 to 1969

From 1961, the first year for the Sprints, to 1969, the code was as follows:

First, there are two digits for the year, then a letter for the model, followed by 5 numbers for that production cycle.

EXAMPLE:

1962 250 H

62H14556

  • The Sprint models for those years were C, H & SS.
  • The M series were M for the step-thru and for the sport either M or MS.
  • The 125 Rapido was ML for 1968 and early 1969 street models.
  • MLS is for the Enduros.

However between 1967 and 1969, the factory did not always stamp the year, so here is what to look for:

  • The 1967 and 1968 250 have a round slide UB24 cable, with a single exhaust.
  • The 1969 SS 350 have a square VHB27 cable and dual exhausts.
  • On the 250 motors the ID number is in the front under the oil return tube. The 350 have their number on the left at the front.
  • For the M series, the number on the right, just below the cylinder.
  • The Rapido number is found on the right, but at the back of the motor.
  • Sprint frame numbers are on the right side of the neck, on a vertical plate.
  • On the small two strokes, the numbers are on a plate by the side stand and swing-arm.
  • The larger and later two strokes are stamped on the neck.
