• 1986-1991 Sportster Top Center Mounts:
  • Made for right side petcock.
  • 86-91 top center mounts are identical except for the finish.
    883 center mounts had a natural metal finish and 1100/1200s were black powder coat.
  • Both have a 3/8“ vertical hole near the left center end of the base plate to bolt the key switch cover (under) the motor mount.
    883 had a 3/8” bolt for the key switch cover and 1100 / 1200 had a stud thru a horn bracket mounting the horn and switch cover to the motor mount.
  • Both have a 1/4“ hole through the back plate to bolt the VOES to the rear side of the mount.
  • Both have a slotted hole through both the “ears” that mount to each head for adjustment.
  • There is minimal welding on the back of the side plates that attach to the base of the mount.
• 1992-1993 Sportster Top Center Mount:

• 1994 Sportster Top Center Mount:
  • Made for right side petcock.
  • The 94 mount looks identical to the 92-93 mount on face value.
    The only notable difference seems to be in construction changes.
    The stud for mounting the VOES has an indention in the head as if welded there.
    The 3/8“ hole in the left center seems to be moved further toward the outside edge (or maybe the edge was cut slightly shorter by the factory).
  • Has the 3/8” hole on the center left of the base plate (no longer used for the key switch) for the horn bracket (1200).
  • Has the 2nd hole (1/4“) in the middle of the base plate for mounting the key switch cover on (top) of the motor mount.

    The key switch would interfere with the left side petcock so the switch was moved to the right side of the bike with a different cover.

    A bolt or threaded rubber bumper now bolts thru the slot to mount the horn.

  • It has a full weld on the inside of the side plates that attach to the base of the mount.
• 1997 Sportster Top Center Mount:
  • Made for left side petcock.
  • The 97 center mount looks identical to the 95-96 mount but the big hole thru the center of the base was cut different on the left side.
    The “wings” or side ends at the base plate are also longer giving more strength to the assembly.
  • Does not support a key switch.
  • The left center edge was bent down differently still having a vertical slot in the center (slot faces up, hole faces out).

  • Enrichment cable ready.
    The 98-03 center mount is identical to the 97 mount with exception of an enrichment cable bracket built into it.
    88-97 center mounts use an additional bracket onto the center mount to attach the enrichment cable.
  • The left center edge is bent just like the 97 mount still having a vertical slot in the center (slot faces up, hole faces out).
    A bolt or threaded rubber bumper bolts thru the slot to mount the horn.
  • The metal extends from the horn bracket slot forward to another slot for the enrichment cable (slot faces down, hole faces out).
  • Does not support a key switch.
  • Has a 1/4“ hole through the back plate to bolt the VOES to the rear side of the mount.
