How to Install Quick-Release Sissy Bars on Harley Sportster Motorcycles

All quick-release Harley Sportster sissy bars come with a quick-release latch that slide over the docking points. Harley Sportster quick-release sissy bars feature a four-point docking system and a latch-lock system. Installing a quick-release Harley Sporster sissy bar usually takes less than 15 minutes.

Tools Required

Tools Required

  • ½-Inch Wrench
  • Torx Bit - Preferably T40
  • Torque Measuring Tool - A Dial Wrench or A Digital Torque Wrench
  • Loctite Threadlocker
  • Hex-Head Screwdriver
  • Included Docking Hardware

Installation Steps

  1. Use a wrench or a T40 Torx bit to remove the old front bolts on the rear fender strut before inserting the front docking hardware. Hold the nuts along the rear fender while unfastening the bolts.
  2. The new front docking hardware is smaller and has a ridge that goes inside the docking point. Slide the front bolt through the docking hardware and apply loctite threadlocker to the bolt.
  3. As you position the new front docking hardware, insert the front bolt and fasten the nut behind the fender. If you have difficulty fastening the nut, use a jack to lift your Harley Sportster to create enough space to hold the nut in place and torque the bolt from the front.
  4. To verify whether the bolt is fastened to a specific level of torque, use a torque measuring tool. At high speeds, sissy bars can be subjected to heavy vibrations that might loosen the bolts.

However, applying to much torque to a bolt can damage the threaded bolts and fasteners. To measure torque accurately, use a dial wrench or a digital torque wrench.

  1. With the front docking hardware in place, remove the rear bolts using a wrench.
  2. This step is optional. But if you want to protect the turn signal lenses, you can remove the turn signal cap before unfastening the second bolt behind the turn signals. If you prefer leaving the turn signal caps on, use a wrench with a Torx bit attacked to carefully remove the rear bolt.
  3. The rear docking hardware is larger and features a small ridge that fits into the docking hole. Slide the bolt through the docking hardware and apply loctite onto the bolt. Fasten the bolts to prepare the docking base for the Harley Sportster quick-release sissy bars.
  4. Slide the quick-release sissy bars on the front docking points and then on the back. Press the back of the sissy bar lightly into place until you hear a click.

3.1 Installing Quick-Release Sissy Bars with Luggage Racks

If you plan to install quick-release Harley Sportster sissy bars with luggage racks, there are additional steps you must follow:

  1. Remove the top bolt on the rear fender before installing the rear docking points on the fender support.
  2. As Harley Davidson Sportster motorcycles lack a passenger seat, the top bolt on the rear fender can be used to secure a pillion/passenger seat. However, if you install the luggage rack without a passenger seat, you would use the same bolt to mount the luggage rack on the fender.
  3. After removing the top bolt using a hex-head screwdriver, insert a large contoured washer between the fender bracket and fender.
  4. Unfasten the two rear bolts on the fender strut to loosen the rear fender.
  5. Slide your hand in between the rear tire and the fender as you secure the contoured washer in place.
  6. After fastening the washer, put the top bolt removed earlier from the fender back temporarily to hold the washer and fender bracket in place.
  7. Hold the luggage rack against the rear holes on the side of the fender struts and install the docking hardware to affix the luggage rack. Slowly fit the luggage rack to prevent paint from chipping or causing other damage to the fender.
  8. Remove the top bolt fitted earlier on the fender holding the contoured washer and bracket in place.
  9. Put a nylon or rubber washer on top of the fender above the hole. Then place a steel washer on the top of the fender top and place a small spacer over that.
  10. Lastly, place a medium-sized washer larger than the spacer and align the luggage rack with the holes on the fender before bolting it in place.
  11. After installing the luggage rack, slide the quick-release sissy bars on the rear docking points next to turn signals on the fender struts and lock the latch system.
