How to Install Hard Mount Saddlebags on a Harley Softail: A First-Timer's Guide

Hard mount saddlebags look right, stay put and feel solid at speed. They also make a lot of first-time installers nervous, because drilling is part of the job and a misplaced hole cannot be undone. If you are staring at a box of bags and a drill and wondering how bad it will be, you are in good company.

This guide draws on a customer's video of installing our Legacy extra large studded leather saddlebags on his 2021 Harley-Davidson Heritage Classic, and on the fitment and installation details on our product pages. It explains what hard mount really means, how to prepare, what a realistic first install looks like, and how to avoid the mistakes that cost time. If you want a closer look at the bags themselves rather than the install, see our review of the best-looking Harley Heritage Classic leather saddlebags.

• What does hard mount mean? The bags attach to the bike with fixed brackets and hardware. Viking describes this as a secure, stable and fixed setup, as opposed to quick-mount bags that come off in seconds.
• Do hard mount saddlebags need drilling? It depends on the bag and the bike. The customer who installed the Legacy bags on his Heritage Classic said drilling was part of the process, so read the manual for your model before you start.
• How long does the install take? Viking rates the Legacy bags for Heritage Classic as a medium install. The customer, working alone for the first time, spread it over two days.
• Do I need to move my turn signals? On the Legacy bags for the 2018-and-newer Heritage Classic, no. The listing says turn signal relocation is not required, and the bags have cutouts for the signals.
• Is hardware included? Yes. The listing says the hard mount hardware is included free.

Saddlebag mounting comes in two broad styles, and the one you choose changes how the install goes.

• Hard mount: The bag is bolted to brackets or mounting points on the bike. Viking's listings describe it as a secure, stable and fixed setup. It will not rattle loose or shift, but you do not take the bags on and off in seconds.
• Quick mount (quick disconnect): The bag clips onto a docking system and, according to Viking's listings, installs and removes in seconds.

You will find hard mount, quick-mount and throw-over styles for most major brands on our motorcycle saddlebags page, which also lets you shop by bike.

Viking also labels each listing with an installation level of easy, medium or hard. In the listings we reviewed, quick-mount bags were rated easy, many hard-mount bags were rated medium, and a few hard-mount setups were rated hard. The rating is a guide, not a promise, because your skill and tools matter as much as the bag.

Most installation problems begin with a fitment mistake, so confirm these before you open the box:

1. Exact model and year. The Legacy bags in this guide fit the Softail Heritage Classic FLHC/S from 2018 to current. If you ride an older Heritage, Viking lists separate bags for the FLSTC/I, so browse the Heritage FLSTC/I saddlebags instead.
2. Turn signal note. Check the fitment note for "Turn Signal Relocation Required."
3. Mounting type. Confirm whether the listing says hard mount or quick mount.
4. Hardware. Viking states that required hardware is included unless noted otherwise.
5. The manual. Read the instructions supplied with your bags before you drill anything.

You can see every option for this model on our Harley Softail Heritage FLHC/S saddlebags page.

Large saddlebags can sit where a Softail's rear turn signals are mounted. Manufacturers solve it in one of two ways:

• Cutouts: The bag is shaped with openings so the stock signals stay in place. This is the case for the Legacy bags on the Heritage Classic, which means the install does not include moving the signals.
• Relocation: The signals move to a new position, often near the license plate, using a relocation kit. Viking's fitment notes tell you when this is required, and some listings include the kit.

Cutouts keep the job simpler, which is one reason the Legacy bags suit a first-timer better than a setup that also needs the turn signals moved.

The customer in the video was candid, and his experience is a useful reality check. He describes himself as still learning, and his install looked like this:

Three lessons stand out. Slow, careful planning pays off. An aftermarket exhaust adds a clearance check. And the second bag is always easier than the first.

These are general good-practice steps. Always follow the instructions that come with your bags, because hole locations, bit sizes and fastener details differ by model.

1. Read the manual and gather your tools. Typical needs include a drill and bits, a marker, wrenches or sockets, and masking tape. Check the manual for the exact list.
2. Lay everything out. Identify each part and confirm nothing is missing before you start.
3. Dry-fit before drilling. Hold the bag in position and check it against the bike, the fender and the exhaust.
4. Compare both sides. Make sure the left and right bags will sit symmetrically.
5. Mark, then check again. Mark hole locations as shown in the manual, step back and compare before you drill.
6. Check exhaust and tire clearance. If you run an aftermarket exhaust, allow extra time for this step.
7. Drill carefully. Go slowly and follow the manual's guidance.
8. Mount and tighten. Fit the bag, then tighten the fasteners as the manual directs.
9. Repeat on the second side. Use what you learned on the first.
10. Recheck after your first ride. Hardware can settle, so check that nothing has loosened.

• Rushing the layout. Misplaced holes are the most common regret.
• Working alone without support. A second person makes positioning much easier.
• Skipping the exhaust check. Heat and contact can damage a leather bag.
• Not asking for help. If you drill a hole in the wrong place, contact the manufacturer before sealing it. The customer planned to use silicone, but a manufacturer can tell you whether that is appropriate for your bag.

The customer's test ride is a good model. After mounting, he wanted to see whether the bags felt stable, and he rode to check for shifting, movement, clearance problems, rubbing or bouncing. In his case, the bags performed well with no issues.

Use the same checklist on your first ride:

• Stability: Do the bags shift or rock?
• Clearance: Does anything touch the exhaust, tire or shock?
• Noise: Do you hear rattling or rubbing?
• Closures: Do the lids latch the way you expect?

That last point caught the owner out. The front snap flap kept coming loose until he realized there is a twist closure, and he said that one might be on him. If a closure seems not to hold, check the instructions or look for a twist feature before assuming something is wrong.

The Legacy bags are structured and reinforced, and the listing describes a metal frame with a plastic-reinforced lid and body. They offer 35 liters across the pair, which Viking lists as holding about 49 cans, and the listing gives the dimensions as 23 by 7 by 14 inches (length by width by height) with a 13.25 by 6.25 inch lid opening. They are key lockable, and the customer mentions two keys are included. As with any lock, treat it as a deterrent and take valuables with you.

To get the most out of the space, our guide to packing saddlebags for better weight distribution shows how to load them evenly.

If the idea of drilling worries you, Viking lists several quick-mount options for the same bike. You can compare them on the Heritage FLHC/S luggage by bike page. If you want the studded leather look and a fixed setup, the Viking Legacy extra large studded leather saddlebags are the model the customer installed.

A first-time installer can manage a medium job with patience, as the customer showed, but it helps to be honest about your comfort with drilling and your tools. Consider a shop if you are unsure about hole placement, cannot get a helper, or have an unusual setup such as an aftermarket exhaust that affects clearance. You can also contact the Viking team with questions before you start, and the listings invite you to ask about installation.

Hard mount saddlebags reward a little patience. Plan the layout, check your fitment note, follow the manual, take your time on the exhaust side, and let the second bag teach you what the first one could not. If you want the fixed, finished look of a bag that does not move, the effort is worth it. If you would rather skip the drilling, there are quick-mount options for the same bike. Either way, our motorcycle saddlebags page is the quickest way to compare styles by bike, and our Harley saddlebags range covers the Harley-specific options.
