The Harley-Davidson Dyna Switchback FLD is a unique model in the Dyna lineup. It is the only one designed to switch between a stripped-down naked bike and a light touring setup. The detachable windshield and, most importantly, the saddlebag mounting system are what give it this flexibility.
Because of this design, fitting saddlebags on the FLD is a bit more involved than on most other Harley models. The Switchback uses a specific conversion bracket system that is different from standard Dyna mounting setups. When the correct bracket system is used, the bags sit neatly and stay secure. However, if the setup is incorrect, the saddlebags can rattle, sit unevenly, or even interfere with the exhaust.
Here is everything you need to know before buying. The complete Harley-Davidson Dyna Switchback FLD Saddlebag 2012-2016 is available at Aliwheels.
What Makes the FLD Saddlebag Different?
Standard Dyna models use a simpler mounting system that attaches to the rear fender struts or frame tabs. The Switchback FLD uses a conversion bracket kit because the FLD frame and rear-end configuration require a different attachment approach to achieve the clean integration Harley-Davidson designed into the bike.
The conversion brackets in a properly engineered FLD saddlebag kit serve three functions simultaneously. They provide the correct standoff distance to prevent bag contact with the rear wheel and exhaust system. They establish the correct bag angle relative to the bike’s rear end geometry. And they create a stable mounting base that prevents bag movement under load and vibration.
A bag kit supplied without FLD-specific conversion brackets, or with universal brackets not designed for the FLD frame configuration, will require modification to fit correctly or will produce an insecure or visually incorrect installation.
What Is Included in the FLD Saddlebag Kit?
The Harley-Davidson Dyna Switchback FLD Saddlebag with Conversion Brackets includes a pair of saddlebags in vivid black ABS plastic construction, left and right conversion mount bracket kits in iron and rubber construction, and speaker lid provisions sized for 6 x 9 inch speakers for riders wanting audio integration.
The ABS plastic construction matches the material used in Harley-Davidson’s OEM bag components. The iron and rubber bracket construction provides the rigidity needed for secure mounting with rubber isolation to reduce vibration transmission to the bag body.
Exhaust Clearance: The Most Important Fitment Check
Before finalizing any saddlebag installation on the Dyna Switchback FLD, exhaust clearance on the right side is the most critical point to verify. On the FLD, the exhaust runs close to the right saddlebag mounting area, so spacing becomes a key safety and durability factor.
If there is not enough clearance between the bag and the exhaust, two problems can occur.
First, heat damage to the saddlebag material. Constant radiant heat from the exhaust gradually weakens ABS plastic. It often starts with discoloration, then surface softening, and eventually can lead to deformation in the area closest to the exhaust.
Second, there is a fire risk. ABS plastic can ignite at lower temperatures than many riders expect. If a bag sits too close to a hot exhaust header, it becomes a serious safety concern.
Correct FLD conversion brackets are designed to create the proper spacing and prevent these issues. During installation, always check that there is at least 50 mm of clearance at the closest point between the right saddlebag and the exhaust, measured with the bag fully loaded to its intended maximum weight.
Harley-Davidson Dyna Switchback FLD Saddlebag Installation Guide: Step by Step
The saddlebag installation on the FLD Switchback using conversion brackets is typically a two- to three-hour job for someone working on a home workbench for the first time.
Step 1: Gather the correct tools
You will need a metric socket set, a torque wrench, medium-strength thread locker, and the FLD service manual for correct torque values.
Step 2: Install the conversion brackets first
Fit the brackets to the frame mounting points before attaching the saddlebags. Make sure each bracket is oriented correctly, as the left and right sides are not interchangeable. Apply thread locker and torque all mounting bolts to specification.
Step 3: Test-fit the saddlebags
Mount each bag onto its bracket before fully tightening everything. Check that each bag sits level, clears the exhaust on the right side, and does not contact the rear wheel or fender on either side.
Step 4: Check suspension travel clearance
Move the rear suspension through its full range by hand. This is important because clearance at rest does not always guarantee clearance under load or full compression. Watch closely for any contact points.
Step 5: Final tighten all hardware
Once alignment and clearance are confirmed, tighten all fasteners to the correct specification. Double-check every mounting point for security before riding.
Step 6: Post-installation check after riding
After the first 50 miles, re-check all mounting hardware. It is normal for newly installed parts to settle slightly under vibration, and a quick re-torque check helps ensure long-term stability.
Speaker Lid Option: What to Know
The 6 x 9 inch speaker lid provision in the FLD saddlebag kit allows audio integration for riders who want music while touring. If you plan to use this feature, ensure the speaker selection fits a 6 x 9 standard mounting pattern and has a depth that fits within the lid recess without contacting the bag interior.
Sealed speaker units resist moisture better than open-back designs in an outdoor saddlebag environment. Route any audio wiring through the bike’s fairing or frame tubes rather than leaving it exposed to the elements.

Conclusion
The Harley-Davidson Dyna Switchback FLD saddlebag installation is a rewarding upgrade that significantly improves the bike’s touring ability. The conversion bracket system is the most important part of the setup, since without it the saddlebags will not align properly with the FLD’s specific frame and rear-end design.
Exhaust clearance on the right side must be checked carefully. Even small misalignment can lead to heat damage or unsafe proximity to the exhaust.
Use medium-strength threadlocker on all mounting hardware, and tighten everything to the correct torque specifications. After the first 50 miles, recheck all fasteners to ensure nothing has loosened during initial use.
When installed correctly, the saddlebags integrate cleanly with the FLD’s dual-purpose design and provide practical storage for weekend touring without affecting the bike’s stability or look.
Frequently Asked Questions
Q: Will standard Dyna saddlebags fit the Switchback FLD without the conversion brackets?
A: Standard Dyna saddlebag mounting hardware is not directly compatible with the FLD’s frame configuration. The Switchback FLD requires the specific conversion bracket kit to mount bags correctly. Attempting to fit standard Dyna bags without FLD-specific brackets either requires modification or produces an insecure installation that risks bag movement at speed.
Q: What is the weight capacity of the FLD saddlebags?
A: Each saddlebag in a correctly installed kit is rated for 15 to 20 lbs of contents under normal riding conditions. Do not exceed this limit as overloading affects the bike’s handling through rear weight bias and increases stress on the mounting bracket system. Distribute heavy items between both bags equally to maintain side-to-side balance.
Q: My FLD saddlebag is rattling after installation. How do I fix this?
A: Bag rattle on the FLD is almost always caused by loose mounting hardware, insufficient thread locker on fasteners, or contact between the bag and a hard surface on the bike. Re-check all mounting bolts for correct torque. Check that the bag does not contact the fender, exhaust heat shield, or any other hard surface during normal riding. A rubber isolation shim at any identified contact point eliminates metallic rattling.
Q: Can I lock the FLD saddlebags?
A: The ABS plastic FLD saddlebag kit from Aliwheels uses a standard latch closure. For riders requiring lockable security on parked bikes, aftermarket lock barrel upgrades compatible with ABS saddlebag latches are available separately. Alternatively, a small luggage lock through the latch provides deterrent security without structural modification.
Q: Are the FLD saddlebags waterproof?
A: ABS plastic saddlebags provide good water resistance for normal rain conditions. The latch area and any gaps at the lid seal are potential water ingress points in heavy sustained rain. For fully waterproof storage, use waterproof dry bags or liner bags inside the saddlebags to protect electronics and clothing in heavy precipitation.
