The Harley-Davidson Dyna is a platform that ran from 1991 to 2017 and gave us some of the most beloved models in the Harley lineup. From the stripped-down Street Bob to the long-forked Wide Glide, every Dyna is built around the same exposed dual rear shock chassis and rubber-mounted V-twin. That engine is part of the appeal, but it also creates a real challenge when it comes to mounting a phone. The low-frequency rumble and high-frequency buzz a Twin Cam produces will shake apart any phone mount that wasn’t designed for it. Get the wrong mount and you will hear it rattling before you hit the end of your street.
This guide covers the mounts that actually hold up on a Dyna, whether you’re riding a stock Street Bob with 1-inch bars, a Wide Glide with extended forks, or a custom-bar Fat Bob. We’ll break down which option fits which sub-model and give you the information you need to make the right call for your specific bike.
Harley-Davidson Dyna Sub-Models: A Quick Reference
The Dyna platform spans dozens of configurations across more than two decades of production. While they all share the same basic chassis, the handlebars and front ends vary significantly between sub-models. That matters for mounting because bar diameter and style directly affect what clamp base you need.
Here is the full Dyna family:
- FXD Dyna Super Glide (1995-2010): the base model, clean and stripped down with standard 1-inch handlebars
- FXDB Dyna Street Bob (2006-2017): minimalist bobber styling with mini-ape handlebars, typically 1-inch to 1-1/4-inch diameter
- FXDC Dyna Super Glide Custom (2005-2014): similar profile to the base Super Glide with a slightly more dressed look
- FXDL Dyna Low Rider (1993-2017): low-slung with a slightly wider bar stance, typically 1-inch bars on most years
- FXDWG Dyna Wide Glide (1993-2017): wide front fork spacing, longer rake, buckhorn or ape-hanger bars on many years, common in 1-inch to 1-1/4-inch range
- FXDF Dyna Fat Bob (2008-2017): dual headlights, fat front tire, often fitted with drag bars or fat ape hangers that can run 1-1/4-inch to 1-1/2-inch diameter on aftermarket setups
- FXDS-CONV Dyna Convertible (1994-2000): touring-leaning model with saddlebags, standard bars
- FXDX Dyna Super Glide Sport (1999-2005): performance-tuned with sportier suspension, standard 1-inch bars
- FLD Dyna Switchback (2012-2016): sport-touring configuration with quickly detachable fairing and bags
For most stock Dyna models, your handlebar diameter will be 1 inch or 1-1/4 inch. If you have swapped to aftermarket bars, especially on a Fat Bob or Wide Glide, you may be running 1-1/4-inch to 1-1/2-inch bars, or even wider on fully custom setups. Check your actual bar diameter before ordering any clamp-style mount.

Tackform 20MAXX Chrome – Best for Stock Dyna Bars
Tackform leads this list because the Dyna community cares about how things look, and the 20MAXX Chrome is one of the few phone mounts that doesn’t look like an afterthought bolted to your handlebars. Every component is CNC-machined 6061-T6 billet aluminum. The chrome finish matches the factory hardware on most stock Dyna models well enough that it doesn’t fight the aesthetic of the bike. The short-reach arm keeps the phone tucked close to the bars rather than floating out on a long stalk.
The clamp range here is 7/8 inch to 1-1/4 inch, which covers virtually every stock Dyna model from the base Super Glide through the Street Bob and Low Rider. The spring-loaded cradle uses a calibrated compression spring that lets you pop the phone in and pull it out with one hand. The octagon-shaped rubber grips on the cradle hold the phone securely and pull it slightly away from the back plate on hot days to reduce heat transfer to the device. Anti-rattle pin sleeves eliminate the cradle buzz that shows up in cheaper spring mounts over time.
The 20MAXX uses Tackform’s proprietary 20mm ball system, which is not cross-compatible with the RAM 1-inch ball platform. Everything you need is in the box for a complete install. No hunting down adapters, no separate cradle purchase. That self-contained approach works well for most riders who want to mount and go.
Tackform 20MAXX Black (1-1/4″ to 1-1/2″ Bars) – Best for Fat Bob and Wide Glide
The Fat Bob and Wide Glide are the two Dyna models most likely to have non-standard bars, whether from the factory or from an aftermarket swap. The FXDF Fat Bob came from Harley with a wider front end and drag-bar style handlebars that tend to run at the higher end of the diameter range. The Wide Glide is popular as a custom platform, and a lot of riders upgrade to ape hangers or broader bars that exceed the 1-1/4-inch cap on the standard-clamp version of the mount.
The large-bar version of the 20MAXX uses the same billet aluminum cradle and short-reach arm as the chrome model but with a clamp designed specifically for 1-1/4-inch to 1-1/2-inch handlebars. Bushings are included for a secure fit at each diameter in that range. The finish is matte black, which suits the blacked-out Fat Bob and Wide Glide builds that are common in the Dyna community.
Build quality is the same across both Tackform models: stainless steel compression springs, anti-rattle sleeves, and enough clamping force to stay put through sustained engine vibration at highway speeds. For riders who are running aftermarket bars from brands like LA Choppers, Factory 47, or Bandit, this is the version to buy.
RAM X-Grip with U-Bolt Handlebar Base – Best for Maximum Adjustability
RAM Mounts has been the benchmark for motorcycle device mounting for decades, and the X-Grip with U-Bolt base is the combination that has lived on Dyna handlebars longer than almost any other configuration. The U-bolt base clamps around the handlebar and is secured with two bolts, giving it a more solid connection than a simple split-clamp design. It accommodates bars from 0.5 inch to 1.25 inch in diameter, covering every stock Dyna handlebar that left the factory.
The X-Grip cradle uses four spring-loaded arms that expand and contract to fit the phone. Unlike a case-specific system, the X-Grip works with whatever phone you have, in whatever case it is currently in. Phones from 1.875 inches to 3.25 inches wide are supported, which covers everything from a compact iPhone to a large Android flagship. RAM’s rubber ball and socket system allows the arm to be repositioned at both ends, giving you near-infinite adjustment to dial in the exact angle you want. A safety tether is included and is worth attaching every time for highway riding.
The materials are marine-grade powder-coated aluminum, stainless steel, and high-strength composite. That combination handles the combination of engine heat, vibration, and weather exposure that any mount sees on a motorcycle over thousands of miles. RAM also backs the system with a lifetime warranty. Because the RAM platform is fully modular, you can swap bases, arms, and cradles independently as your needs change.
Quad Lock Motorcycle Handlebar Mount – Best Case-Lock System
Quad Lock takes a different approach from every other mount here. Instead of a universal cradle that grips any phone, the Quad Lock system requires a Quad Lock case or adhesive adapter on your phone. Once you have the case, the phone connects to the mount through a patented dual-stage twist lock. You twist to attach, twist back to release. There is no spring tension, no cradle grip, no secondary tether needed. The phone is mechanically locked to the mount, and it stays there.
For Dyna riders, that level of security is appealing. The vibration from a high-displacement V-twin at idle is enough to work a spring-loaded cradle loose over time. The Quad Lock eliminates that variable entirely. The handlebar mount uses a machined aluminum clamp that rotates through 360 degrees for landscape or portrait positioning, and the locking head separates cleanly from the base when you get off the bike.
Quad Lock strongly recommends pairing this mount with their Vibration Dampener when using it on any motorcycle. This is a small rubber-isolated adapter that sits between the mount base and the locking head, reducing the high-frequency vibration that can damage the optical image stabilization in newer phone cameras. On a Dyna, that recommendation is worth taking seriously. The dampener is sold separately and is not included with the base mount.
The case requirement is the trade-off to understand before buying. If you already use a slim or naked phone without a case, you will need to either adopt the Quad Lock case or use the adhesive universal adapter. That adapter bonds to the back of your existing case using 3M VHB adhesive and works well, but it is a single-use application.
JOYROOM Dual Vibration Dampener Mount – Budget Pick
Not every Dyna rider wants to spend close to a hundred dollars on a phone mount. The JOYROOM dual vibration dampener mount is the budget option on this list, and it earns its spot by addressing the one thing budget mounts usually get wrong: vibration. The dual dampener system uses a pneumatic shock-absorbing structure at both the handlebar connection and the phone cradle itself, which the manufacturer states can absorb up to 95 percent of high-frequency engine vibration. For a Harley application, that design choice matters more than almost any other specification on a lower-priced mount.
The 2026 version features an all-metal tie rod and all-metal core ball heads, which addresses the plastic flex that was a weak point in earlier JOYROOM designs. The handlebar clamp covers bars from 0.79 inch to 1.38 inch in diameter. Phone loading uses a one-second center-button press-to-lock system with no fiddling with spring arms. Phones up to 7 inches tall and 3.54 inches wide are supported, which covers virtually every phone currently on the market including large Pro Max and Galaxy Ultra models.
The metal extension arm includes a 720-degree rotating ball head for flexible positioning. A hex wrench is included for installation. JOYROOM backs this mount with a 36-month warranty, which is unusually generous for a budget option in this category.
What to Know Before Buying a Phone Mount for Your Dyna
The Dyna platform presents a few specific mounting considerations that general motorcycle phone mount guides do not always address. Here is what matters most for this family of bikes.
Bar diameter is not universal across Dyna sub-models. Most stock Dyna models use 1-inch bars. The Fat Bob and Wide Glide often run larger diameters at the factory, and any bike with aftermarket handlebars may be anywhere from 7/8 inch to 1-1/2 inches or beyond. Measure your bars before ordering a clamp-style mount. Using a clamp that is too large or too small will result in either a loose mount or an installation that won’t seat properly.
The Twin Cam engine produces serious vibration. The Evolution and Twin Cam engines in the Dyna platform are rubber-mounted, which reduces but does not eliminate vibration transfer to the handlebars. At highway speeds, a cheap mount with no vibration management will rattle constantly and may damage your phone’s camera stabilization hardware over time. Every mount on this list addresses vibration in some form, whether through rubber ball sockets, dampener pads, or dedicated pneumatic systems.
Ape hanger bars require a different approach. If your Dyna has tall ape hangers or pullback risers, the mounting angle changes. Many clamp mounts assume a relatively horizontal bar. On steep ape hangers, you may need to choose a mount with a longer reach arm or more ball socket adjustability to position the phone at a viewable angle without it pointing at the sky.
The 2017 production cutoff means these are used bikes. The Dyna platform ended production in 2017, which means any Dyna on the road today is at minimum several years old. Many have been modified. Standard clamp specs may not apply if the previous owner swapped bars, risers, or hardware. When in doubt, measure and confirm before buying.
Frequently Asked Questions
What handlebars do Harley-Davidson Dyna models have?
Most stock Dyna models use 1-inch diameter handlebars. The Fat Bob (FXDF) and Wide Glide (FXDWG) from certain years, as well as any model with aftermarket bars, may use 1-1/4-inch to 1-1/2-inch diameter bars. Always measure your actual bar before purchasing a handlebar-clamp phone mount.
Will a standard motorcycle phone mount work on a Harley Dyna?
Yes, provided you choose a mount with a clamp range that covers your bar diameter and a design that handles vibration. Cheap plastic spring mounts from generic brands are not recommended for any Harley application. The V-twin vibration will expose weak materials and poor engineering within a season of regular riding.
Is the Harley-Davidson Dyna still in production?
No. Harley-Davidson discontinued the Dyna platform after the 2017 model year. All remaining Dyna models were absorbed into or replaced by the updated Softail platform, which uses a similar hidden rear shock setup with the Milwaukee-Eight engine series. There is no 2018 or newer Dyna.
Should I use the vibration dampener with a Quad Lock on my Dyna?
Yes. Quad Lock specifically recommends the Vibration Dampener for any motorcycle application, and on a high-displacement V-twin like the Dyna’s Twin Cam, that recommendation carries extra weight. The dampener reduces high-frequency vibration that can degrade the optical image stabilization in modern smartphones. It is sold separately and is worth the additional cost.
Do any of these mounts work for a Harley-Davidson Sportster or Softail too?
The RAM X-Grip and both Tackform models will work on a Sportster or Softail provided your bar diameter falls within the clamp range. These are not Dyna-specific mounts. They are universal motorcycle handlebar mounts that work across virtually any bike with handlebars in the supported diameter range.
