The Harley-Davidson Street Bob has gone through a significant transformation since it was first introduced. The original Dyna-chassis Street Bob was replaced in 2018 with an all-new Softail-platform FXBB that is lighter, more agile, and considerably more refined. The 2026 model now runs the Milwaukee-Eight 117 engine. If you are looking at older mounting advice for the Street Bob, most of it was written for the Dyna generation and does not fully account for the current model’s mini-ape handlebars, updated cockpit layout, and the brake reservoir mounting options that have become the preferred setup for current Street Bob riders.
This guide covers the best phone mounts for both generations of the Street Bob, with specific attention to the current FXBB Softail platform and what works best on it.

Street Bob Model History: Which Generation Do You Have?
Knowing which generation Street Bob you own matters for mount selection, particularly for the brake reservoir location.
The original Street Bob (FXDB, 2006-2017) was built on the Dyna chassis with a more traditional naked cruiser layout. The handlebars were wider and more upright, and while the handlebar position was excellent for phone mounting, the brake reservoir location on that generation has different hardware than the current Softail platform.
The current Street Bob (FXBB, 2018-present) moved to the lighter Softail platform with mini-ape handlebars, a revised cockpit, and the Milwaukee-Eight engine. The 2021 model year added the FXBBS designation with the 114 cubic inch engine, and the 2026 model runs the Milwaukee-Eight 117. All FXBB generation models share the same mounting approach and the same brake reservoir bolt pattern, so all of the mounts below apply equally across the current generation.
Best Overall: Tackform Brake Reservoir Mount with Phone Cradle
The brake reservoir mounting location has become the most popular choice for current Street Bob riders who want a clean, factory-integrated look. The existing brake reservoir bolts on the right side of the handlebar are replaced with slightly longer stainless steel bolts that accommodate the added depth of the mount base. The result is a phone that sits within the rider’s natural sightline without adding anything to the handlebars themselves.
The Tackform reservoir mount with phone cradle is CNC machined from billet aluminum with stainless steel hardware. The 20MAXX spring-loaded cradle holds any phone in any case up to 3.7 inches wide, and the 3.5-inch reach arm positions the phone at a comfortable distance from the reservoir. The 20mm ball-and-socket connection allows full angle adjustment after installation. The Street Bob’s mini-ape bars put the hands in a natural position that makes the reservoir location easy to glance at without looking away from the road for longer than a moment.
Harley-Davidson forum members consistently recommend Tackform as one of the top two reservoir mount solutions for Softail models. The billet aluminum construction and black or chrome finish options blend with the Street Bob’s styling rather than looking like an afterthought bolted onto the controls.

Best for GPS and Modular Setups: Tackform Reservoir Ball Mount
If you want to mount a Garmin GPS at the reservoir location, or if you prefer to build a modular setup that lets you swap between different holders, the Tackform reservoir ball mount is the base-only version. It installs the same way as the complete cradle version but terminates in a 20mm ball instead of a phone cradle. From the ball you can add any compatible phone holder, Garmin GPS cradle, RAM adapter, or other accessory.
For Street Bob riders who use a Garmin Zumo motorcycle GPS or a Garmin Drive automotive GPS, this base gives you a clean reservoir mounting point that accepts the GPS cradle’s 17mm socket with a standard adapter. The billet aluminum construction is the same quality as the complete cradle version.

Best Handlebar Mount: RAM X-Grip Kit
The Street Bob’s 1.25-inch handlebar has generous real estate on both sides of the stem, and the mini-ape bar shape puts the mounting position in a natural, easy-to-see location. For riders who prefer the handlebar position, the RAM X-Grip kit is the most proven option for this bar diameter.
The complete kit includes the U-bolt handlebar base, a double socket arm, and the spring-loaded X-Grip cradle. The U-bolt hardware fits the standard 1.25-inch Harley handlebar without any adapter. The X-Grip cradle holds phones from 1.875 to 3.25 inches wide in any case and includes a safety tether. RAM backs all their motorcycle mounts with a lifetime warranty.
For larger current iPhone Pro Max and equivalent Android models, the RAM X-Grip Large kit (B01MU4X7UZ) uses the same handlebar base but a wider cradle that handles up to 4.5 inches wide. Both versions are fully interchangeable at the handlebar base.

Best Premium Handlebar Option: Quad Lock Handlebar Mount
For Street Bob riders who want the most secure phone connection at the handlebar, the Quad Lock handlebar mount is the premium choice. The mount clamps to the 1.25-inch bar using the included 32mm spacer and the dual-stage twist-lock mechanism provides a physical lock rather than a spring or magnetic hold. The phone cannot vibrate free from the mount regardless of road surface or riding conditions.
Quad Lock offers both black and chrome finish options. The chrome version is worth considering for Street Bob builds that run chrome controls and accents throughout. An extension arm is included that lifts the phone slightly off the bar for better sightline clearance on the mini-ape setup.
As with all Quad Lock products, a compatible case or universal adapter is required. If you already use Quad Lock on another bike or in a vehicle, adding the Street Bob mount to your ecosystem is straightforward.

What to Avoid on the Street Bob
Cheap bicycle-style handlebar clamp mounts. The Street Bob’s 1.25-inch bar will accept many bicycle handlebar mounts mechanically, but bicycle mounts are not built for the vibration levels of a V-twin engine. They crack, loosen, and fail in ways that result in phones hitting the road at speed. Use motorcycle-rated mounts only.
Suction cup mounts on any surface. Engine vibration loosens suction cup bonds over time, and the Milwaukee-Eight generates enough low-frequency vibration to compromise suction cup adhesion on longer rides. Skip this approach entirely.
Tank bag magnetic mounts. The Street Bob’s minimalist bobber aesthetic does not suit a tank bag, and magnetic tank mounts can interfere with paint over time. The handlebar and reservoir locations are both superior options.
Frequently Asked Questions
What diameter are the Street Bob handlebars?
The stock Street Bob handlebars are 1.25 inches in diameter on both the original Dyna generation and the current Softail FXBB. This is the standard Harley cruiser handlebar diameter and is compatible with most motorcycle handlebar mounts without any adapter.
Does the brake reservoir mount work on both Dyna and Softail Street Bob models?
The reservoir bolt pattern is similar across Harley Softail and Dyna models, but the hardware included in mount kits is typically optimized for one platform or the other. Tackform lists compatible models on their website. Confirm your specific year and model before ordering any reservoir mount.
Is the mini-ape handlebar on the current Street Bob good for phone mounting?
Yes. The mini-ape bars on the current FXBB sit at a comfortable height and angle that positions a handlebar-mounted phone naturally within the rider’s sightline. The wider spread of the bars also provides more mounting location options than a flat or drag bar setup.
Do I need a vibration dampener on the Street Bob?
The Milwaukee-Eight engine in the current Street Bob is significantly smoother than older Harley engines due to its counterbalancing system. Most riders do not experience problematic phone vibration at normal riding speeds. If you use a current iPhone and ride frequently, a Quad Lock vibration dampener is still worth adding given Apple’s guidance on motorcycle vibration and camera OIS hardware.
Will these mounts work on the Street Bob 114 and 117?
Yes. The FXBBS Street Bob 114 and the current Street Bob 117 share the same chassis, handlebar dimensions, and brake reservoir hardware as the standard FXBB. All mounts in this guide are confirmed for all engine variants of the current Softail Street Bob.
Can I mount a Garmin GPS on the Street Bob?
Yes. The Tackform reservoir ball mount with a Garmin-compatible adapter is the cleanest setup for GPS use on the Street Bob. The RAM X-Grip cradle also accommodates smaller Garmin automotive GPS units up to about 5 inches in screen size. For a dedicated motorcycle GPS like the Garmin Zumo, use the motorcycle-specific mount hardware that ships with the Zumo unit.
