You see them everywhere. Usually, it’s a blur of black paint, a high-set T-bar, and that distinct, aggressive 2-into-1 exhaust rasp. The custom Harley Dyna Super Glide has become the unofficial poster child for "cool" in the modern V-twin world. But if you think this bike is just a prop from a TV show or a trendy West Coast fad, you're missing the point entirely.
Honestly, the Dyna Super Glide is probably the most honest motorcycle Harley-Davidson ever built. It wasn't a "couch on wheels" like the Electra Glide, and it wasn't trying to be a dainty cruiser. It was basically a Sportster on steroids—a Big Twin engine stuffed into a frame that actually liked to lean.
The Blank Canvas That Actually Handles
When the FXD Dyna Super Glide hit the scene in the early 90s, it took over for the legendary FXR. People were skeptical. The FXR was a handling master, designed with help from Eric Buell. The Dyna? It was simpler. More "Harley." But what it lacked in CAD-designed frame geometry, it made up for in raw versatility.
The Super Glide was the "base model" of the Dyna family. That sounds like a negative, but for customizers, it was a godsend. You didn't have to pay for the chrome you were going to swap anyway. You didn't have the "wide" front end of the Wide Glide that slowed down your steering. You got a narrow-glide front end, a mid-mount control setup, and a chassis that felt connected to the road.
Why the 2006-2017 Era is King
If you’re hunting for a project, the 2006 model year was a massive turning point. Harley updated the frame, moved to a 49mm front fork (way stiffer than the old 39mm), and finally gave us a six-speed transmission.
Most riders look for the 2012-2017 models because of the Twin Cam 103 engine. It’s got that extra grunt. But don’t sleep on an older 88-inch or 96-inch Twin Cam if the price is right. You’re going to swap the cams anyway. Just sort out those early cam chain tensioners—a well-known "Harley Tax" detail—and those engines will outlive most of us.
The Performance Dyna Movement
The "Club Style" look is what most people mean when they talk about a custom Harley Dyna Super Glide these days. It’s a style born out of necessity by Northern California riders who needed to split lanes and outrun... well, whatever they were outrunning.
It isn't just about looking like Jax Teller. It's about performance.
- Suspension is everything. Throw away the stock rear shocks. They're trash. Most serious builders go for 13-inch or 13.5-inch Legend, Ohlins, or Fox shocks. This lifts the rear, quickens the steering, and gives you actual ground clearance for corners.
- The T-Bar setup. High risers (10 to 14 inches) aren't just for show. They put your hands in a position that allows for way more leverage over the front end. It makes the heavy bike feel flickable.
- The 2-into-1 Exhaust. Brands like Bassani, Sawicki, or Trask are the go-to. You want that scavenge effect for torque. Plus, it tucks up high so you don't scrape it when you're dragging pegs.
What Nobody Tells You About the "Softail Takeover"
In 2018, Harley killed the Dyna. They merged it into the Softail line.
Purists lost their minds. "The Dyna is dead!" they screamed. And yeah, the new Softail frame is objectively better—it’s lighter and stiffer. But it doesn't have the soul. The Dyna has those exposed twin shocks. It has that rubber-mounted engine that shakes your teeth loose at a stoplight but smooths out into a magic carpet at 80 mph.
That’s why the market for a used Super Glide is insane right now. People want that mechanical connection. They want to feel the engine moving in the frame. A custom Dyna is a living thing. It's messy, it's loud, and it's sort of perfect because of those flaws.
Avoiding the "Boutique" Trap
Don't get sucked into the trap of thinking you need $10,000 in carbon fiber parts to have a "real" custom Dyna.

I’ve seen guys spend a fortune on Kraus front ends and carbon wheels only to ride the bike once a month to a coffee shop. That's fine if that's your thing. But the best Super Glides are the ones that look a little beat up. A bike with some road rash on the primary cover and a seat that’s been worn down from 50,000 miles of touring tells a much better story.
Real-World Upgrades You’ll Actually Notice
- Brakes. The stock single-disc front brake on many Super Glides is, frankly, terrifying. Upgrading to a dual-disc setup or at least a high-quality Brembo or Arlen Ness big rotor kit is the best money you'll ever spend.
- The Seat. The stock seat is a torture device. Saddlemen and BMC are the industry standards for a reason. You need that "step-up" to keep you from sliding off the back when you whack the throttle.
- The Lighting. The old halogen bulbs are basically candles in the wind. A MoonsMC or Bung King LED setup is a safety requirement, not a luxury.
Actionable Next Steps for Your Build
If you’re sitting on a stock Super Glide or looking to buy one, don't rush into a full teardown.
Start with the ergonomics. Sort out the bars and the seat first. Ride it for a month. See where the bike feels lacking. If it feels "mushy" in the turns, do the rear shocks. If it feels sluggish, do a Stage 1 (intake, exhaust, tuner).
Check your local listings for 2007-2011 FXDC (Super Glide Custom) models. They often go for less than the "Street Bob" because they have more chrome, but underneath, they're the same platform. You can black them out yourself and save three grand.
Look for signs of the "death wobble" at high speeds—this is usually just worn-out motor mounts or a misaligned rear wheel. Replacing the mounts with a Predator or Sputhe stabilizer kit is a weekend job that transforms the bike's stability.
Stop worrying about what’s "correct" for the style and just build the bike that makes you want to take the long way home.
