The 2004 Harley Davidson Dyna Super Glide bridges the gap between raw, stripped-down styling and everyday rideability. Positioned as an accessible entry point to big-twin cruising, it gives riders a raw mechanical feel without punishing them on longer stretches of highway. If you're looking at one today as a used bike purchase or studying its engineering evolution, understanding its unique place in Harley's modern history helps separate factory reality from forum myths.
Engine Specs and Performance
The beating heart of the 2004 Super Glide is the Twin Cam 88 engine, displacing 88 cubic inches (1,450cc). Unlike the older Evolution engine found in earlier models, the Twin Cam features dual chain-driven camshafts and puts out roughly 67 horsepower and around 81 foot-pounds of torque at 2,900 RPM.
- Displacement: 1,450cc (88 ci) air-cooled V-twin
- Fuel System: Delphi Electronic Sequential Port Fuel Injection (ESPFI) or traditional Keihin carburetor
- Transmission: 5-speed Cruise Drive transmission
- Final Drive: Kevlar reinforced belt
Power delivery hits low in the rev range, making stoplight acceleration effortless. The five-speed transmission shifts with a distinct mechanical clunk that riders either love or learn to live with. Fuel economy hovers around 40 to 45 miles per gallon under mixed riding conditions, yielding a solid cruising range from its 4.9-gallon fuel tank.
Frame, Handling, and Chassis
The Dyna chassis is built around a distinct backbone frame that separates it from Softail and Touring models. Rubber engine mounts isolate engine vibration at cruising speeds while letting the motor pulse authentically when idling at a stoplight.
Handling is nimble compared to heavier touring rigs. With a rake of 29 degrees and a relatively lightweight dry weight of around 617 pounds, the Super Glide loves sweeping backroads. Cornering clearance is decent for a cruiser, though aggressive riders will easily scrape the footpeg feelers on tighter mountain hairpins.
Stopping duties are handled by single-disc brakes front and rear with four-piston calipers. While adequate for the bike's weight, modern riders accustomed to ABS and dual front rotors will want to apply firm pressure to both levers during emergency stops.
Ergonomics and Rider Comfort
Stock ergonomics favor an upright, relaxed riding posture. Mid-controls come standard on the base Super Glide (FXDI), keeping your feet positioned directly beneath you for active control, though many owners swap these out for forward controls.
The stock two-up seat is comfortable for hour-long commutes, but foam breakdown is common on surviving examples today. If you're buying a used 2004 model, budget for an aftermarket seat from brands like Mustang or Saddlemen if you plan on weekend touring. Passenger accommodations are minimal; the rear pad is small, so plan on aftermarket upgrades if you ride two-up frequently.
Common Issues and Maintenance
Finding a clean used model requires checking a few known trouble spots unique to early-2000s Harley architecture:
- Cam Chain Tensioners: Spring-loaded plastic shoe tensioners on early Twin Cam motors wear down over time. Inspect them every 20,000 miles or upgrade to hydraulic tensioners or gear drives to prevent catastrophic engine failure.
- Primary Chain Adjuster: Manual adjusters require periodic checks to prevent excessive primary noise and wear.
- Electrical Grounding: Corroded ground wires behind the front console or under the seat can cause intermittent instrument cluster failures or starting hiccups.
Routine maintenance is straightforward for home mechanics. Changing the engine oil, primary fluid, and transmission fluid requires basic hand tools and an afternoon in the garage. For official technical specifications and parts diagrams, consult the Harley-Davidson Service Portal.
Buying Guide: What to Look For Today
Prices for a well-maintained 2004 Super Glide generally range from $4,000 to $7,000 depending on mileage, condition, and aftermarket modifications. When inspecting a candidate:
- Check Service Records: Look for proof of cam tensioner inspections or upgrades.
- Inspect Chrome and Paint: Factory clearcoat on early 2000s models can bubble or flake if left exposed to harsh coastal air.
- Verify Stock vs. Modified: Modified exhaust and air intakes are common. Ensure a proper fuel tuner (like a Power Commander) was installed to prevent lean running conditions.
Frequently Asked Questions
Is the 2004 Dyna Super Glide good for beginners?
Its manageable weight and low seat height make it approachable, but the heavy clutch pull and torque-heavy V-twin require respect. It's better suited for riders with some basic two-wheel experience than absolute novices.
Does the 2004 model have carburetor or fuel injection?
Harley offered both options in 2004. You can find models equipped with the traditional Keihin carburetor or the optional Delphi Electronic Sequential Port Fuel Injection (ESPFI). Fuel-injected models generally command a slight price premium on the used market.
How does the Super Glide differ from the Wide Glide?
The Super Glide features a tighter steering geometry, mid-controls, and a narrower front end, giving it sharper handling characteristics. The Wide Glide uses raked-out front forks, a 21-inch front wheel, and forward controls for a traditional chopper stance.
What is the fuel capacity of a 2004 Super Glide?
The fuel tank holds 4.9 gallons (18.5 liters), including a 1.0-gallon reserve, which comfortably supports around 180 to 200 miles of highway riding between fill-ups.
