Historical Context

The 2005 Harley-Davidson FXDI Dyna Super Glide represented the latest chapter in a storied lineage that began in 1971, when Harley introduced the Super Glide as its first factory custom. By 2005, the Dyna platform had become known for blending classic Harley styling with improved frame geometry, rubber-mounted engines, and solid long-distance performance. The FXDI variant offered fuel injection (denoted by the "I"), making it one of the most refined Super Glides to date. Sitting just below the Wide Glide and Street Bob in the Dyna range, the FXDI appealed to riders looking for stripped-back, no-nonsense American V-twin power without unnecessary weight or bulk. With its clean lines, reliable Twin Cam 88 engine, and classic silhouette, the 2005 FXDI was a modern Harley with deep roots in the brand’s history.

Technical Advancements

The key upgrade for the 2005 FXDI was its factory fuel injection system, improving cold starts, throttle response, and long-term reliability. The Twin Cam 88 engine had already proven itself over the previous five years as a durable, smooth-running powerplant. Rubber-mounted to reduce vibration, it allowed longer rides with less fatigue. The FXDI also benefited from improved wiring, upgraded brakes, and a more modern instrument cluster compared to earlier Dynas. Its clean styling, mid-mount controls, and slightly pulled-back handlebars offered a neutral riding position suitable for both commuting and light touring.

Evolution of the Model

The Super Glide has always been a minimalist platform—essential Harley with no frills. Over the years, it evolved from the Shovelhead-powered AMF era bikes to the much more refined Twin Cam generation. The FXDI took all the lessons learned from previous generations and added modern touches without compromising the stripped-back aesthetic. It served as a great base for customization while also being a solid performer in factory trim. Later Dyna models would adopt the larger 96ci and 103ci motors, but the 88ci in the FXDI remains a sweet spot for many riders who want balance over brute force.

Competitors in the Market

In 2005, the FXDI faced off against Japanese cruiser rivals like the Yamaha Road Star, Honda VTX1300, and Kawasaki Vulcan 1600. These bikes offered more horsepower or additional creature comforts, but none matched the FXDI’s heritage, riding character, and massive aftermarket support. The Harley still stood apart with its unmistakable V-twin rumble, solid road presence, and the kind of torque that only Milwaukee iron can deliver.

Legacy and Appeal

Today, the 2005 FXDI Dyna Super Glide is a popular choice for riders looking for a fuel-injected, mid-2000s Harley with classic lines and proven reliability. It makes an ideal project bike, daily rider, or entry point into the Harley world. Whether kept original or modified into a bobber, club-style Dyna, or mild custom, the FXDI holds its value and delivers that genuine Harley experience. It’s a perfect blend of modern engineering and timeless simplicity—an under-the-radar classic in the making.
