Some owners report premature wear of rear wheel bearings, especially with heavy loads or aggressive riding.
Heritage:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer renowned for its V-twin engines, distinctive styling, and rich racing history. The brand has a massive global following and a strong association with freedom and the open road.
Evolution Of Dyna:
The Dyna platform, introduced in 1991, was designed to offer a more modern ride compared to the older FXR and Big Twin models, featuring a more rigid frame and improved handling. The FXDXI Super Glide Sport represented an evolution within the Dyna line, specifically targeting riders who desired a more performance-oriented and agile motorcycle.
Production Period:
The FXDXI Dyna Super Glide Sport was produced from 2004 to 2005, before being replaced by the FXDCI Super Glide Custom in some aspects, with the FXDXI nameplate being retired.
Engine Progression:
The Twin Cam 88 engine was a significant departure from Harley's Shovelhead and Evolution engines, offering increased displacement and a more refined, yet still characterful, V-twin experience. The 1450cc displacement was the standard for most Harley models in this era.
