Harley-Davidson’s 105th Anniversary Wide Glide was a special 2008 model-year commemorative edition of the Dyna Wide Glide, built to mark the company’s 105th anniversary. It sat within the Dyna family and used the Wide Glide’s familiar long-and-low, chopper-inspired stance, but it was presented as a limited anniversary variant rather than a separate long-running sub-brand. Harley-Davidson’s own 2008 Dyna service documentation identifies the model code for the FXDWG Wide Glide 105th Anniversary and places it in the 2008 model year, confirming it as a one-year anniversary offering.
The Wide Glide name itself has deeper Harley-Davidson roots. Harley-Davidson’s official Dyna history traces the Wide Glide back to 1980 in the FX line and notes that the Wide Glide joined the Dyna family in 1993. The 105th Anniversary version belongs to that later Dyna-era lineage, but it is specifically tied to the 2008 anniversary program and does not appear to have continued beyond that model year. In other words, this was a commemorative edition of an established Harley-Davidson nameplate, not a separate multi-year production series.
For enthusiasts, the model is significant because it combines one of Harley-Davidson’s classic cruiser silhouettes with the collectible appeal of a numbered anniversary release. Its place in the lineup reflects Harley-Davidson’s practice of using anniversary editions to highlight heritage models while giving them distinct paint, badging, and trim that set them apart from standard production bikes.
