The Dyna Street Bob was Harley-Davidson’s stripped-down bobber interpretation within the Dyna family, introduced for the 2006 model year. It arrived as part of the company’s broader Dyna lineup and quickly became known for its minimalist factory-custom attitude: a solo-seat stance, chopped rear fender, blacked-out details, and a deliberately simple, old-school look that echoed the bobber and chopper scene rather than Harley’s more traditional touring or chrome-heavy cruiser styling. In Harley-Davidson’s own historical materials, 2006 is identified as the first year of the FXDB Street Bob, and the model remained part of the Dyna range through the end of that platform.
Over time, the Street Bob became one of the most recognizable Dyna variants, occupying a sweet spot for riders who wanted a leaner, more aggressive Harley without moving into the more extreme custom or performance-oriented corners of the lineup. It represented the Dyna family’s factory-custom side: visually simplified, easy to personalize, and closely tied to the brand’s long-running bobber aesthetic. By the end of the Dyna era, the model was still carrying the same basic identity that made it distinctive at launch.
Harley-Davidson officially retired the Dyna family in 2017, with several Dyna model names and styling cues later carried into the redesigned Softail line for 2018. For that reason, the Dyna Street Bob’s continuous production run is best understood as ending with the 2017 model year, even though the Street Bob name itself continued in a different platform afterward.
