The Harley Davidson Dyna was first introduced in '91 with the FXDB Sturgis that was available in limited quantities. In '92 the line of Dyna Models was continued with other dyna models being released. The Dyna features a Big Twin engine and traditional frame styling. This model Harley can be distinguished from the Softail by the traditional coil-over suspension that connects the swingarm to the frame, and from the Sportster by their larger engines. At Deadbeat Customs the Dyna is a favorite of ours, it's my personal daily driver and a favorite among Harley stunt riders. From hanging wheelies to scraping footpegs in the corners, the Dyna is worthy of it's own Dyna Parts category at Deadbeat Customs.
