1. Brief History of DYNA Street Bob FXDB

The modern Harley Dyna Street Bob was produced in 2006 as a throwback to the bobber. Right after World War II, these bikes became very popular, because these were actually the military bikes used in War. All Harleys that could be found in the U.S were equipped with military equipment like rifle mounts and ammunition boxes.


Civilians stripped them down for their casual use. In those times, the process of trimming them down and modifying those bikes was called “Bobber.” People see the lighter and prettier bikes after stripping them down because these bikes can be trimmed down to the bare minimum essentials. Harley-Davidson took the maximum advantage of this bike's popularity and sold out maximum units within a very short period of time.


There are a variety of changes that can be seen between the old and the new model. Though the classy look of this bike is still at sky limits and the low solo seats, fat tires, classic ape hanger handlebars, very well-known fat Bob fuel tanks took the minimalistic approach of the Harley Dyna SB to the heights.
