1991 Harley-Davidson FXDB Dyna Glide Sturgis Anniversary Motorcycle
|Engine||Twin cylinder, 80-cid|
For 1991, Harley-Davidson redesigned the Dyna Glide using CAD technology to create a new, stiffer steel frame. The 80-cid V-Twin engine was mounted at a different angle and slightly forward to give a longer, lower look - also achieved by relocating the oil tank (now operated with an internal pump) beneath the transmission.
The redesigned exhaust system also meant the belt drive could be more easily accessed and replaced. Other changes included new rear fork mounts, a 32-degree front rake, 19-inch front and 16-inch rear cast alloy wheels with disc brakes. The speedometer was found in a console mounted on the tank, itself now with twin filler caps. The new frame of the Dyna Glide was a major improvement over the older FX models - the two-point engine-mounting system far more effective than the old four-point rubber-damping set-up - and was progressively adopted across the FX series during the early 1990s. The first model to use the system was the FXDB Sturgis, named after the annual bike rally held in North Dakota, a limited edition version all of which were finished in black.
