Harley-Davidson Super Glide - Dyna

Dyna

Design work began on the replacement for the FXR chassis shortly after the first FXR bikes were offered. The Dyna chassis was introduced in 1991 with a limited-production FXDB Sturgis model. The engine mounting system was changed from three rubber mounts to two, resulting in poorer vibration control, but speedier production on the assembly line.

The Sturgis was followed in 1992 by the limited-edition FXDB Daytona. Also introduced in 1992 was the FXDC Dyna Glide Custom. Apart from the paint scheme, the Dyna Glide Custom was virtually identical to the Daytona. Dyna Customs were all painted black and silver, and the early models featured a silver powder coat on the frame. Later production units featured a black frame.

In 1993 the faired and bagged FXRT Sport Glide was discontinued and the FXRS Low Rider was displaced by the FXDL Dyna Low Rider, although the FXR, FXLR, FXRS-Conv Convertible and the FXRS-SP Low Rider Sport continued to be offered. The FXDWG Dyna Wide Glide was introduced in the same year. The Low Rider Sport was discontinued in 1994, and the Low Rider was discontinued after the 2009 model year.

Between the 1991 introduction of the Dyna chassis and the end of the 1994 model year, all Dyna models had a 32° rake. In 1995 the FXD Dyna Super Glide and the FXDS-Conv Dyna Glide Convertible were introduced. These Dynas had a 28° rake and replaced the FXR Super Glide and the FXLR Low Rider Custom, which were the last FXR models in regular production.

The FXDX Super Glide Sport was introduced in 1999, featuring improved suspension components and triple disc brakes. The FXDX-T Super Glide T-Sport, with a fork mounted fairing and improved detachable saddlebags, replaced the FXDS-Conv Dyna Convertible in 2001, and was discontinued in 2003.

The FXDC returned to the line in 2005 as the Super Glide Custom.

In 2006, a new Dyna chassis was introduced along with a new six-speed transmission. In the same year new models were the FXDBI Street Bob (a minimal, single seat Dyna Glide motorcycle available in the new 'denim' (matte) black color) and the limited edition FXDI35 35th Anniversary Super Glide (colored to resemble the original white 1971 Super Glide). The FXDX Super Glide Sport was discontinued.

In 2007, the Twin Cam 88 engine was replaced by the fuel-injected 1584 cc Twin Cam 96 engine across the entire Harley-Davidson Big Twin lineup, including the FXD series. The 'I' model designator was dropped for all models, since all Big Twins from then on had fuel injection.

The FXDF Fat Bob was introduced in 2008. In the same year, the FXDWG Wide Glide was offered as a limited edition 105th Anniversary model before being retired, re-emerging in 2010 with a different (bobber) rear treatment. 2010 also saw the discontinuation of the FXD base model (replaced by the FXDB) and the loss of the FXDL Low Rider. 2012 saw some Dynas obtain the TC103 engine, available in the FXDF and FXDWG models as well as the new FLD Switchback, a sport-tourer.
