[edit] 1971 FX Super Glide

From 1934 to 1970, with the exception of the Servi-Car, there have been two distinct lines of V-Twin Harley-Davidson motorcycles, the small twins and the big twins.^[2][3] However, individual bikers would sometimes customize bikes by changing parts around or cutting and rewelding frames and other components to suit their tastes.

Harley-Davidson styling director Willie G. Davidson was aware of this phenomenon and decided to design a motorcycle for production that would offer the look of the custom bikes. To accomplish this, he started with the frame and rear suspension (but not the electric starter) from the FLH Electra Glide, to which he then mated the smaller telescopic forks from the XLH Sportster. This combination was referred to as the FX chassis, to denote a FL frame with XL forks. The drivetrain and engine accessories were from the FLH, the front headlights and brakes were from the XLH. To complete the Super Glide, he added buckhorn handlebars and a "boattail" tail/fender unit similar to those being used on the XLH Sportster.^[1]

The production FX Super Glide was released in 1971 to a lukewarm reception. Particularly not well received was the "boattail", which also proved to be unpopular on the Sportsters that had it. Sales of both models improved when less radical rear styling was made available.^[3][4]

[edit] Variations of the FX Super Glide

In 1974, the FX was joined by the FXE, a version of the Super Glide with an electric starter. Both versions also got an exclusive one-piece tank instead of the Fat Bob tank used by the FL.^[3]

In 1977, the FXS Low Rider was introduced. The Low Rider had alloy wheels front and rear, two disc brakes on the front whel, extended forks with a 32° rake, and a 26" seat height. ^[5] Unlike the Super Glide, the Low Rider was an instant hit; outselling all other Harley-Davidson models in its first full year of production.^[6] All three FX models returned to using Fat Bob tanks, but with a special centre divider that included a tachometer.^[3]

The base, kickstart-only FX was discontinued in 1979. In that year, the FXEF Fat Bob was introduced.^[7]. The following year would bring the FXB Sturgis, an all-black Low Rider with primary and secondary belt drives, and the FXWG Wide Glide, a Low Rider with wide forks and a flame pattern painted on the tank.^[7]

In 1983, the Low Rider was converted from chain drive to belt drive and given the designation FXSB, at which point the FXB was discontinued. In the same year, the FXDG Disc Glide was introduced. This model had a disc-type rear wheel instead of the wire-spoked wheel of the Super Glide or the solid-spoked wheel of the Low Rider.^[7]

The FXE Super Glide was discontinued in 1985, with the FXEF Fat Bob becoming the base model.^[7]

In 1986, all FX-based bikes except the Wide Glide were supplanted by FXR-based bikes. The Wide Glide was discontinued the following year. ^[7]

[edit] FXR

The FXR Super Glide II was introduced in 1982 and sold alongside the existing FX models. The FXR chassis was essentially a FLT Tour Glide chassis with lighter frame tubes and a more conventional design around the steering head.^[7] As such, it offered a rubber-mounted engine and a five-speed transmission, as opposed to the solid mounting and four-speed transmission of the original FX chassis.^[7]

The FXR range was expanded in 1984 by the introduction of the FXRT Sport Glide, a Super Glide variant with a fairing and saddlebags, and the FXRS Low Glide, which was the FXR equivalent of the FXSB Low Rider. Upon the discontinuation of the corresponding FX-based models, the FXR Super Glide II became the FXR Super Glide and the FXRS Low Glide became the FXRS Low Rider. The Wide Glide was discontinued because the FXR frame was not suitable for the wide forks. ^[7]

[edit] Dyna

Design work began on the replacement for the FXR chassis shortly after the first FXR bikes were offered.^[7] The Dyna chassis was introduced in 1991 with a limited-production FXDB Sturgis model. The engine mounting system was more vibration-resistant than that of the FXR.^[8]

The Sturgis was followed in 1992 by the limited-edition FXDB Daytona and the regular-production FXDC Dyna Glide Custom.

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 FXRS-Conv Convertible and FXRS-SP Low Rider Sport the continued to be offered. The FXDWG Dyna Wide Glide was introduced in the same year. The Low Rider Sport was discontinued in 1994.^[7]

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 FXRS-Conv Low Rider Convertible, which were the last FXR models in regular production.^[7]

The FXD Super Glide, the FXDL Low Rider, and the FXDWG Wide Glide have been in production ever since. 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 Congertible in 2001, and was discontinued in 2004.^[7][9]

The FXDC Super Glide Custom returned to the line in 2005.^[10]

In 2006, a new Dyna chassis was introduced.^[11] In the same year, the base FXDI Super Glide became a single-seat motorcycle, the FXDBI Street Bob, a minimal, single seat Dyna Glide motorcycle was added to the lineup, the limited edition FXDI35 35th Anniversary Super Glide was offered, and the FXDX Super Glide Sport was discontinued.^[11][12]
