Welcome to On The Lift sponsored by Clymer Manuals

Today we have a 1983 BMW R80RT R80 RT R 80 RT R 80RT on the lift. Following BMWs long held tradition; this is an evolution of the same boxer twin released in 1970 for the slash 5 ( /5 ) models.

======= Check out On The Lift 1970 BMW R75/5 =========

While featuring many changes over 20 plus years, this bike still bears the strong family traits of its predecessors.

In 1979 BMW introduced the first production motorcycle with an integral non-optional touring fairing. Working with the RS design, which featured cutting edge, for the day, wind tunnel testing, BMW made the fairing larger and added a tall screen for the RT. Today this fairing seems, well commonplace, but back then no other manufacturer was close to releasing such a model. The Honda GL1100 Gold Wing ( Goldwing ) Aspencade wouldnt be available from Honda until 1982. Of course you could purchase a number of bolt of fairings ( Vetter ), but these hardly featured the design standards set by BMW.

In 82 BMW offered the budget model version of the liter machine as the R80RT.

======== Suggested retail for an R80RT was $5490. The R80RT was $1400 less the 1000cc RT. This price did not include the optional hard bags. ========

======== The R80RT was available in two colors: Metallic Pacific Blue with silver trim and Metallic Red with gold trim. ==========

To compensate for the smaller displacement engine the R80 has a lower rear differential ratio by about 15%. In addition, the clock and voltmeter are not in the fairing; instead a couple of plugs cover the openings. Even with the higher revs, the 6.2 gal tank gives a range of roughly 230 miles at 45 mile per gallon.

======== A 1985 models tested out at 57 high / 45 low / 49 ave. mpg ====

The bike features a 5-speed transmission mated to the tried and true swing arm/driveshaft design. By this point a number of modifications were accomplished to the shift mechanism to prevent false neutrals and long gone is the kickstarter of the original /5 models.

The front brakes are Brembo twin calipers, unlike the R100, which has a rear disc, the R80 uses a drum. The drum works well and rear wheel removal is certainly simplified over the disc model.

Here you see one of my aftermarket add ons A Browns sidestand. This thing is a huge improvement over the original. Now that will certainly get some argument, but seriously, who can logically say the BMW sidestand is a good design. Personally Ive replaced that thing on every airhead Ive owned and will do so in the future.

The rear swingarm/drive shaft uses a twin shocks. In 1985 the R80RT rear suspension adopted the single shock Monolever design.

Along with the soft front suspension, these two areas are the most common upgrades. This bike is riding on its original front and rear suspension components and is slotted for a pair of progressive springs and new rears shocks, which will be a big improvement.

In the day, this bike was reviewed pretty harshly. Pretty unfairly really. Comparing this bike, with its controllable and predictable power and handling, to the late 70s/early 80s 750s wasnt applicable. And the comparison to the liter plus touring machines was also off. Really, as BMW often does, this was one the first sport-touring machines and ahead of its time.
