== Overview ==

BMW R 100GS Paris Dakar


















In the 1980, BMW began an unlikely assosiation
with the Paris Dakar Rally. At that time, the then 2 year old rally had been
dominated by some rather uncommon machines: hand prepared BMW Airhead boxers.
The demands of the Sahara were too great for the average dirt bike of the time.
What was needed to win was a stone reliable machine with great range. To answer
that question, teams prepared motorcycles that were largely stock, right down to
their factory Bing or Dellorto carburetors. Yes, they ran more efficient air
cleaners and open exhausts but power does not win Dakar, reliability and
consistent performance does. The frames were reinforced, swingarms were
lengthened and long travel shocks installed. The best forks and brakes of the
day were pulled from KTM motocross bikes and installed on the BMW desert sleds.
To finish the machine off, huge fuel tanks were fitted. Some of these hand
hammered aluminum tanks held more than 11 gallons (US) of fuel. Of course the
well known BMW shaft drive was largely impervious to the 5000+ miles of sand
each machine would face. Yes, it was heavy but it was stone reliable and easy to
maintain and that's what it took to win Dakar. Gaston Rahier and others rode
these beasts to win after win. Yes, other bikes were faster or lighter but in
the end, the reliability and the comfortable pace maintained by the BMW's
eventually dominated.

BMW Accidentally Creates a New Genre of Motorcycling

To celebrate this achievement, BMW built Paris Dakar commemoritave bikes
beginning in 1981. Labled the BMW R80GS, the bike featured white paint and a
color scheme strangely reminescent of the rally bikes. It was basically a
doctored R80 with longer travel suspension and high fenders. It also featured an
uncommon feature for the day: a single sided swingarm. Labled the "MonoLever" it
housed the ring & pinion in the right side of the swingarm. On the opposite side
of the wheel, three lug bolts secured the wheel to the ring gear. The GS didn't
really offer more fuel capacity or serious off-road capability but just as the
1975 GL1000 Gold Wing accidentally became the touring standard, the little GS
invented a new segment of the market previously ignored: Adventure Touring.
Imagine touring for days on paved roads, only to see a gravel road meanering off
into the mountains--a gravel road you don't dare take your plastic wrapped
touring barge onto. That's the market the R80GS was destined to dominate.




The BMW R80 GS enjoyed a small but rabidly enthusiastic and growing market. It
continued largely unaltered from 1981 through 1987. In 1988, the machine
recieved its first major revamp becoming the R100GS. We have a "Bumblebeemer"
example of the 1988 model year here. The 1988 upgrade included a displacement
bump from 800 to a full 1000cc's. The 800cc displacement was still available
outside the United States albeit, with the newer chassis and styling. The new
bike featured longer travel, stiffer front forks and another upgrade to the rear
suspension, becoming the Paralever. This new system floated the ring & pinion
housing with a torque arm, virtually eliminating the characteristic shaft drive
pogo-effect while transitioning the throttle. This bike inched closer still to
the BMW rally bikes that had also enjoyed continued success over in Africa.

1990 was to see the introduction of an official "Paris Dakar" conversion kit.
This kit included a 9.0 gallon nylon fuel tank, a steel 'roo-bar' around a new
fixed headlight assembly and instrument cluster with tachometer. Underneath,
larger, vented skid plates attached to both the engine and the centerstand. A
plastic fender extension--looking every bit like a childs sand shovel--added
length to the front fender. Later in 1990, BMW began offering the 'kit' on
factory motorcycles and labled it the R100GS/Paris Dakar. The factory bikes also
included the factory BMW hard bags as standard equpment, as well as heated
grips.

I vividly remember reading Bill Stermer's article in 1990 reviewing the new
machine, as well as Clement Salvadori's awesome trip through Engineer Pass in
Colorado. You didn't have to be a fan of the Paris Dakar Rally to see why this
bike was so alluring. With its plush, long travel suspension, honest 300 mile
range (before you start LOOKING for gas) and factory hard luggage, the big boxer
quickly became a favorite among street-going BMW fanatics. Never mind taking it
off road, this was a GREAT road bike. It quickly became one of BMW's best
selling models and to this day, it is often argued to be the very best
all-around Airhead BMW ever made. In later years, the Paris Dakar name had to be
dropped due to licensing issues with the rally organizers so it was simply
shortened to PD.
