It could reach a top speed of 181 km/h / 112 mph.  

==Engine==
The engine was a Air cooled cooled Four stroke, two cylinder horizontally opposed Boxer, 2 valves per cylinder. The engine featured a 8.5:1 [[compression ratio]].  

==Drive==
Power was moderated via the Dry single plate, with [[diaphragm]] spring.  

==Chassis==
It came with a 90/90-21 front [[tire]] and a 130/80-17 rear tire. Stopping was achieved via Single ∅285mm disc, 2 piston caliper in the front and a ∅200 Drum in the rear. The front suspension was a  Telescopic fork with hydraulic shock absorber. while the rear was equipped with a Paralever adjustable preload, rebound damping compression. The R100GS Bumble Bee was fitted with a 24 L / 6.3 US gal fuel tank. The wheelbase was 1514 mm / 59.6 in long.

== Overview ==
BMW R 100GS
Bumble Bee























The R100GS is one of the world's biggest and fastest off-road bikes. It is
very good on the road but not so good on the dirt. The GS stands for
Gelandestrasse or street scrambler. BMW call it 'a hobby bike, a two-wheeled
Range Rover' and the comparison is appropriate. It is not a serious dirt bike
but it is one of the best all-purpose bikes ever built. Suitably beefed-up
factory versions have won the gruelling Paris to Dakar rally on three occasions.
In stock production form, the 100GS has proved a popular choice for riders
exploring the world on long distance trips across continents with all types of
terrain. It is a 115mph road bike that can cope with the rough stuff. The
machine is an imaginative mix of parts that were already available on other BMW
bikes, spiced with some adventurous engineering. An example is BMW's patented
Paralever rear suspension, a one sided swing-arm with a single gas shock unit.
In effect, it is half a swing-arm, but BMW's engineers made it both lighter and
50 per cent stronger than a conventional assembly. The rear wheel is held on by
three bolts, there is nothing you could call an axle. The wheel bearing is big,
the crown wheel housing is internally stressed since it has to carry the full
loads of the back wheel with 7in of travel available. The Paralever rear
suspension works admirably, eliminating driveshaft torque reaction. Quick wheel
changing is obviously a bonus.



The front suspension consists of leading axle forks offering a
luxurious 8.8in of travel. The bike is tall and needs to be for reasonable
ground clearance (8.58in). The steering is quick and the throttle response
lively. The whole machine is light and nimble with plenty of power and very good
brakes. Like all flat twin BMWs, it has a low centre of gravity, so the bike can
be chucked around with abandon. The dual-purpose, knobbly tires are high-speed
rated and tubeless thanks to an innovative cross-spoke wire wheel and isolated
rim design. The engine is an updated variant of the R80 road bike endowed with
typical BMW performance - bags of torque and a wide spread of power  plus some
dual-purpose innovations. The bike has a lightweight clutch and flywheel for
quicker throttle response, and low gearing; necessary for a dirt bike but lots
of fun anywhere since it helps the GS to wheelie easily. On the open road it
will hold 1 lOmph for as long as the rider can face sitting up so high and
exposed against the wind. Unfortunately what makes it good on the tarmac tells
against it on the dirt. The bike is just too big and too powerful. Fully gassed
(5.7gal) it weighs 4541b, fine for a road bike but a little heavy for serious
off-road use. In addition there is the long wheelbase, the unsprung weight of
the driveshaft and two horizontal cylinders that stick out a long way, all
factors that conspire against its dirt ability. These are not problems when
traction is positive on firm ground but in mud and real rough stuff, the bike
bogs down far too easily.
The R100GS is best used as a cross-country bike, sticking mainly
to proper roads but taking the odd short cut and back road where necessary.
Above all else, the bike is a lot of fun to ride; it is a functional, practical,
rugged and reliable all-rounder. Recently, various BMW importers have released
Paris-Dakar replica versions of the bike as a tribute to one of the world's most
successful desert racers.
