Questa è la storia del GS1100: spero che te la cavi con l'inglese...
Model History
BMW slowly evolves models during their life, the R11GS is no exception. Some of the major changes are listed by model year.(1)
The first bikes
appeared at the beginning of 1994 available in:
Marakesh red Avus black Alpine white
and had yellow seats (with black as an optional alternative).
There is also a no cost black option - black front wishbone and engine covers. The red model has the black option, the others do not. Look under the tank for the black suspension strut and black engine (except cylinders). The picture of a 97 model offroad (by coincidence also red) shows the black option.
Changes during model year 94
lower black front mudguard extended
new cylinder head gasket (to stop leaks)
smaller cut-down bash plate
some changes to the oil system (supposedly to make oil run back to sump faster when the engine is turned off so checking oil level is easier)
new maintenance-free poly V (alternator) belt with increased service life
after VIN number 311168 improved transmission fitted
recall to fix problems found when riding offroad aggressively:
Apply a stronger adhesive to the right-hand bearing pin in the swingarm
Replace the lower flange nut on the front strut with one that self-tightens
Changes during model year 95
front suspension geometry revised; wheelbase increased 10mm (to stop ABS cutting in early)
original Akront chrome plated wheels changed to polished (but not lacquered) aluminum made by another supplier
low friction throttle cable with smoother action (especially at small openings)
Changes during model year 96
Marakesh red Avus black Kalahari yellow
white color bikes replaced by Kalahari yellow
original white/yellow tank decals replaced by black on red and yellow color tank and red on black color tanks
seat color changed from yellow to black with black color bikes having red seats (with option of black)
plastic fuel tank replaced by metal due to problems with mountings and tank decals. Shape and size slightly altered (official capacity down from 25 to 24 liters)
rear subframe attached to gearbox and its bolts beefed up (supposedly to stop frame breaking in extreme off road conditions)
quieter 80db exhaust
inlet and exhaust valves reduced by 2mm and stems by 1mm (to reduce surging or increase low end grunt?). No change in published performance specs.
Changes during model year 97
revised gearbox
simplified throttle and choke cable arrangement (only two cables connected to throttle body)
final drive housing breather bore increased
Also a new oil control valve installed from black engine number 41956271 and silver engine number 41959303. It was an attempt to make oil level more consistent but at best only a partial success. Best advice to put on sidestand immediately after engine switch off and leave overnight before checking still applies to all R11GS models.
Changes during model year 98
revised tank decals
new sidestand with larger foot
improved sidestand switch
aluminum wheels are now anodized
revised piston design - to reduce oil consumption
1998: The 75th anniversary edition
To mark the 75th anniversary of the first BMW bike, the R32, limited editions are available of all oilheads.
As you can see from the picture, (click on it to see a bigger version) the R11GS 75th Anniversary model is Marakesh red with Alpine white stripes. Included in the price were:
ABS
Heated handlebar grips
Bags rack
a "sumptuous" Anniversary folder containing:
an authenticity certificate
a valuable photo album of the BMW bike story (with pictures of the Anniversary-model and a place for a photo of the owner's actual bike)
a leather key-holder
a "75 years" pin
Changes during model year 99
R850GS launched. Very few changes in official specifications from the R11GS.
In Europe colors - red, black and Kalahari yellow.
In US, Kalahari yellow replaced by white (as image on left).
Final limited production two tone paint job available at extra cost - silver metallic/Dakar yellow (as image on left).
New tank decals.
Gearbox revised (again).
ABS II updated to reduce initialization problems especially in cold weather.
Front right brake caliper fitted with black allen headed bleed nipple. (It is part of the pressure bleed system used at the factory to pressure fill the brake system from the bottom. Dealers are supposed to remove it and install the standard bleeder. If not, see your dealer.)
In August 1999 the final R11GS rolled off the production line in Spandau, Berlin. It had been the most successful model of the GS models with 39,104 examples produced since September 1993. The R850GS continued unchanged.
