An old-school R 100 GS is synonymous with rock-solid dependability and German engineering prowess.
The 1991 BMW R 100 GS is put in motion by an air-cooled 980cc boxer-twin power source, with four valves, dual Bing carbs, and a compression ratio of 8.5:1. When prompted, the mill can spawn as much as 60 hp at 6,500 revs per minute, along with 56 pound-feet (76 Nm) of torque lower down the rpm range.
A five-speed transmission sends the engine’s oomph to the rear 17-inch wheel by means of a shaft final drive, resulting in speeds of up to 112 mph (181 kph). The Beemer’s powertrain is enveloped in a double cradle skeleton, whose front end sits on 40 mm (1.6 inches) Marzocchi forks.
On the other hand, rear suspension duties are managed by a preload-adjustable monoshock that’s mated to a Paralever construction. This setup provides 225 mm (8.9 inches) of wheel travel up north and 180 mm (7.1 inches) at the opposite pole. As far as braking duties are concerned, the front hoop is brought to a halt by a single 285 mm (11.2 inches) rotor and a twin-piston Brembo caliper.
Down south, you will find a simplex drum brake with a diameter of 200 mm (7.9 inches). Bavaria’s dual-sport beast houses a fuel capacity of no less than 6.3 gallons (24 liters), while its curb weight is rated at 462 pounds (210 kg). Right, we’ve now covered pretty much all of the essentials, so it’s time to cut to the chase.
This article’s photo gallery presents a tidy ‘91 MY R 100 GS that features new fork seals, youthful spark plugs, and a pair of Enduro 3 Sahara tires from Metzeler’s inventory. A few months ago, the bike also received a premium battery and fresh fluids to keep things running smoothly.
As you’re reading this, the German wonder is going under the hammer at no reserve on Bring A Trailer, where you may place your bids until Monday, December 20. For now, you could get away with spending a little over six grand on this machine, which is nothing less than a genuine bargain.
