BMW R 850 GS: boxer engine, features and what to check on a used one
BMW R 850 GS — the simpler, more affordable sibling of the R 1100 GS, produced from 1998–2000 with an 850 cm³ boxer engine. We look at what sets it apart and what to check when buying a motorcycle of this age.
R 850 GS in brief
The R 850 GS is a touring enduro motorcycle with BMW's well-known boxer (opposite-cylinder) engine. It's built on the R 1100 GS platform but with a smaller, 850 cm³ capacity and slightly less power.
This isn't cutting-edge tech, so buyers usually look for reliability, robustness, and easy maintenance for long journeys. For many, it's the quintessential 'old school' GS.
Which generation is this?
The R 850 GS was produced briefly — from 1998 to around 2000 — and essentially represents a single generation. It belongs to the so-called 'oilhead' generation, where cylinders are cooled by both air and oil.
It was later replaced by the R 1150 GS with a larger engine capacity. Due to its short production run, the R 850 GS is relatively rare in the used market, so prices depend on condition and collectability.
Engine and gearbox
The engine is a twin-cylinder boxer, around 850 cm³. It's known for smooth operation and excellent low-rev torque, and maintenance is straightforward as the cylinders and heads are easily accessible.
Power is transmitted to the rear wheel via a cardan shaft, so there's no need to worry about a chain. Up front, it uses BMW's Telelever suspension, and at the rear, the Paralever system.
What to check when buying a used R 850 GS
Check the oil leaks around the engine, cardan drive, and final drive. Ask when the oil was last changed in the gearbox and final drive.
Inspect the Telelever and Paralever suspension, linkages, brakes (and ABS system if present), electrical wiring, and signs of corrosion on the tank and frame. Due to the motorcycle's age, the service history and how many years it stood unused are particularly important.
