BMW R 80GS (1988)

The BMW R 80GS is a testament to the German marque’s commitment to producing rugged, dependable motorcycles that can conquer the toughest off-road terrain. This revamped bike boasts a new rear suspension, the Paralever, which replaces the monolever, and a name change that reflects its newfound focus on Sport.

The engine is where the R 80GS truly comes alive, with a 798cc, air-cooled, two-cylinder unit producing 50 horsepower at 6,500 rpm and 61 Nm of torque at 3,750 rpm. The ride is characterized by a smooth, predictable feel, with the Paralever suspension soaking up bumps and irregularities with ease.

Whether you’re carving through twisties or tackling the toughest off-road trails, the R 80GS is the perfect companion. Its lightweight chassis and 210kg curb weight make it agile and responsive, while the 24-liter fuel tank and tool box under the seat ensure you’re always prepared for the long haul. With its robust engine, capable suspension, and rugged styling, the BMW R 80GS is the ultimate adventure machine, ready to take you wherever the road – or trail – may lead.
