📚 Vehicle History

Bmw Motorrad Legacy:

BMW Motorrad has a long history of producing robust, reliable motorcycles, particularly known for their boxer engines and shaft drive systems since the 1920s.

Gs Lineage:

The 'GS' (Gelände/Straße - Terrain/Street) designation signifies BMW's successful dual-sport and adventure touring motorcycle line, originating with the R80G/S in 1980.

R80Gs Introduction:

The R80GS was introduced in 1987, evolving from the R80G/S, offering more travel and off-road capability.

R100Gs Introduction:

The R100GS was introduced in 1987 as the larger displacement sibling, offering increased power and torque for touring and carrying loads.

Paralever Evolution:

While this 1995 manual is for the R80/R100 GS, it's worth noting that later GS models (from 1987 onwards, and evolving significantly by the mid-90s) featured the innovative Paralever single-sided swingarm system, improving rear suspension performance and drive shaft geometry.

Manufacturing Era:

The R80GS and R100GS models were produced from 1987 through the mid-1990s (with the last of the R100GS models being sold around 1996).

🏆 Awards & Recognition

Legacy Status:

Widely regarded as an iconic and highly capable adventure motorcycle, forming the basis of BMW's enduring GS legacy.
