In 1994, BMW presented the first Enduro with a four-valve Boxer engine. In common with the two forerunner generations, the BMW R 1100 GS once again defined benchmarks. When the motorcycle was launched, it was the fastest Enduro on the market with the biggest capacity and greatest power output. Additionally, the machine was the only Enduro offering a fully-controlled three-way catalytic converter and ABS (capable of being deactivated in off-road situations). Like its predecessors, the R 1100 GS provided the perfectly balanced synthesis of off-road and touring motorcycle. High sales volumes for the twin-valve GS were again eclipsed by the R 1100 GS.
