1994 BMW R 1100 RS ABS, The R259 1,085 cc flat-twin engine had a maximum output of 90 horsepower (67 kW). The engine was named "Oilhead" as it had air-cooled cylinders but oil-cooled heads. The BMW R1100RS had a frameless design, using the engine as a stressed member, an approach used by BMW for all subsequent oilheads (except the R1100S). Instead of having conventional telescopic forks, the R1100RS used BMW's own Telelever suspension which bolted directly to the engine. The Telelever design has a superficially similar appearance to telescopic forks, but braking forces are taken back horizontally, minimising "fork dive". A rear subframe supported the rider, passenger and luggage. Both fully faired and half-faired variants were available.
