BMW R1150GS

The BMW R1150GS and R1150GS Adventure are motorcycles that were manufactured by BMW Motorrad between 1999 and 2005. The R1150GS models are part of the BMW GS family of dual-sport adventure motorcycles that have been produced from 1981 to the present date. The bikes have a 1,130 cc horizontally opposed flat-twin engine and shaft drive.

Production history

The 1,130 cc R1150GS had a new six-speed gearbox. It replaced the R1100GS, which had a 1,085 cc engine and a five speed gearbox.

The standard R1150GS model was produced from 1999 to 2004, when it was replaced by the more powerful and lighter R1200GS. The Adventure, which was produced from 2001 to 2005, was replaced by the R1200GS Adventure in 2006.

In late 2002, the optional ABS system was replaced with an electrically servo-assisted combined braking system. In addition the engines were equipped with twin spark plugs on each cylinder to improve emissions and improve a persistent surging problem that affected many BMW boxer models.
