Production history[edit]
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.[citation needed]
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.[citation needed]
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.
58,023 units of standard R1150GS model were produced, while 17,828 units of the Adventure models were produced.[
