No, the BMW R1150GS is not fuel injected. It utilizes a fuel delivery system known as a fuel injection system, which is a combination of electronic fuel injection (EFI) and intake manifold injection. This system uses electronic controls to precisely meter the fuel and inject it into the intake manifold for combustion.
The R1150GS model, produced from 1999 to 2004, features a 1,130 cc air/oil-cooled boxer engine. It uses a system called Motronic, which is BMW's electronic engine management system. The Motronic system on the R1150GS includes an electronic fuel injection system that works in conjunction with other engine control functions.
While the R1150GS has electronic fuel injection, it is important to note that newer models in the BMW GS lineup, such as the R1250GS, have advanced further in terms of engine technology and may incorporate additional features and improvements.
