The F650CS was a standard motorcycle made by BMW Motorrad from 2001 to 2005. CS stood for city/street, as it was aimed at urban commuters and it was also known as the Scarver, a portmanteau of street and carver. The CS was the third generation in the F650 single series, after the 1993–2001 F650, and 2000–7 F650GS. It was known for its offbeat styling intended to attract new motorcyclists.

The F650CS was designed by American David Robb, currently Vice President of BMW Motorrad Design, and designer of the R1100RT, K1200RS, R1200C, R1100S and K1200LT. The bike was the result of a partnership between BMW and Aprilia.

Many elements of the design, such as the striking colors used for the coordinated body panels, the Space Age instrument panel, translucent passenger grab handles, and slickly serviceable storage compartment had a consumer appliance feel and appearance, "remind[ing] you of current computer peripherals such as HP ScanJet printers." Its small transparent wind screen seemed "iMac-inspired", and the use of translucent polycarbonate elsewhere hinted at Apple's style at the time. The addition of superfluous oblong slots with incongruous rubber inserts along the sides of the aluminum frame led Rider magazine to quip that it was "overstyled". BMW "ripped a page from the strategy book of Apple Computer Inc" with its three "youth-oriented" color choices, azure blue metallic, golden orange metallic and beluga blue.
