This 1974 BMW R90S looks great in Daytona Orange with R100RS fairings, and condition too appears to be quite good. The seller doesn’t provide a lot of detail, but appearances suggest that running condition should probably be just as good. Hard BMW OEM panniers and a high windshield should make this one a fine long-distance cruiser, too. Find it here on mobile.de in Etten-Leur, Netherlands for 7k Euros (-$7,450 USD today).
Daytona Orange is a striking, very period-style color, and along with RS fairings, windscreen, covered headlight, and ducktail seat, it makes for quite an interesting profile. Paint finish looks good all around, and trim and lenses show just as well. A tool roll resides under the seat along with extra room for accessories, and dual hard panniers up the storage capacity even more. These bikes came equipped with wire spoke wheels, but we dig the period snowflakes fitted here.
The cockpit is very clean, with good-looking plastics, grips, hardware, and instrument faces. The windscreen is also clear, as are mirrors. The knob mounted to the fork crown adjusts the hydraulic steering damper.
The photo below highlights the aero fairings, and shows them to be in good condition. Glossy paint is found everywhere, with no hints of cracking, rock chips, or other damage. Note the twin-disc front wheel that featured drilled rotors on the later models.
The air-cooled boxer displaces 898cc and was good for 67 HP off the factory floor. Backed by a 5-speed transmission, it routes twist through a shaft drive in traditional Beemer style. The odometer on this example reads 97k and change kilometers. Another improvement for these Series II bikes was the addition of a strengthened crankshaft and redesigned main bearing, which contributed to greater reliability.
We’re fans of sport tourers from the 70’s and 80’s, and this model is one of the most interesting examples we’ve seen recently. Provided it’s as sorted as appearances hint at, a machine like this could easily serve as a daily commuter, then load up for a quick weekend getaway when needed.
