Summary
From Bring a Trailer
This BMW motorcycle was the subject of a build completed in 2020 by Boxerworks of Watkinsville, Georgia, that involved powder-coating the frame, fitting a Ural sidecar and an Earles fork, refinishing the rig in cream and black, and installing a 980cc opposed twin and five-speed transmission sourced from a BMW R100GS. The headlight, instrumentation pod, and wiring harness were sourced from a /5 model, and additional equipment includes a driveshaft, a stainless-steel two-into-two exhaust system, a Denfeld solo saddle, a rear parcel rack, and Hella bar-end turn signals. The Ural sidecar features chrome lighting components, a locking trunk, a folding windscreen, black leather seating surfaces, and a spare tire mounted under a luggage rack.
More details
The rig was previously listed on BaT in November 2023, and it was acquired by the seller in 2024. This BMW sidecar rig is offered with a conditional Georgia title in the seller’s name. The fuel tank and fenders were refinished in cream and black with cream pinstripes as part of the 2020 build.
Further work at the time involved powder-coating the frame and related components in black and internally sealing the fuel tank. Features include a black Denfeld solo saddle, a chrome-rimmed headlight sourced from a /5 model, and a cargo rack on the rear fender. Wire-spoke 18″ wheels are laced to polished drum-brake hubs and are mounted with Metzeler tires.
The Earles fork is fitted with a pair of enclosed shocks up front, while a pair of adjustable enclosed shocks is attached to the swingarm on the left and final drive housing on the right. The wheel bearings were replaced as part of the 2020 build along with the bearings and seals on the steering stem, fork linkage, and swingarm. The Ural sidecar was refinished in a coordinating cream and black paint scheme and installed via adjustable crossbars as part of the 2020 build.
Sidecar features include a black tonneau cover, a headlight, a chrome guard, chrome turn signals, a spare tire secured below a black luggage rack, and a locking trunk. Passengers enter using the equipped side step and are provided with a lap belt, a grab bar, seating surfaces upholstered in black, and wind protection via the folding clear windscreen. The sidecar is further equipped with a drum brake, a 19″ wire-spoke wheel with a Dunlop tire, and a single shock.
The chrome cross-braced handlebar fronts a 120-mph speedometer and a pair of indicator lights (*please confirm). The five-digit odometer shows 34237 miles, approximately 70 of which were ridden under current ownership. Total mileage is unknown.
The R100GS-sourced 980cc OHV opposed twin was installed in 2020 and utilizes a wiring harness sourced from a /5 model. The engine breathes through a pair of Bing carburetors and a replacement stainless-steel exhaust system. Power is sent to the rear wheel through an R100GS five-speed transmission mated to the existing R50S driveshaft.
The final drive reportedly employs a 27:8 ratio. The frame is stamped with the number 564276, which is consistent with a BMW R50S produced for the 1960 through 1962 model years. The Georgia title describes the bike as a 1959 BMW R100, and it carries a notation reading “Conditional title — May not reflect all liens or other encumbrances.
