The BMW R100 was a naked motorcycle manufactured by BMW since 1976 as a replacement model for the BMW/6 and produced until 1996 when it was replaced by the BMW K Series, also known as "Oilhead."

In addition to the standard R100 model, the manufacturer released several similar models with different designations, such as T, S, CS, RS, RS Classic, RT, RT Classic, TIC, TC, R, and GS.

In 1981, the German motorcycle manufacturer released the BMW R100, a motorcycle in its sixth consecutive production year, featuring the same specifications as previous models without any significant changes.

The bike's visual department was characterized by standard features, such as a round headlight with analog instruments mounted on top, a one-piece dual seat with a passenger grab rail, a luggage rack, side-mounted rear shocks, a dual exhaust system with a silencer mounted on each side, a center stand, and multi-spoke aluminum wheels.

The bike was built around a steel frame with a telescopic fork handling the front suspension and a 260 mm brake disc in charge of the stopping power. The rear end was controlled by dual adjustable shocks and a 200 mm drum braking unit.

As for the power figures, the 1981 BMW R100 boasted 67 hp with a peak force at 7,000 rpm and 72 Nm (53 lb-ft) torque at 5,500 rpm coming from a 980cc four-stroke air-cooled twin-cylinder boxer engine with two Bing carburetors in charge.
