BMW R100 CS (1981-1982) Specs, Performance & Photos

The BMW R100, also known as the Slash 7 "Airhead," was a motorcycle made by BMW for 20 years from 1976 to 1996. The bike was powered by a 980cc four-stroke two-cylinder boxer engine and was completed in several versions.

In addition, the bike was the base model for many similar models with different visual and technical specifications and designations, such as T, S, CS, RS, RS Classic, RT, RT Classic, TIC, TC, R, and GS.

In 1981, the German motorcycle maker released the BMW R100 CS, a sportier and more comfortable version of the standard R100 model, created by the House of Munich alongside other derived versions.

The bike's aesthetic department was characterized by standard fittings, like a front cowl with a round headlight, a windscreen, a two-up seat with pillion grab handles, side-mounted rear shocks, a dual chromed exhaust system, and multi-spoke aluminum wheels.

On the front, the bike packed a telescopic fork that guided the front wheel, fitted with two 260 mm brake discs. The rear wheel was softened by side-mounted adjustable shocks and stopped by a 200 mm drum braking unit.

The 1981 BMW R100 CS had its soul brought to life by a 980cc four-stroke air-cooled twin-cylinder boxer engine mounted underneath the fuel tank, delivering an output power of 70 hp at 7,000 rpm and 76 Nm (56 lb-ft) torque at 6,000 rpm.
