Vehicle Information
BMW R100CS Motorcycle - Street (1980-1984)
The BMW R100CS, produced from 1980 to 1984, was a distinguished model in BMW's "Airhead" series, celebrated for its unique blend of sportiness and comfort. This motorcycle was consistently powered by an air-cooled, four-stroke, boxer two-cylinder engine with a 980 cc displacement, delivering a steady 70 horsepower (51 kW) at 7,000 rpm across all model years. While the R100CS itself was a specific trim introduced in 1981, significant updates occurred during its production. For the 1981 model year, the engine received new all-aluminum cylinders with a nickel/silicone-carbide coating, improving heat conductivity and reducing oil consumption. The flywheel, transmission input shaft, and ignition system were also updated, with compression reduced and electronic ignition introduced. From 1980, front brakes were upgraded to Brembo fixed calipers. The 1984 model year marked the "Last Edition," a commemorative version featuring specific Pearl White paint with Motorsport pinstripes and "Last Edition" graphics, often equipped with saddlebags.
