BMW created the dual-sport motorcycle when it released the R80G/S in 1980. The concept started with a BMW engineer who modified an R75/5 to race in the brutal International Six Days Trial, an off-road motorcycle race. That led to the R80G/S, which quickly found success in the Paris-Dakar rally, winning in 1981, '83, and '84. The R80G/S Paris-Dakar was made for one year only, and around 200 were thought to be made. Many others were converted over the years — but this bike is an all-original example sold in the US. In addition to the unique front fairing, rear fender, and tank, the bike has twin Bing carbs feeding BMW's legendary type 247 797.5cc horizontal-twin engine and Monolever single-sided swingarm that uses a single rear shock and the driveshaft as part of the rear suspension. Showing only 5,593 miles, the bike is currently up for auction.
