In 1983, BMW debuted the all-new K 100. The K stood for Kompaktes Antriebssystem, the Compact Drive System for multi-cylinder engines that borrowed their aluminum/Nikasil block, five-bearing crank, connecting rods, dual overhead cams, Bosch LE Jetronic fuel injection and transistorized ignition from BMW’s car engines. The engines mounted longitudinally in a load-bearing frame with Monolever rear suspension, cast aluminum wheels, and triple disc brakes. A young Chris Lordan read about the K-bikes in Car and Driver in 1984 but didn’t get his own until 2018. “My only regret is the eternal one: I never should have waited so long!” he says.
