Originally named the Sachs 125, the DKW 125 Enduro earned its titled after DKW and Sachs merged in the 60s. It ended up becoming one of the first baby MX bikes that took off in the US, as it compared well against the Kawasaki Green Streak and Hodaka Ace. It was a reliable package (though the Sachs unit apparently yielded a few too many false neutrals), and the whole package could be yours at the time for $748.
A decade later, the Sachs-powered model had been usurped by more modern competition. Still, for a few years the combination of a 125cc motor, leading-link forks, and Boge shocks was satisfying for American riders. For more on this model, check out this profile from Motocross Action Magazine, who call it Classic Motocross Iron.
