The seller of this beautiful R25 has “traced its lineage/owners back as far as 1968,” noting that he’s got a “reasonably accurate history, down to the Swiss ammo pouch that belonged to Dieter Drews who mounted it on the luggage rack circa 1983, exactly where it resides to this day.”
The history of this bike is more interesting to me than the general specs of the R25 single, but if you want to know more about the ~12 horsepower, 350 pound machine, check out this retrospective on Rider.
Per the seller, this R25 was in Germany until 2009, though it’s not clear if he was the one who imported it to the US or not. Either way, he’s aware of a “catastrophic engine failure” in the late 60s, after which the motor was swapped for a ’55 R25/3 unit. That replacement motor has since been rebuilt twice – 2011 was the last time. The sale includes English and German versions of the owner’s manual and service manual as well as a “large box of parts and memorabilia, including every rubber bit on the bike, powdered and sealed in a large glass jar.” It’s mechanically refreshed but the cosmetics are highly original, which I personally adore.
