Post-Listing Update: Despite 20 bids on eBay topping out at $72,655, this DKW SS 250 failed to meet reserve.

One of the most famous reverse-cylinder motorcycles of all time, the DKW SS 250 featured a “split-single” or “twingle” engine which had two pistons driven by a split con-rod. DKW used this technology in several bikes up to 500cc, but none might be as cool as this model, sold as a production racer supposedly offered at a loss. In 1938, the chassis was upgraded and all privateer bikes were distinguished from the factory race bikes with the black/red paint scheme.

The engine of this motorcycle (which was supercharged) is fascinating, and above my technical knowledge. All I can tell you with confidence is that by ’38, DKW rated the engine at 35 horsepower @ 7k rpm, which was good for a top speed of 110 mph.

This specific DKW SS 250 (VIN: 429365) was restored after the current seller bought in the 80s. It was then run (but not raced) at several AHRMA events, where other riders claimed it was so loud that they “experienced regular shock waves coming from the exhaust.”
