Teutonic Trackday Terror: 1973 BMW R-Series Endurance Racer for Sale

1973 BMW R-Series Endurance Racer L Front

BMW’s boxer twins have long been associated with old men, heated grips, and hard luggage. But there have been racing Beemers as long as there have been Beemers and the quirky, shaft-drive “air-head” bikes are durable and can be extremely quick when properly prepared. This particular R-Series bike includes a veritable who’s-who of German race and top-shelf performance parts, with Silent Hektik twin-plug points-less electronic ignition [they also do Guzzis!], a Werner Fallert deep oil sump, restoration work by Hinrich Hinck, and uprated Lockheed brakes to replace the reportedly unimpressive stock front stoppers.

The original listing also mentions Gus Kuhn, whose name is proudly displayed on the side of the bare-metal tank. Gus Kuhn was a British racer, tuner, and dealer during the 1950s and 1960s. Although he died in 1966, Gus Kuhn Motors successfully raced Nortons and BMWs, eventually becoming one of the top BMW dealers in the world. It’s not clear from the listing if this is an actual Gus Kuhn machine or one simply intended as a tribute.

From the original eBay listing: 1973 BMW R-Series Endurance Racer for Sale

Gus Kuhn Endurance, Marzocchi Lockheed GP Kroeber, Silent Hektik ignition, short piston engine overhauled

We have bought this Endurance Racer in Great Britain. Together with our friend Hinrich Hinck we decided to restore this very nice classic racer. We wanted to get as possible a high degree of originality. But we also wanted to build a very good racing machine and together with the experienced Hinrich Hinck we have done it.

The result: engine overhauled by BMW engine specialist Israel with short piston, Fallert oil pan,  Lockheed GP brakes, Marzocchi front fork, 18 inch rim, Kröber rev counter, aluminium fuel tank, Silent Hektik ignition, double spark,

Now it is ready to race for classic events.

Please note that the bike currently resides in Germany but, since it’s in no way road-legal, at least there’s no question as to whether or not it can be registered here in the US. There’s plenty of time left on the listing, with six days still to go, and bidding has not hit the reserve. At just over $3,000 that’s no surprise. Given the components, preparation, and that gorgeous bare-aluminum tank, this should be worth double that figure, assuming the right eclectic buyer can be found.
