Factory NSU Car Power: 1971 Münch Mammut 1200 TTS

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1971 Münch Mammut (Mammoth) is one of 478 NSU Prinz-engined bikes built, around 220 of which are known to remain. Built to order around the small German car’s lightweight, air-cooled, rear-mounted OHC four cylinder, no two Mammuts are exactly alike, and this one is particularly interesting for its use of an 85-horse 1200cc version–most came fitted with 1000cc units making about 30 hp less. Despite their physical size and gawky (but endearing) looks, these bikes weighed a reasonable-for-the-day 485 pounds, and in 1200 spec were capable of hitting 100 mph in around 10 seconds. Handling was decent as well, thanks to a Norton-style frame, and reflecting their high price and exclusivity, Mammuts were packed full of interesting features like an oil bath chain case that doubles as the swingarm’s left half. This one looks great, and is described by the seller as being in “near new and pristine condition.” Find it here on Gallery Aaldering in Brummen, Netherlands for 157,500 euros (~$183k USD today). Special thanks to BaT reader Kyle K. for this submission. Described in the ad as a “Kraftfahrzeugmechaniker” or motor mechanic, Friedrich Münch was born in 1927, served as a technician in the Luftwaffe, and in 1948 opened a Horex motorcycle shop. He then designed a series of bikes utilizing Horex parts, but when a friend introduced Münch to the NSU Prinz’s engine, development turned towards the Mammut. While today we’d call it a superbike, in the late 1960’s and early 1970’s this kind of spec was simply mind-blowing. From the rear everything looks fairly conventional but appearances can be deceiving. Aircraft-quality Elektron magnesium alloy was used for the mudguards, swingarm (incorporating a structural oil-bath chain housing on the left), fork bridges and footrests. Interestingly, wheels often failed when their spokes were stripped from their housings due to the engine’s torque–additionally, rear tires could be expected to last as little as 100 miles. Here’s what makes the Mammut; an air-cooled, sohc 200cc inline-four sourced from NSU and capable of propelling the big bike to 60 mph in around four seconds. Modifications included fitting a new gearbox and clutch, as well as reworking of the engine’s sump, carburetors and exhaust. Check out the Münch branded gauges. The odometer clearly displays the claimed 5007km, and for those who are curious 250 kp/h is roughly 155 mph.
