To be listed in the Guinness Book of Records, who would not want this to happen one time? Franz Langer, the designer of this motorcycle did make it. With the NSU 1000, shown at the Technik Museum Sinsheim, he was holding the record over many years for the motorbike equipped with the one-cylinder engine with the largest displacement.

The basis for this unique machine was a NSU 600 OSL from 1939 in a boosted version which had its capacity enlarged to 1 liter. The motorbike weighing a good 180 kilograms has an output of approximately 40 hp and achieves a top speed of about 90 km/h. To prevent the large-volume engine from stalling during acceleration, Langer had to develop a special clutch for his record-breaking motorbike. The NSU 1000 has meanwhile been outdone by a 1-cylinder motorbike with a capacity of 1,5 liters. To win the record back the "Bison 2000" shown below was built and registered for the world record. The machine is powered by a gigantic 1-cylinder motor with a capacity of 2 liters. Note: The "Bison 2000" is currently not in exhibition!
