The German elite motorbike of 2nd World War era

The name of the manufacturer NSU Motorenwerke AG of Germany may be no longer known now, because since 1969 has been merged into part of the Audi incorporated in Auto Union AG, which also consisted Volkswagen therein. So NSU has now become part of one of the circles on the Audi logo.

The name of the manufacturer is unique only stands for the city where they started, namely Neckarsulm. In fact, at first in 1873 the factory was not a special manufacturer to make a motorcycle or car, that is only a textile factory. But later developed into a motorcycle factory in 1901, because the world motor racing event began to hit Europe and America at that time.

NSU began to be glimpsed by the motorcycle racing enthusiast when Martin Geiger, a British racer used one of the NSU motorcycles on the Isle of Man TT despite only occupying the fifth position. Furthermore, in 1930-1950, the NSU became one of the motorcycle brand that counts the world of motorcycle racing at the time.

In 1930 the NSU was became the first German manufacturer to use an OHV or Overhead Valve engine configuration. Valve configurations that minimize side-valve engine deficiencies are commonly applied by other manufacturers, such as slow gas flow, combustion chamber shape is too large, and low compression of course power generated by side-valve was low. Apparently the engineer who designed the OHV engine on a NSU motorcycle is Walter Moore from the British manufacturer, Norton.

In fact, before designing the engine by themself, NSU relies heavily on design and material supplies from BMW and DKW manufacturers. Their original design engine was different from the double-cylinder engine supply of those two manufacturers, as well as the dependence will only make them left behind in the arena of motorcycle racing.

When the machine is self-produced and well-tested on the racecourse, then NSU direct offers the motorcycle models with special components for the race, on various engine capacities, such as 200, 350, and 500 cc. The capacity of the machine is tailored to the competition class of motorcycle racing that was rampant at the time.

One of the first motorcycle models to use a machine with an OHV configuration is the NSU 601 OSL that began production in 1938. And OSL itself means Overhead Luxury Racing, which uses an engine with 562 cc capacity, which can generate 24 horsepower @ 3,800 rpm.

The NSU 601 OSL also features the Bosch magnito and Amal carburetor. This motorcycle uses a 4 speed transmission system with multi plate clutch. On the back of the rigid without suspension and tubular frame. For brake devices still use the drum. The weight of the motorcycle reaches 185 kg and tank with a capacity of 12 liters is enough to explore as far as 240 km. Its top speed is 130 km/h and is a fairly fast speed figure of that era.

The NSU 601 OSL is actually a non-military motorcycle product with aluminum cylinder head and chrome-plated exhaust that looks classy in its time. But when Nazi officials were interested in it in the late 1930s, the NSU manufacturer was ordered to make the military version of the NSU 601. With the main characteristics of the second seat, twin pannier bags and matt black muffler. This bike was used for courier and escort tasks for high-ranking officials of Wehrmacht (Nazi German War Force) at the time.
