The Adler M 100 is a small motorcycle from Adlerwerke vorm. Heinrich Kleyer AG in Frankfurt am Main . It was built from 1949 to 1956 and with around 35,000 units was the brand's most successful model.

history

Before the Second World War , Adler manufactured cars, motorcycles with Sachs engines, bicycles and office machines. The war interrupted this production in favor of armaments . A new start was in 1948, contrary to the original plan without automobiles. In view of the great need for inexpensive motorized two-wheelers, Adler developed a moped with an engine limited to 60 cm³ , as prescribed by the Allies . However, this capacity limitation only existed for a short time, so that on October 11, 1949, the general operating license for the Adler M 100 with 100 cc engine was granted.

engine and gears

The Adler M 100 has an airstream cooled Eagle single-cylinder two-stroke engine with a flat piston, reverse circulation and a 16-mm-Einschiebervergaser of Amal or Pallas or a 17-mm Bing - carburetor . The displacement is stated on the nameplate as 98.175 cm³ (bore and stroke 50 millimeters); the output is 3.75 hp (2.8 kW) at 4800 rpm and a compression of 1: 5.7. The electrical system consists of a Norisring flywheel magneto light with 25 W light power at the right engine and a 6-volt battery; the rectifier for the charging current is located in the headlight housing. The engine is started with a kick starter .

A three-speed gearbox with foot switch is flanged to the left of the engine; a single-disc dry clutch sits directly at the end of the crankshaft with double ball bearings . The gearbox can be easily removed for repairs that may be necessary. The drive force is transmitted to the rear wheel via a roller chain.

landing gear

The chassis consists of a double tubular frame and a seamlessly welded pressed sheet metal front fork with pushed short swing arms, coil springs and adjustable friction shock absorbers. The handlebar is adjustable. At the rear, the M 100 has an undamped telescopic suspension ( straight-line suspension ). The two brake drums have a diameter of 125 mm; the brake pads are 20 mm wide.

Furnishing

The standard equipment of the Adler M 100 included, among other things, an anti-theft device in the steering head, an illuminated speedometer built into the headlight, a tool box in the fuel tank, a saddle with compression springs and a luggage rack suitable for a pillion seat. Fold-out side supports on the footrests proved to be inexpedient and were replaced by a center stand that could also be retrofitted during the construction period.

Others

The Adler M 100 is a low motorcycle that weighs 70 kg when ready to drive. The top speed is 70 km / h, which is higher than most of the competition in its class; only the NSU Fox with a four-stroke engine and 6 hp is faster. However, the top speed of the little eagles is accompanied by stronger vibrations.

At the beginning of the construction period, the Adler cost 845  DM , but the price rose in 1952 with the standard black paintwork to 900 DM, with chrome parts 935 DM and in red 965 DM. The rival brands were cheaper throughout, but a NSU Fox was considerably more expensive at 1135 DM. The standard consumption (measured at a constant 2/3 of the top speed + 10%) was 1.9 liters per 100 kilometers.

1. ↑ In Dieter Jorzick / Johann Kleine Vennekate, Adler Motorräder, p. 28, it says: "Due to its great success, the Adler M 100 remained in the Adler-Werke sales program for eight years, from 1949 to 1957." In the Adler Schwinge company magazine - With the new Adler program for the 1957 season , issue 4/56, the Adler M 100 is no longer mentioned, so production obviously ended in 1956.
