P17

Worth mentioning as well is the swinging arm front wheel suspension, unsurpassed in its type, with hydraulic damping in the fork legs.  A special strut to receive the brake reaction ensures consistent brake properties.  Also the large alloy brakes with grey iron ring cast in deserve praise.

Very beautifully and practically the steering head part was solved.  The headlight is organically melded with it and the steering damper between the adjustable handlebars with a special finesse includes the steering lock, which is secured against moisture ingress with a small cover.

One of the many nice and practical small things about the Adler MB250 is the toolbox, attached by hinges on the bottom edge and opening outwards, which can be unlocked and serve at the same time as a tool tray.

Also important is the carefully  graded rear wheel suspension (and finely adjustable depending on load) with built in in oil filled damper units.

Of interest is the interior of the Adler twin-cylinder motor with its centrally split crankshaft on one end of which is attached the easily accessessible dynamo-generator and on the other side the multi-plate wet clutch.

Power transmission to the four-speed gearbox is via quiet-running helical gears.  Especially notable is that the dynamo, clutch and all parts of the drive can be removed without taking the engine out of the frame.

A special treat:  the Adler racing motor, equipped with twin TT carburettors, last year built into a number of experimental machines which in races achieved peak speeds of up to 153 KPH.

This motor, which has been developed from the production motor, is built into a special frame.  The racing version of the Adler MB250 is only being built in limited numbers in order to develop the next generation of machines.
