DKW GB250 2

A streamlined carburetter cover pro-vides dirt- and dustproof encasement.

An incorporated air-chamber system gui-des the fresh air flow and cleans it from dust and other foreign particles. Wear is therefore reduced to a minimum on the DKW, the engine being in itself highly wear-resistant as it contains only three moving partsand engine speed iskept Iow. The cover can be easily removed without tools. On removal the carburetter is readi-ly accessible. The long intake tubę is in tune with a most favourable torque mo-mentum.

The telescopic fork supplies progres-\ sive suspension by graduated spring-ing properties of main- and damper-springs. The rebounding action is absorb-ed by pneumatic rebound dampers. The suspension is remarkably flexible thus enabling long rides to be madę without fatigue.

The transmission units on the rear wheel such as chain sprocket, rear ^ wheel brake and speedometer drive are one self-contained unit. The front- and rear-wheel-brakes are of large dimensions and guarantee perfect efficiency even under heavy sidecar use. Braking efficiency is considerably higher than police regulations demand.
