The above is a specification of the standard sporting model Duzmo, which, on Saturday evening, when The Motor Cycle report was completed, had not arrived on its stand. It arrived on Monday.

Although it may seem paradoxical to say so, the Duzmo sports model is the standard type, the touring model being a supplementary design for the sidecarist. This gives the cue to the machine, which represents one of the earliest efforts to give the sporting motor cyclist a machine that is something more than a semi-stripped modification of a touring model. Today it is not alone in this respect, but the fact that it was among the first in the field entitles it to respect. In designing the engine, and, indeed, the whole machine, an attempt has been made to combine a high road performance with a reasonable degree of comfort. To this end the inclined o.h.v. engine is laid out so that the gases are allowed the freest possible ingress and exit, and combustion head and valve passages have a highly polished finish. Frame design and tyre size contribute towards ease of handling for long-distance riding.
