MOTOR CYCLE DESIGNS.

A great deal of thought is being expended at the present time on motor cycle design and possible further developments in connection therewith. The majority _of British firms are content for the time being to perpetuate their 1914 or 1915 models, with perhaps a few improvements here and there, whilst continuing their experiments and preparatory work lor the introduction of new designs next season. A few English firms have introduced entirely new models for this year, and probably will perpatuate these types m 1920 with such modifications as may then aPPf" necessary. There is reason to suppose that one or two of these firms will market fourcylinder models. We do not, however, anticipate any revolutionary methods in general' design, but think that there will bo a wider tendency to adopt twin-cylinder in preference to single-cylinder engines, and a type that would appeal very strongly to many, if manufactured on a wider scale, : is the twin-cylinder two-stroke. As regards transmission, it seems almost certain that the chain will continue to play an all-important part, but with the introduction of four-cylinder models there will be an extension of the shaft and bevel gear drive, with, as alternative, a worm drive, or even one hi which friction discs are used.
