MOTOR-CYCLE ENGINES

Owners of the smallest and most inexpensive cars, states a motor-cycling writer, have more often than not at least four cylnders to propel them. Many of these motorists have gravitated to ears from motor-cycles, and one of their first thoughts when driving their cars must be to wonder why they ever put up with single cylinders ,in their two-wheelers.' Yet .at present the single-cylinder motor-cycle is practically as supreme, if popularity is a criterion, asit was two decades ago.

There are, however, signs of a change and many thoughtful motor-cyclists are wondering why they should be denied the smoothness and even torque obtain able from a four-cylinder engine.

Litle four-cylinder car engines of 750 c.c. are proved successes, and, as many high-priced motor-cycles have engines far in excess- of this capacity, there seems no reason why a four-cylinder engine should not be common practice in two-wheelers.

The suggested introduction of a ''flat four" canont fail to attract considerable attention from the more thoughtful motor-cyclists and from designers of these* mounts. ■ .

The subject is a fascinating one, and is of interest to many more people than active motor-cyclists in that if four cylinder motor-cycles were usual the noise problem would automatically be solved.
