ONLY ONE four-cylinder F.N. was necessary in the recent Londom-Edinburgh classical run to demonstrate the wonderful reliability and advantages of this four-cylinder example. All eyes, of course, were centred on this one model, and the rider made an exceptionaily fine performance, qualifying for the gold medal, and was one of the handful who decided to return to London on his machine.

Unless you have carefully studied the four-cylinder principle, you cannot appreciate the advantages its simplicity offers over other single or multiple-cylinder machines.

The explosions are less in volume, with consequent silence. The running is sweeter; whilst the fact that belt troubles are entirely obviated through the bevel gear transrnissior, renders a run on the four-cylinder F.N the most delightful experience motor cycling offers. We shall be pleased to answer any question, little or big, you wish to learn.
