The Rova Kent was designed and constructed by Messrs. Eglington and Clarke, two prominent members of the Motor Cycle Club. The engine is of the overhead valve type, and has two exhaust and two inlet valves. The four valves are actuated by two long, adjustable tappet rods, extending from the top o£ the cylinder to the timing case. Those tappets work the overhead rocker arms, each one of which is fitted with a compensating device which ensures each pair of valves acting in perfect unison. The cylinder head is separate from the cylinder proper.

One of the most noticeable features of this engine is the cylinder itself, which is fitted with an auxilliary exhaust port. Practically the whole of the exhaust gas is carried away through the this exhaust port, and into a long TT pattern pipe, which extends past the rear axle of the bicycle. The cylinder is also fitted with non-return valves. The tact of the exhaust gas passing through the auxiliary port means that the heat, which is inseparable from a motor engine, is greatly reduced. The two overhead valves act as scavengers to the rest of the cylinder.

The crankcase is of polished gun-metal, as is the timing case. The timing, wheels and cams are of the outside class, end the unique construction enables any desired valve setting to be secured. A chaindriven Bosch magneto is fitted, and the [] type of B and B carburetter. The machine proved itself in the hill climb, held at Golden Grove on October 5, 1912, and on this latest occasion it more than fulfilled the expectations of the designers.
