Enfield Cycle Co., Redditch. Vickers, Ltd., who are manufacturing the new engine for the Royal Enfield combination, have already such a well-deserved reputation that one cannot doubt the quality of their product. The engine itself, which was described in the last issue of The Motor Cycle, is of the standard V twin type, but has fully forced lubrication by a very, accessible pump outside the timing case. An auxiliary hand pump is also provided. The Enfield two-chain drive to the countershaft, with selective clutch gear change, is retained, as also the handle starter; in fact, apart from the new engine, there is but little change in the outfit, except that a very neat removable rear mudguard and stand is now fitted. Probably the most remarkable point about the outfit is that a machine of such splendid quality and performance should be offered at a price which is smaller than is asked for many single-cylinder sidecar machines of half the power. Both large and small models are fitted with Enfield spring drive to absorb any chain snatch.

  • 2¼ h.p.; 64x70 mm. (225 c.c.); single-cylinder two-stroke; petroil lubrication; Amac carburetter; chain-driven magneto; two-speed selective clutch gear; all-chain drive; Palmer 24 x 2 in. tyres. Price £65.

The most novel point of the Enfield light-weight is the optional incorporation of a kick-starter, adapted to the Enfield two-speed gear. The countershaft has a gear wheel on its extreme end, and a gear sector is fitted to an extension of the front chain stay lug. The magneto drive is also noteworthy as an example of simplicity in design; it is driven by the low speed chain from engine to countershaft, which forms, as it were, a triangular drive, including engine sprocket, magneto sprocket, and countershaft sprocket.
