 In September 1922 Villiers announced the details of their new 1923 engine range, which included 147 cc, 250 cc and 343 cc engines.These engines featured a radial-finned cylinder head, with both the inlet and exhaust port being at the front of the engine, and they all had the Villiers flywheel-magneto.While the 147 cc relied on petrol-oil mixture for crankshaft lubrication, the two larger engines used a separate oil-feed system.
