The Rex Motor Mfg. Co., Ltd., Coventry
The Rex Acme range includes no fewer than seven models, of which interest will no doubt centre particularly in the two chief novelties. The cynosure of the exhibit is the Rex Minor, a 112 lb. feather-weight of neat and handsome design equipped with the firm's own two-stroke engine of 170 cc.
2¾ H.P. Model.
70x90.5 mm. (349 c.c); single cyl. four-stroke; sleeve valve; drip lubrication; Amac carb.; chain-driven mag,; 2-sp. gear; clutch and kick-starter; chain and belt drive; 26x2½in. tyres. Price £65 15s.
The Rex Acme touring models are obtainable with a variety of engines. The heavy steering head, with special, provision for bearing lubrication, is an excellent feature. The double girder rear stand and the internal expanding brakes deserve notice. On the sports models the straight-through exhaust pipe has a curiously-shaped expansion and tail box at its rear end.
4 H.P. Model.
86x86 mm. (499 c.c.); single cyl. four-stroke; sleeve valve; mechanical lubrication; Amac carb.; chain-driven mag.; 3-sp. gear; clutch and kick-starter; chain drive; 26x2½in. tyres. Price: Solo, £95; with Sidecar, £119/18/6.
This is noteworthy as being the only example of the 499 c.c. Barr and Stroud sleeve valve engine mounted in a frame at the Show. The installation is particularly neat. The Best and Lloyd oil pump beds very nicely into the engine at a height which ensures its safety in a tumble.
