STAND 66 : Workmanlike Range of Sports “Empire Star” Models : Improved “Blue Stars” and Front-wheel drive Three-wheelers

B.S.A Cycles, Ltd., Small Heath, Birmingham, 11.

Model Q.8, “Empire Star.”—496 c.c. single-cyl. o.h.v. B.S.A.; dry-sump lubrication; magneto ignition; all-chain drive; oil-bath primary chain case; 4-speed gear, with foot control; fuel, 3¾ gals.; 26x3in. (front), 26x3.25in. (rear) tyres.
Price with electric lighting (solo), £65 10s.

A REALLY workmanlike range of new models is exhibited, these being the “Empire Star” 350 c.c. and 500 c.c. series. Although they follow the lines of the already well-known “Blue Stars,” they embody many refinements and improvements ; material in particular has been a point of special attention, and metals of the most specialised class have been introduced wherever it has been found that the latest developments of metallurgical science would produce greater reliability and enhanced performance. The special hardened-iron cylinder is a case in point.

The frame used for these models is particularly substantial and is of the forged backbone type, with duplex seat and front down tubes, these components being bolted to the main member. The rear stays extend forward under the gear box and join the front down tubes at the front of the crank case, forming a complete cradle frame.

Another detail is the enclosure of the primary drive in an aluminium oil-bath case, and the enclosure of the clutch therein in an oil-tight cover. The clutch friction material is of a special type which will function even should oil reach it, consequently clutch trouble in any circumstances should be a remote contingency and there should be no possibility of drag.

That the “Empire Stars” have been designed from practical road experience is evident from such details as the shield between the front down tubes, the guard on the lower rim of the chain (it is fixed to the long torque member anchoring the rear brake plate), the spring-up prop and rear stands, the hinged rear mudguard, the useful lifting handle, and many other small details.

The “Blue Star” range, the 250 c.c. o.h.v. models, and the medium-capacity o.h.v. twins—500 and 750 c.c.—follow somewhat similar general specifications.

Model B.1.—249 c.c. single-cyl. side-valve B.S.A.; mechanical lubrication; magneto ignition; all-chain drive; 3-speed gear, with hand control; fuel, 2¼ gals.; 26x3in. tyres.
Price with electric lighting (solo), £35 10s.

In the case of the 250 c.c. side-valve model, the B.S.A. concern provides a simple machine for the novice. It is a neatly constructed yet robust solo type, with a detachable-head engine.

Model T.W.10 Three-wheeler—1,075 c.c. four-cyl. side-valve B.S.A.; mechanical lubrication; coil ignition; 3-speed gear and reverse gear, with hand control; fuel, 4 gals.; 27x4.5in. tyres.
Price with electric lighting, £125.

To those who require car comfort and sports car performance at the lowest overall cost, the four-cylinder front-wheel-drive three-wheeler offers these qualities.

Two four-cylinder models are available, one with a normal body, and a de luxe model at £128 The latter has a body of the sports type with a two-colour scheme, dropped doors, folding screen, and disappearing hood.
