Few firms have done more to popularise unit construction than New Imperial Motors, and with a few exceptions this form of construction is followed in their 1936 machines. At the lower end of the scale is the "Unit Minor de luxe" the pioneer of its type. It is of 146cc capacity, and, of course, employs gears for the primary drive, these running in an oil-tight case. This machine has demonstrated its prowess in numerous competitions, and the overhead-valve engine delivers a lively performance. With its fully-enclosed valve and rocker gear, generally compact layout, and full equipment, it is a pleasing little mount, while the gold finish gives a smart appearance.
It has a counterpart in "Model 30" but in this case the engine capacity is 247 c.c., while the front forks, instead of being of pressed steel, are tubular and are fitted with hand-controlled shock absorbers; also, the brakes are larger.
Model 36 "Unidyno" 247 c.c. single-cyl. o.h.v. New Imperial; sump lubrication; gear primary drive; 4-speed gear, with hand control; fuel, 2¾ gals.; 26x3.25 in. tyres.
Price with electric lighting (solo), £47.
An entirely new model is the 247 c.c. "Unidyno" and it is most attractive. The engine is a development of previous designs, and instead of a gear drive for the Magdyno the drive is taken from the timing case and is by chain. This new arrangement results in a very much better appearance, while the inclusion of an engine-shaft shock absorber gives a smoother transmission than formerly.
The tappet adjustment is at the base of the push rods, which are enclosed in tubes. An interesting feature is that the rockers are drilled with oilways communicating with the ball ends which rest in the cupped ends of the push-rods.
A 346 c.c. edition of this model is produced, the two machines being worthy additions to the range. Yet another 346 c.c. unit job is the Model 40. It should be noted that this machine is also sold complete with a light sidecar at a very reasonable figure.
Model 100, “Clubman.” 346 c.c. single-cyl. o.h.v. New Imperial; dry-sump lubrication; magneto ignition; all-chain drive; 4-speed gear, with foot control; fuel, 3¾ gals.; 26x3.25in. tyres.
Price with electric lighting (solo), £57.
The 346 c.c. “Clubman” represents an attempt to provide a machine suitable for the sporting rider. It is of the non-unit type, with the engine mounted vertically in a duplex cradle frame. The carnation and chromium finish is particularly smart. There is also a 247 c.c. “ Clubman,” and the engines used are replicas of the Grand Prix racing power units.
Three more unit-construction models complete the range; the 496 c.c. o.h.v. “Unit Major ” is a standard production and has a counterpart in the “Unit Clubman,” which has a sports specification.
Then there is the 550 c.c. “Unit Major” side-valve model, which is offered primarily for sidecar work.
Visitors are much interested in the supercharged racing twin and the streamlined “ 150” which are on view.
