Motorcycles at the 1922 Olympia Show

The Olympia Show.

H.T.

Stand 46

Known previously as the Hagg Tandem, the H.T. machine is now marketed in two forms, one a simple semi-stripped sporting motor cycle of conventional design, and the other a double- or single-seated two-wheeler, elaborately protected, and intended to attract the elderly comfort-seeking rider.

Barr and Stroud sleeve-valve engine and Burman two-speed gear box are common to both, but otherwise they are as the poles apart. The tandem has a well-tested spring frame and shields enclosing the entire mechanism.

XTRA CAR.

Stand 47.

No vehicle built others such a remarkable choice of power units, while otherwise remaining essentially the same as the 1923 Xtra car. A two-seater model has been evolved; in the runabout form, it is fitted with a 347 c.c. Villiers engine and costs £105; in the "touring" form a 976 c.c. V-twin J.A.P. is substituted, when the price is increased to £122 17s., incidentally the lowest priced two-seater three-wheeler on the market.

On this unconventional vehicle, two pairs of transverse springs act as front axles and carry car type stub axles on pivot pins. Rear springing is by two quarter-elliptic springs. The body also acts in the same capacity as a chassis on a normal car.

G.S.D.

Stand 44.

Notable if only as the sole British shaft-driven motor cycle, the G.S.D. embodies other advanced features in its design, including a transversely set engine in one unit with a four-speed gear box and a duplex frame.

A 350 c.c. White and Poppe two-stroke engine is normally used, but an additional model will be shown with a V-twin 976 c.c. J.A.P. unit.

An underslung worm conveys the power to the back wheels which is easily detachable, although tyre repairs may be still more quickly effected by utilising the provision made for removing the inner tube.

26x3in. tyres and internal expanding brakes on front and rear wheels are features common to both models. Mudguarding has received considerable attention.

ECONOMIC.

Stand 45.

Last year the Economic was almost in a class by itself, both as regards price and engine capacity. To-day it is far from being alone in these respects, but the fact that it has a flat twin two-stroke engine and friction transmission prevents it from losing entirely its attributes of distinction. The capacity of this engine is 165 c.c.

Nine speeds are given by the friction gear, but these are necessarily within fairly confined limits, actually from 6 to 1 to 19 to 1. Final drive is by belt.

Improvements for next year have been made in the finish black and gold - and in the fitting of a Capac single-lever carburetter.
