The largest of the Hawker models has been completely re-designed for next year and is now an excellent example of the more substantially-built dual-purpose big single. 700 X 80 mm. tyres are fitted, and the rest of the machine is in proportion. It is not, however, in any way a cumbersome-looking design.

It has internal expanding brakes front and rear.

One model shown is completely equipped, including the new B.T.H. mag-generator lighting set, which is very neatly carried.

2½ H.P. Model.

70x76 mm. (293 c.c); single cyl. two-stroke; sump lubrication; Amac carb.; flywheel mag.; 2-sp. gear; no clutch or kick-starter; chain and belt drive; 26x2 3/8in. tyres. Price: Solo, £39 8s.

Neatness is the keynote of the Hawker two-stroke, which, it may be recalled, earned considerable fame by hauling a sidecar up 5-mile-long Tornapress in the 1921 Scottish Six Days Trials.

Its unusual features are a detachable; cylinder head and a simple system of automatic lubrication. The way in which both its brakes work on the rear belt rim also is not too common.

The flywheel magneto may be used to supply lighting current.

In between the two extremes specified are 250 c.c. and 350 c.c. side-valve and 350 c.c. o.h.v. Blackburne-engined models at £70, £72 10s., and £84 respectively. All three have chain drive and Burman three-speed gear boxes.
