Clyno Engineering Co., Ltd., Wolverhampton.

Since the spring-frame Clyno sidecar outfit was a very advanced design at its inception, it does not require modification to modernise it. Engine and gear box are both of Clyno design and manufacture, and, while following conventional lines, are neatly carried out. For next year the clutch has been redesigned, and is now of the steel and phosphor-bronze plate type, instead of the cork insert pattern hitherto employed. The cylinder heads and timing gear have also been modified.

Detachable and interchangeable wheels, extremely efficient mudguarding, enclosed transmission, an adequate combined leg and undershield of improved design, and large rubber-studded footboards, contribute to the equipment of this luxurious machine, which, with a Magdyno lighting set (£15 extra) and an imposing sidecar with hood and windscreen, represents the sidecar outfit in its most highly developed form: The spare wheel costs £6 extra.

2½ H.P. Model.

  • 70x70 mm. (269 c.c.); single cyl. two-stroke; petroil lubrication; Amac carburetter; gear-driven mag.; 2-sp, gear; no clutch or kick-starter; gear and belt drive; 26x2¼in. tyres. Price £ 45.

One of the most successful and neatly designed two-stroke lightweights of prewar days, the Clyno makes a welcome reappearance without having undergone any drastic alterations. It will be recalled that its main feature was the absolute simplicity of its unit two-speed gear box.

The offset engine is carried in a loop frame of otherwise conventional design. No clutch or kick- starter is provided, it being considered that paddling off is so simple as not to necessitate the complication of these members. All the Clynos on show have a new finish - black with a cream panel in the tank. Three outfits, one demonstrating the spring wheel side-car and one lightweight, comprise the complete exhibit.
