A newcomer to the motor cycle world, the Ajax Junior is one of the cheapest lightweights in the Show. The makers claim that it is in no sense a cycle, but a motor cycle; we should say that it is a step between the two, for the tyres fitted are not much larger than those used on pedal cycles. Fitted with a simple type of spring fork, the Ajax Junior is, however, a machine which will appeal to those who require a two-speed miniature to supplant the pedal cycle.
2½ H.P. Model.
70x70 mm. (269 c.c); single cyl. two-stroke; drip feed lubrication; Amac carb.; flywheel mag.; 2-sp. gear; clutch and kick-starter; chain-cum-belt drive; 26x2¼in. tyres. Price £47 10s.
Following conventional lines, with a sloping top tube, the larger two-stroke model employs a Saxon fork and other well-known components. A similar model, but having a 348 c.c. Blackburne engine and Maplestone fork, is shown with two-speed gear, clutch and kick-starter at £62. For an extra £3, a three-speed gear can be fitted.
