No very great changes will take place in the 1922 Ivy models. A neat little dummy belt rim brake will be added to the front wheel, the tank will be slightly modified, though it will retain the distinctive Ivy outline, the spring forks will be slightly altered to conform with the type of fork associated with the name of Brampton, and a new cylinder will be fitted to passenger machines.
This cylinder is an imposing casting with long deep ribs and an increased cooling area for the head. Its introduction is due to the fact that the manufacturers considered their standard cylinder more suitable for solo and sporting work, and rather on the high efficiency side for towing heavy loads. The new casting has been designed for general all-round performance, and a considerable improvement in pulling at low speeds is claimed. From our own experience, we are aware that slow pulling was always a commendable feature of Ivy engines, so that the new design should be remarkable in this respect.
Forecast and Guide to Olympia
This machine is distinguished by its robust and clean framework and good quality detail fitments. Brampton forks and dummy belt rim brakes on both wheels are included in the specification. A roomy sidecar finished in mauve to match the tank may be supplied if desired. The big twin outfit is now otwred with a choice of power units - J. A. P. or Blackburne - and of final drives - belt or chain; otherwise it is unaltered. Other Rex-Acme models include a two-stroke in various forms, and J.A.P. and Blackburne-engined machines of 2¾ h.p. In the latter case, the drive is by chain, and a lightweight three-speed Sturmey gear box is incorporated.
