New engines are being developed for the CIK classes from 2016 onwards. Manufacturers are pinning their hopes to these new engines to start to reverse the mass migration to Rotax and similar classes in non-gearbox racing. Simpler, lighter engines should appeal to purists and reduce development and maintenance costs. The starter, battery and clutch are to be removed which will reduce the weight by 9kg. Prototypes tested so far have had decompression valves which means they are very easy to push start. It’s possible there will be a trial in 2015 before full introduction in 2016. Since TAG KF engines replaced 100cc Formula A, ICA and JICA in 2007, national racing in these multi-engined classes has collapsed, especially in the UK where we have none left.
