MSA issues Cadet Class performance update

The Motor Sports Association (MSA) has confirmed the performance restrictions that will be imposed on existing Cadet kart engines – the Comer W60 and Honda GX160 – from 1 January 2013 in order to ensure parity with the incoming IAME Parilla Gazelle 60cc UK, the new power unit for the MSA British Cadet Kart Championship.

Having carried out extensive testing and data evaluation in conjunction with Zip Kart (representing Comer) and the ABkC (representing Honda), the MSA has concluded that introducing the following restrictions from 1 January 2013 should ensure performance parity across the Cadet category:

  • Comer: additional ballast of 4kg, taking the Class minimum weight from 99kg to 103kg (equivalent to the IAME and Honda)

  • Honda: insertion of a 16mm inlet restrictor between the carburettor and cylinder.

The Cadet Class regulations are detailed each year in the MSA Kart Race Yearbook; the 2013 edition will confirm that the MSA, at 28 days’ notice, can vary the performance restrictions of any Cadet Class.

Rob Jones, MSA General Secretary and Kart Committee Chairman, said: “In terms of understanding the performance parameters of the new IAME engine in contrast to the existing Class engines we feel that we have now achieved all that we can outside of a competitive racing environment. The full performance picture should therefore become clearer once the engines are run in anger for the first time next season. Obviously there may be a need for further performance managing measures and the MSA will continue to monitor performance. We therefore anticipate carrying out a review by 1 March 2013.

“I would like to reiterate that a key philosophy of the tender process has been that controlling speeds is essential to the risk management process and the maintenance of our excellent safety record. We must recognise the fact that Cadet lap times are now up to 2.5 seconds quicker than they were when the Class was first established, which is why the tender process required an increase in lap times.”
