Since completing a parity test for the eligible engines in December 2021, Karting Australia has been closely monitoring the parity between the eligible engines in the TaG 125 class.
This monitoring has included the analysing of data from events and private testing at various circuits across the Country.
To achieve the best parity outcome for the long-term benefit of the Class, permission has been provided by Karting Australia for aspects of this testing to be conducted in practice at the Australian Kart Championship. It has also been completed in race conditions at limited events.
All this data has provided valuable further insight into the characteristics and performance of each of the eligible engines on the LeCont SVB tyre on various track configurations and conditions that have changed with the introduction of the new tyres in 2022.
Following the analysation of this data, Karting Australia advises of the following changes to the Class Rules for the TaG 125 Class with immediate effect:
