KA NSW: Harder Tyres & A Yamaha Class

KA NSW today announced it will introduce harder, longer wearing tyres for several classes, and that Yamaha engines have been removed from KA3 & KA4 into their own category.

We are not normally in the business of publishing rumours, however it’s interesting to note that we heard from an ‘insider’ of similar proposed changes and tyre allocations (plus allowing the KA100 to run in TaG Restricted) some time ago – but it was for Karting Victoria. As yet, there have been no official updates from Karting Australia or Karting Victoria on the matter.


KA NSW press release

KANSW introduces more-durable Option Tyres for Club and Zonal Competition

• Extensive testing program determines new, harder compound optional tyres
• Yamaha engines from KA4, KA3, and TAG100 all included in their own standalone class, KA4 and KA3 become solely IAME KA100 classes

Following a lengthy process led by Karting Australia, the Executive Committee of the newly formed Karting Australia (NSW) Inc. (KANSW) has confirmed its intention to introduce two more-durable, harder compound option tyres for Club and Zonal competitions.

Bridgestone’s well-known YDS tyre will become the option tyre for Cadet 9, 12 and K4, while the trusted MG AZ (Red) has been selected as the option for X30 and TaG125 classes.

Both tyres have been selected based on their durability, with testing proving them to be longer-lasting tyres with acceptable performance characteristics.

Also of note with this announcement is that the Yamaha engines have been removed from the KA4 and KA3 classes, while the TAG100 has been removed as a standalone class, with all Yamaha engines now included in their own class.

The selection of the new optional tyres now provides a logical point of separation between Club and Zonal events and competitions from major State Series and Nationally Permitted events where the prime tyres are to remain in use.


“Further to the recent announcement regarding the significantly lower State administration fees, the introduction of more durable Option Tyres for a substantial portion of our events is yet another important step towards lessening the cost for Karters in New South Wales,” said KANSW President Dave Laughton.

“Karting Australia has been considering the implementation of an Option tyre program for considerable time, and the KANSW Executive Committee is pleased to have been able to move fast with the national body to announce the introduction of these new tyres.”

The option tyres provide flexibility for Clubs and organizers of major Zonal and State Series, and State Trophy event organizers when consideration is given to what is best for each, whether more durability or greater performance is deemed to be more important.

The Option tyres for each Class will be specified in KANSW’s State Regulations for Club and Zonal level competitions.

Organisers of the State Cup and State Trophy (stand alone events of significance in NSW such as the Brian Farley Memorial event) will be able to nominate the selected tyre – either the option tyres or the prime tyres in the event Supplementary Regulations.

For National level events – State Championship, National Cup and the Australian Kart Championship, where outright performance is sought, the selected Prime tyres will continue to be used.

The Bridgestone YDS option tyres are not currently held in stock in Australia and will be manufactured to order, so there will be a delay of some months before the introduction dates.
