New era for KA2 class in Australia 2027 season

Karting Australia has confirmed the elite Junior category – KA2 will enter a new era in 2027.

After ten successful years, the Vortex DVS-Junior engine will be replaced by the Vortex SV engine, which builds on the proven strengths of other Vortex products while introducing modern features and enhanced performance.

The 125cc water-cooled SV engine incorporates electric start as standard and has already been adopted across Europe, the Americas and Asia. It has also been selected by the FIA as the exclusive engine for the Arrive & Drive Championships reflecting its performance, reliability and consistency on the international stage.

Unlike the current DVS-Junior engine, which was used exclusively in the KA2 category, the SV will be a true pathway engine and will be eligible for use in the TaG 125 and Restricted TaG 125 classes as well, creating a seamless pathway from the Junior Classes through to Senior water-cooled TaG engines.

“The Vortex DVS-Junior engine has been an extremely reliable engine with great parity within our high-performance Junior category of KA2 for a decade. It has been a great platform to be able to showcase the top level of junior talent in Australia,” said Karting Australia CEO Kelvin O’Reilly.

“Technology has changed a lot over the past decade, and we look forward to our drivers benefiting from the modern technology, materials and construction from the OTK Kart Group who produce the Vortex SV engine.

“One of the most important things for our sport is to be introducing a pathway engine, we envisage this will assist with the continual growth of the KA2 class well into the future.”

The Vortex SV engine will be available for purchase in late 2026 through your local kart retailer with special pricing and trade-in opportunities for the current competitors in the KA2 category direct with OTK Kart Australia.
