David Sera dominated the opening round of the Rotax Pro Tour.
Australia's karters have upped the pace — and profile — of the sport with a return to the CIK championship.
The championship karts use similar engines and tyres to those in the world and European championships. More grunt and more grip means more entertainment and the second round of the series is at Port Melbourne's VACC Park on Friday and Saturday, running alongside the Rotax Pro Tour.
The rejuvenated series has attracted interest from as far afield as New Zealand.
Kiwi duo Mitch Cunningham and Tyson Pearce had mechanical issues in the opening round in Newcastle last month and Sydney's Damien Radosevic is the points leader.
Radosevic impressed in the high-horsepower class in Newcastle and is being touted as the driver to watch this weekend. More than 100 competitors will line up in the five categories that make up the Rotax Pro Tour, with drivers ranging from 13 years old in the Formula JMA category through to the older generation in Rotax Over 35s.
Melbourne driver David Sera dominated the opening round of the Rotax Pro Tour and will again be the driver to beat.
Qualifying will be held on Friday morning with heat races in the afternoon.
The pre-final and finals will be contested throughout Saturday.
