Nick Isaac takes out NZ National Superkart Championships with Vortex RKZ engine and Tony Kart Chassis.

An average weather weekend led to more than average results for Tony Kart driver, Nick Isaac. After stepping away from road racing in 2016, Nick certainly made his return by winning the 2019 NZ National Superkart Championship with his Vortex RKZ engine and Tony Kart chassis.

“The Vortex RKZ engine ran like a swiss watch and pulled like a train against the worked TM’s, even with a very safe tune, and my Tony Kart chassis was hooked up all weekend with minimal changes needed as usual” – Nick Isaac, Winner NZ National Superkart Championship
