What was less of a given was just how good the Bendigo eight-year-old might be.

But early indications are that Harry has certainly inherited plenty of his family's ability in the go-kart.

Little more than 12 months after taking up the sport, Harry has racked up an impressive list of state and national level wins and placings.

He is currently placed fifth in the national championships, after emerging victorious in the most recent round at the Go Kart Club of Victoria's complex in Port Melbourne.

Harry beat out 22 other competitors to win his class (cadet nine) of the City of Melbourne titles, which doubled as a round of the national championships.

This weekend he will line-up for the second last round of the Rotax Pro Tour at Puckapunyal. 

He enters the round ranked fourth.

His father Craig said Harry had been around go-karts his entire life, with his uncle Brett Arnett responsible for working on his engine.

"It's in his blood - he had no choice but to race go-karts," he said.

"It's his first year and he's doing exceptionally well. 

"Next year we'll follow the same scene and they have trips to the world finals over in Europe.

"Harry missed out in a few good rounds, but he's making up for it towards the end.

"The boy in front is just a little bit too far in front for Harry to catch him."

Craig, a two-time state champion in the 1990s, also made his name as a speedway driver.

Not surprisingly given the pedigree, Harry has an older brother Cory, who has also proven no slouch in the kart.

The youngster will spend another year in the cadet nine class (for drivers aged seven-to-nine) before stepping to cadet 12.

Craig said there were few places the family, including mother Karen, wouldn't go to indulge in their passion for go-karting.

"Bendigo is his home club, but we take Harry and Cory all over Australia, anywhere from Warwick in Queensland, to Ipswich, over to Bolivar and Monarto  in South Australia, New South Wales, Eastern Creek," he said.

Harry said he enjoyed the thrill of winning and passing other drivers and hoped to one day become a V8 Supercars driver.
