Kirkham lead strong lead during Saturday’s competition proved too much for Madill.

Kirkham was quick out of the gate and led from the second straight.

Madill finished second with Melbourne’s Joshua Callan just off the pace in third. National Champion, Billy Jolliffe from Newcastle, clashed with Madill in the first turn finishing in eighth spot.

Kirkham now leads the series and is 195 points ahead of nearest rival, Callan.

Kirkham said he was not fazed by Madill sitting behind his wheel in the final at Melba.

“I knew that I had the horsepower to get by him,” Kirkham said.

“If Luke felt the way I did I don’t think he could’ve come around me.”

The 24-year-old suffered two flat tyres and a broken back wheel mechanical issue, but the problems did not deter him.

Kirkham, who now resides in Adelaide, recently gave up his full time work as an electrician to focus on BMX and his Olympic goal to reach London in 2012.

With Adelaide rider, Sam Willoughby securing the World Cup title this year, Kirkham said he was expecting more South Australian riders on the international scene.

“Adelaide has some good riders at the moment. Even with Sam now in the US there is still his brother, Matt and Anthony Dean is back into training too,” he said. “It’s a really good scene at the moment.”
