Six-time AMA Superbike Champion Mat Mladin will quit racing at the end of the 2009 season in order to concentrate on his family and watching his two girls grow up.

The Aussie hardman, who looks on course to take his seventh title despite not racing at Topeka Park last weekend, has won more than 80 AMA Superbike races in a long and distinguished career.

"After so many great years of racing in the USA, I will retire from AMA racing at the end of the 2009 racing season in New Jersey. My career has been long and above and beyond my wildest expectations," said Mladin.

"I won my first national championship on dirt bikes back in 1981 (28 years ago) and have had an amazing career ever since. If I had my time again, I would not change a single decision I have made, in life or in racing.

"I would like to thank my team for their constant hard work. Without these guys, the 80+ race wins and multiple championships would not have been possible.

"I wish to thank my fans. I want you to know that you all have helped me achieve so much. I will miss you. I want to thank my mum and dad for getting me involved in such a fantastic sport that turned into my profession. I love you both.

"My brother and sister for all the miles you done cramped into the back of a little pick up / ute in the early days. These were great times and the ones in racing I will cherish the most. You mean the world to me.

"My daughters are growing fast and it is time I put my efforts into their future.

"My wife, what can I say? You have unselfishly given your time and efforts to this lifestyle of ours. Racing had its down days, but with you by my side it was easy to get up and smell the fresh air, and realize how lucky I am. You have been a rock for so long, and if I could live another 100 years I still would not have the time to repay you for your commitment. I love you babe."
