Townley is one of the stars lining up at Carisbrook on November 20 in a Super X event which will also feature top Australian rider Chad Reed.
Townley said he could remember watching rugby games at Carisbrook.
"I've had a lot of friends go down there for university and they've always had great stories about Dunedin and going to Carisbrook," he said.
"It will be cool to get out and have a ride on the House of Pain."
Townley (25) has been back on the bike this year after two years off as he battled to get over a nasty shoulder injury.
He tried various remedies but eventually went back to a surgeon in Belgium who had successfully operated on his wrist in 2003.
The operation to repair the shoulder was successful and, after a long rehabilitation, he has just concluded a season of racing back on the bike in the United States.
He finished fourth in the US outdoor series, notching wins in the US Grand Prix and the Motocross of Nations.
"It was good for me but in some respects maybe a little bit disappointing. But then I think overall I've had two years out of the sport and racing, so to finish fourth was not too bad."
"It was really a physical thing. Mentally, I was a little bit ahead of myself the whole year. But I just made a few too many mistakes physically.
"Getting the strength back was obviously the priority, and I'll be back again next year."
Townley, originally from Taupo, has signed for the Kawasaki CLS team for next year, aiming to win the FIM world championships.
But before that he has the event in Dunedin, which will be preceded by races at Albany's North Harbour Stadium on November 13.
Super X racing has already taken place in three Australian cities and the competition will head back across the Tasman after the Carisbrook event.
Though a pure motocross rider, Townley can see the value of such events as the Super X show.
"In some sense it is a show, but there is some form of race. There are 20 of us lined up and the aim is to win, so there is a race aspect.
"You're a lot closer to the crowd as you're on a football field. There is contact involved and you've got to take the right attitude that it is motocross and you want to win the race.
"The main difference is that it is really tight and confined. It runs up and down so the key is to get to the front and go from there."
