Tonight’s fourth round of the Monster Energy Super X, Australasian Supercross Championship, at Auckland in New Zealand will see a first time winner for the 2010 season.

The round winners from the opening three rounds – Chad Reed, Kevin Windham and Justin Brayton – have all returned to the United States to focus on next year’s AMA Supercross, opening the door for the fourth overall Open class winner in Super X this season.

Series leader Josh Hansen is the favourite for tonight’s Quad Challenge main event, topping the seeded qualifying this afternoon for Monster Energy Pro Circuit Kawasaki.

While Hansen has been consistently quick all season, another rider building momentum is Aussie Jake Moss, the Rockstar Motul Suzuki star qualifying second this afternoon.

Two wild card riders will throw a spanner in the works with the impressive Californian Jeff Alessi qualifying third on debut for CDR Rockstar Yamaha, while local hero Ben Townley could surprise come race time in his debut aboard a Kawasaki.

Both Alessi and Townley come into the round under the radar in Auckland as it’s their first appearance of the season, and both have been on the pace within the top four in practice and qualifying today.

Other Australian riders to keep an eye on during tonight’s event are both CDR Rockstar Yamaha’s Jay Marmont and Cougar Bourbon Honda Racing’s Dan Reardon, that pair currently the next best series regulars behind Hansen in the title chase.

Reardon and Marmont qualified fifth and seventh respectively during qualifying this afternoon.
