MotoOnline.com.au will be bringing updates direct from Eastern Creek as they happen, featuring both the Superbike and Supersport classes from the fourth round of the 2009 Woodstock Bourbon Australian Superbike Championship.

Supersport Race One
Yamaha Racing Team rider Jamie Stauffer won the opening Insure My Ride Australian Supersport Championship race over teammate Bryan Staring, the pair of YZF-R6s battling at the front of the field throughout the race.

Stauffer led the opening laps from pole position until Staring made a move mid-race, but it was Stauffer who made his way back through on the #1 machine.

Staring led laps 10 and 11 of the 12, but it was the defending champion who crossed the stripe first on the final lap to win by just 0.139 over Staring, while Evolution Sports Group Honda rider Shannon Johnson was third.

Team Joe Rocket Suzuki rookie Troy Herfoss had moved into second in chase of Stauffer until a front-end crash at turn nine, setting the fastest lap of the race with an incredible 1:32.680 – just short of the current lap record held by Stauffer.

Check back later for race two, where Herfoss will be sure to be keen to make amends for his crash in the opening leg. Superbikes coming up.  

Superbike Race One
Controversy at the start of race one when Glenn Allerton’s Motologic Racing Honda developed a misfire similar to Queensland Raceway, but he made it out to the start with just the warm-up lap completed on his spare bike.

Waters led the field away and comfortable led the opening half of the race from Allerton, with Dan Stauffer also striking in the top three during the first half.

Allerton’s teammate Wayne Maxwell began to make his way through, while Craig Coxhell on the privateer CJC Racing Honda moved into a very solid third position as the Yamahas of Dan and Jamie Stauffer slowly dropped down the order.

The major battle developed from fifth to eighth when the Yamaha boys fell into the clutches of the Suzukis of Shawn Giles and Robbie Bugden, with the Suzukis making their way through on Dan in the closing laps. Giles also passed Jamie.

Allerton and Waters crossed the stripe together on the final lap and then Allerton made his way through to the lead for the first time in a brilliant battle for the race win and series lead.

Allerton took an incredible win from Waters and Coxhell, with Maxwell fourth from Giles.

Supersport Race Two
Staring got redemption in the second Supersport leg of the day, edging out fellow YRT rider Stauffer to the line in a drag race that had the healthy crowd in the grandstand on their feet cheering.

However it was Stauffer who won the overall thanks to winning the point for pole position in yesterday’s qualifying, but Staring will still be satisfied with only losing out one point in the series stakes.

Star of the day has to be Herfoss, the rookie sticking with the Yamaha pairing for the entire race and even challenging and passing Staring at one point, before finishing the race a solid third to round out his day in his first ever ASBK round at Eastern Creek.

The scrap for fourth and top privateer honours was between Johnson and Scott Charlton, with Johnson getting the better of his fellow Victorian and both finishing ahead of Kawasaki factory rider Ben Attard.

Superbikes are still to come for their second and final leg of the day.

Superbike Race Two
Waters took off from the start in race two, building up a quick gap of over five seconds and setting a new lap record of 1:30.9, which is just over half a second off of the 500cc Grand Prix lap record at the circuit.

Waters took a comfortable victory in what was the first for the 2009 model GSX-R1000, adding it to his pole position for the overall win for the weekend and closing in on the series lead.

Second was a great ride by Maxwell after passing teammate Allerton at the mid-point of the race, while Bugden had a better ride this time out to take fourth place after Allerton got the better of him on the final lap in a thrilling battle for second through to fourth.

Giles narrowly edged out Kawasaki’s Kevin Curtain in the race for fifth, while Yamaha teammates Dan and Jamie Stauffer were seventh and eighth in the final proceedings.

Top privateer was Coxhell in ninth after feeling the effects of the flu, while Zac Davies rounded out the top 10 after holding off both Grant Hay and returnee Marty Craggill.

Overall victory went to Waters, from Allerton and Maxwell, the trio continuing their overall podium run.

Waters was simply too good today, though! Great ride and excellent work by Phil Tainton and the Team Joe Rocket Suzuki crew.
