Grabham took out the 85cc 4-stroke Modified 7-10 Years gold medal and added to his success with silver in the 65cc 9-13 Years and the 85cc 2-Stroke/150cc 4-Stroke Standard Wheel 9-11 Years.

The Bathurst junior has familiarity at both the national level and with the course at Somersby's Allen Park, and it showed in his performances.

The track championships are a great test for Grabham since he won his three medals across three different bikes.

"We had some confidence that I could go alright," he said.

"Getting that first place was really good but it would have been nice to win the other two."

It was almost a golden treble for the young Bathurst rider if not for a couple of unfortunate moments in his silver medals rides.

There's still more to come for Grabham as he attempts to tick off a list of state events.

"We've got the South Australian titles coming up in two weeks, then Victoria and New South Wales," he said.

Grabham enjoys the chance to ride across as many different categories as possible.

"My 150cc's got the most power out of all the bikes. If you get in a bump you can give it some more throttle and it'll get out easier," he said.

"The 65's a bit smaller and the mod's about the same size as the 150 but with about half the power."

Gold Coast's Rory McQualter narrowly beat Grabham in the 65cc race and Kempsey's Jayden Holder just saw off the Bathurst rider in the other event.

Grabham's father Damien couldn't be prouder of his efforts.

"Me and my wife are super proud of him. He did so well," he said.

"It's good to compete in the different events because they get a lot of racing that way. He was quite competitive in all of them.

"He actually led the 65cc race until the last corner but he unfortunately hit a bump, lost a bit of momentum then got passed.

"In the other one he got a bad start but he managed to fight his way back into second."

Grabham rides for the Cowra Motorcycle Club, who had a number of successful riders attend the event.

Forbes native Tom Drane added to the gold collection with his wins in the 100-150cc 2-Stroke 13 to 16 Years and the 100-150cc 2-Stroke/200-250cc 4-Stroke 13 to 16 Years.

Sam Drane also found the top step of the podium with his ride in the 65cc 7-9 Years and was a finalist in the 85cc Modified 7-10 Years.
