But after earning his 11th straight triumph of the season on Saturday afternoon, Symons opted to sit out the grand final and hand the opportunity to another young rider.
Seventeen-year-old Ethan Brehaut duly took to the challenging and rain-hit circuit to earn a very welcome outright senior-level victory.
The two are competing in separate classes, Symons in the open and Brehaut in MX2, and yet their racing antics continue to add further excitement to the A Group.
Much to the thrill of all the spectators and particularly motocross captain Carl Wallbridge, Brehaut threatened to carry out a big upset in the second of three 12-lap heats.
After settling for fourth in an opening heat where Owen Waddingham took runner-up 13sec. behind Symons, Brehaut managed to track the leader for the entirety of heat two.
He had trailed by a second through the lap point and swiftly rallied back from some lost ground on the sixth and 10th circuits.
Come the chequered flag, only a second split Symons and the fast-pursuing Brehaut.
Brehaut quickly latched onto Symons again in the third heat – yet this race proved eventful for quite another reason.
One boggy corner was quickly becoming infamous for disrupting riders and Brehaut, who had by then dropped from Symons’ wheel, took a tumble at lap six.
Symons went down just a lap later but, despite this blunder, he still finished 22sec. clear of Brehaut.
The conditions on course were getting to the competitors by that point and only three finished the heat.
Symons’ class rival Joe Holden had called it a day and by then, the star rider had nothing to lose if he chose to skip the all-adults grand final.
That he did.
Brehaut took the initiative and set the pace in his absence, eventually winning by 16sec. from Waddingham as third went to Rhys Melass, earlier a triple victor in the B group.
