Price, a winner of the AORC title on three previous occasions, came into the Rd11/12 finale at Heathcote, Victoria, with a 28-point lead over his nearest rival, Glenn Kearney of the Husqvarna Enduro Racing Team.
Overcoming a poor start to Saturday's Round 11, Price fought back to take the race win and an unassailable lead in the championship. Sunday's Round 12 was largely academic, but Price still rode hard to finish the round second behind CDR Yamaha's Daniel Milner.
"I'm over the moon," Price said after the championship win. "The whole KTM team has worked really well, and helped me achieve my goals, which was to get back on the bike after the injury last year and try to win races again.
"I didn't think winning a championship would come again so soon, but that's what we strive for."
Price finished the 2014 AORC on 260 points, followed by Daniel Milner (CDR Yamaha - 218), Glenn Kearney (Husqvarna Enduro Racing Team - 211), Josh Green (Active8 Yamaha - 208) and Chris Hollis (CDR Yamaha - 191).
Price's 2014 AORC title comes on the back of wins at Hattah, Finke and the WA Desert Tri-Series, as well as runner-up results in this year's KTM Enduro-X Series and the Australian Four Day Enduro.
