Team-mate Cody Cooper was fourth overall at Coolum via a consistent 5-3 scorecard on the second of the Motul Pirelli Suzuki RM-Z450s, finishing in that same position overall for the 2013 season.
"It's been an up and down season, but an enjoyable one all the same," current Kiwi champion Cooper commented. "I really have to thank Motul Pirelli Suzuki for their efforts all year long, as well as congratulate Matt on winning the championship."
Combined, Motul Pirelli Suzuki won five of the 10 rounds contested; Moss taking victory at Broadford, Appin, Swan Hill and Toowoomba, while Cooper claimed the Conondale overall.
Team manager Jay Foreman said the championship came as a result of the team's hard work, combined with Moss' determination to succeed in the sport. After finishing a close runner-up in 2012, victory this year was ultra-special for the entire team.
"We had an awesome day, as the whole year has been," said Foreman. "We had to work our way into it with Matt entering the season under an injury cloud, plus he didn't have a lot of racing last year.
"He's built momentum every week and improved so much. It just shows the maturity Matt has gained in his racing today and it's a great result for the entire team.
"Cody was also very consistent for us today and we congratulate both of the guys on the efforts put forward all season long. It's been an exceptional year for everybody involved."
Team Motul Pirelli Suzuki will now turn its attention to the Australian Supercross Championship, which commences at Darwin's Hidden Valley Raceway alongside the Australian Superbike Championship weekend on September 14-15th.
