Porte started last year's Tour as BMC co-leader with American Tejay van Garderen, but it was soon clear that the Tasmanian was their main chance.
He finished fifth overall, Porte's best Tour result and, but for some rotten luck, he would have been on the podium.
BMC management soon made it clear that this year, their Tour de France strategy would revolve around Porte.
"Having grown up as a big fan of the Tour, to be finally having that opportunity to lead a team ... it gives me a lot more motivation," Porte told AAP.
"It's nothing against Tejay, and it's not an ego thing to have the team backing me.
"I am super-motivated to repay the team's faith, sending eight guys there just to help little Richie Porte try to get across that finish line in Paris in the best position possible."
Porte points out that being one of the Tour's big favourites is exactly why he left the security of a super-domestique role at the powerful Team Sky.
There, he had helped his good friend and three-time Tour champion Chris Froome, but Porte wanted a lot more.
So after his first year at BMC, Porte feels lofty ambition rather than pressure as the team's No.1 Tour rider.
"I wouldn't say it's affected me at all - probably more last year, when I was a new rider on the team," he said.
"The team wants to know what you're doing whereas, this year, they trust me more."
Porte will end a five-month break from Sunday at Adelaide's Tour Down Under.
It will be his first race since crashing out of the Rio Olympics road race with a broken shoulder blade.
Given his big goals in July, Porte did not race at last weekend's Australian road titles.
Instead, his new BMC teammate Miles Scotson was an upset winner with what Porte called an "unbelievable" performance.
The Tour Down Under is a goal in itself for Porte, who has been runner-up for the past two years.
"I'd love to win this race," he admits.
"Adelaide in January - when you get to Paris-Nice and it's rain and snow, you think back to two months earlier, being in Australia, and it's a pleasure to race your bike every day."
But Porte is up against a strong field and he also is unsure of his form.
"It's certainly going to be a shock to the system," he said.
Whatever happens, the Adelaide race will let Porte know exactly where he stands at the start of the biggest season of his career.
Above anything else, after plenty of bad luck last year, Porte just wants a clear run at his goals.
"I guess you can't do much to change luck, can you But, I just hope this year, I'm more on the end of things going right for me - that's all I ask," he said.
