Stone💎r retired from MotoGP in 2012, as꧋ a two-time champion, aged just 27 claiming he no longer enjoyed the sport.

Marquez, for different reasons, was at his lowest ebb earlier this year bu�𓄧�t his Ducati debut at the postseason Valencia test restored his smile.

Stoner told TNT Sports at Phillip Island: “If you’re not enjoyin♎g it, why are you risking it all?

🌞“If Marc enjoys his racing, he’s not going to want to risk it all f♋or nothing.

“It’s importantꦫ for him to get that enjoyment back. Find a reason to get up in the morning, train your butt off, put yourse🍌lf through these injuries, drag yourself back.

“People see it from the outside. But it’s very d♓ifficult when everyဣthing is against you, your body doesn’t want to do things, but you force it. It takes a toll.”

Eight-time world champion🐼 Marquez has suffered three years of career-threatening injuries and an unꦐderperforming Honda.

This year at the Sachsenring, traditionally one of his f💟avourite tracks, he looked more solemn than ever after five crashes before the grand prix itself forced him to withdraw.

But, now aged 30, the early signs of his decision to quit Honda for Gresini D🌞ucati are that a new ꦕbike could breathe life into his career.

Stoner, 11 years ago, was unable to find a reason to continuܫe.

He commented on his decision to quit early: “If you’re going to ris🉐k everything, to lay everything on the line, you’ve got to do it for a reason.

“Some people f𝄹ind it’s money. Or for whatever reason they do it, for a result.

“For me, I just loved ridin꧅g bikes. Racing was a part of 𒉰it. I got to race, it was fantastic.

“I loved riding bikes the most, I loved eking everything that I could out of🔯 a bike. I ꦆwas very self-critical.

“When these bikes became too much ele🉐ctronics, too much wheelie-control, 🔯the enjoyment disappeared.

“The series became political.”
