Factory Yamaha’s Jorge Lorenzo, who was not present at the Malaysian GP following a surgery on his finger, published: "I don’t know what to say on a day like today ... Only that you will be missed - rest in peace Marco."

Lorenzo’s team mate, Ben Spies, shared: "Super Sic rest easy..."

Nicky Hayden posted: "Sometimes life just don't make sense... RIP #58 you were a star on & off track we all going to miss you."

Cal Crutchlow’s post: "RIP Marco Simoncelli! A great rider and all round nice guy. My thoughts are with all his family & friends. I will never forget today... #58"

Former full time and two time wild card entry this year, John Hopkins, said: "God Speed #58 Simoncelli... Your fighting spirit will live on forever!"

Two time replacement rider this year, Damian Cudlin, shared via Titter: “Terrible news. Marco’s gone. Sad day for motor racing and all the llives he touched along the way. Won’t forget you, mate.”

Kenny Roberts and his family sent the following sentiment: "The entire Roberts Family is deeply sadden by the news about Marco. We wish to send our condolences to his family, friends, fans and MotoGP. We will never forget him!"

Jeff Belskus, the Indianapolis Motor Speedway Corporation President and Chief Executive Officer, shared: "We are deeply saddened at the passing of Marco Simoncelli. He was one of the most charismatic figures in the World Championship and had a fantastic future ahead of him in MotoGP.”

“Marco was one of the most popular riders at the MotoGP event at Indianapolis, as his talent on the motorcycle and his ability to connect with fans both were very special. We extend our sincere sympathies to his family, team and fans."

Fellow MotoGP rider Héctor Barberá said: "I am in shock. We are bike riders and we are aware that there are risks involved with what we do, but we also know that every day our safety is looked after more and more by the organisers. These past few years have seen a huge amount of work done to try and make our job even safer. Despite this, there are moments in which misfortune can lead to tragedy -and we saw this happen today with Marco Simoncelli.”

“Today is another tough day for motorcycle racing. We have lost a great companion, and I will remember Marco as a great rival with whom had some fantastic battles in the past."

Team owner Jorge 'Aspar' Martínez, shared: "What has happened today is immensely sad. It should be said that every Friday before a Grand Prix, the Safety Commission convenes at 5pm with all the MotoGP riders to evaluate safety issues at all Grand Prix circuits. Marco lost the front end and attempted to save the crash, but unfortunately the inertia of the bike took him onto the inside of the corner just when Edwards and Valentino were passing. There was nothing that they could do to avoid him. Today is a tremendously sad day for the entire paddock and for those who love motorcycle racing."

Toni Elías tearfully stated in an interview: “There is nothing I can say…Marco was a unique person – but above all, he was a good guy.”

Karel Abraham and his team released a statement: "The Cardion AB Motoracing team extends its deepest condolences to the family, friends, and colleagues of Marco Simoncelli, who succumbed to injuries he received in the race at the Sepang International Circuit."

Many of Marco’s fellow MotoGP riders posted statements over Twitter remembering their fallen competitor.

Long time friend Valentino Rossi refrained from earlier interviews, to later publish via his Twitter account: "Sic for me was like a youngest brother. So strong on track and so sweet in the normal life. I will miss him a lot."
