MOTOCROSS star Jayden Archer has died at the age of 27 while attempting a dangerous trick.
The Australian rider shot to fame when he became the first motocross biker to land a triple backflip in a competition.
Archer - nicknamed "Jayo" - was attempting the stunt during a training session in Melbourne when it went wrong on Wednesday.
Nitro Circus, an actions sports group, hailed Archer as the "epitome of passion" in a tribute.
It read: "The Nitro Circus family is mourning the loss of Jayo Archer.

"Jayo was the epitome of passion, hard work and determination.
"He pushed what was possible on a dirt bike to heights never seen before.
"A positive influence to those around him. And above all else, a great human being and friend to us all."
Archer hit headlines in 2022 when he landed the first-ever freestyle motocross triple backflip during a contest at the Nitro World Games in Brisbane.
As he celebrated, he proposed to his girlfriend Beth King as crowds cheered.
They were due to marry later this year.
After landing the trick, he said: "I cannot describe this feeling.
"This is so much more than a trick to me. I’ve dedicated my entire life the last three years to this moment.
"There were a lot of obstacles and broken bones and knockouts, and I would do it 100 times over to relive that moment again."
It is understood he was planning to attempt a world-first quadruple backflip before his death.

Archer performed his first show back in 2012 and went on to win two X Games medals - including one in California last year.
In a tribute on Instragram, Nitro Circus founder Travis Pastrana wrote: " Thank you for the memories friend.
"Thank you for being such a great human and positive role model for all of us."
According to official records, two motorbike riders have landed a triple backflip - but not during a competition.
