A video of a racing competition has gone viral after two riders were caught on camera engaging in dirty tricks.
The clip, uploaded to Imgur, shows a large crowd assembled to watch the motorcycle race.
Stood behind barriers, they watch as two bikes ride around a corner of the track close together.
But one of the competitors decides to ruin any chance of his rival winning, and slams his bike into his side, knocking the rival off.
The crowd looks shocked as the fallen cyclist rolls off his bike, and the rider who pushed him off rides on without looking back.
But he hadn’t counted on the anger of his rival, who decided to get his revenge.
The video clip cuts to show the rider in green coming back around the track again, this time without any others riding near him.
As he turns the corner, the rider he knocked off can be seen standing to one side holding a heavy white sack.

He throws the sack as hard as he can, watching as it lands under the front wheel of the rider who ruined his chances on the track.
Clearly realising what is going on, the rider in green tries to swerve to avoid the sack – but he isn’t fast enough, and he is knocked off his bike, any chances of winning going with him.
The clip has received over 136,000 views since it was uploaded.
Commenters can’t believe the behaviour of either rider, and rushed to share their thoughts.

One said: “Seriously though, he could have hurt lots of people, he got what was coming.”
Another said: “I kinda see two a*******. One is bigger than the other. But still.”
And another noted: “You have both become vilified.”
The video of the two fighting motorcyclists is not the only one to go viral this week – a clip of a man nearly being killed by a falling block of ice has swept the web.
