I dont know what\'s he thinking but this guy play violen when riding the bike backwards. The quality of this dangerous picture seems pretty old, so it seems real that this stuntman really play a dangerous game.

This is one seriously wound moutain biker accident. This seems to be an extreme sport where a cyclist cycles down the very steep slope and unfortunately, his bicycle broke down caused him to injured himself badly.

Unlucky biker in this dirt bike try out fails two times on the ram. He succeed in jumping the third time though after failing 2 times hurtfully.

This is an old video clip on the web. Though, old clip, i think it is pretty meaningful. Never ever do evil things as it will turn back to you.

A cool clip showing many motobikers jump from the cliff and safely opens up their parachute to the bottom.

Awesome superbikerz!

dont leave ur children alone with your motorcycle's engine running!!! they can press the handle easily and booom!! watchout!!
