The piston might have been so hot that it melted flesh and skin to his arm so that it couldn't bleed.

Remember luke's hand getting cut off in Empire Strikes Back? Those lightsabers are hot stuff.

Poor guy... just another reason why I won't ride crotch rockets.

 

Ouch! That pretty much doesn't happen on crotch rockets. That only happens to race rockets, revving far past their design limits. Next time leave the rev limiter alone!

 

....

good luck to that guy.

 

if you actually look at the piece that flew out when it lands on the ground you can tell it's hard stuff like plastic or something (you can actually see that piece bouncing off the ground). i doubt that his hand got cut off. if it did you will see somekind of blood.

 

i origionally thought his hand was taken off but on watching the video several times, i looks as if :


the piston came out of the engine
hit the frame
hit the guys are from the underneath
glove was forved off by impact.


i think , major bruising / cuts on tthe underside of his arm

one lucky guy to still have his arm.

 

that's gonna leave a mark
