What is that bar I see off most stunters bikes just below the tail light ? Is it just a plain bracket to hold the bike & protect the tail light or does it have more funciton (ie applying the rear break ?

yes I am fairly new to the stunting world, but thanks for asking

 

This is why :D

called a 12'o clock

 

That tough! Is the bike reseting on the bar ? Is the bar preventing you from flipping by keeping you on the good side of 12 o'clock ?

This grass hoppers got a lot of learning to do
