ok... lets analize this...
The only things you need for that are: Bald tires... they probly are by the looks of the place... and some oil... by the looks of the kid he probly has some of that too
Apparently its been a long time since someone has ridden a bike. Back when me and all of my friend used to ride street and dirt we used to do that all the time. Its all about front brake control and weight transfer... also slippery pavment helps.
BTW gearing also helps, fo sample its easier to do a burnout in 1st gear then in 5th. Gotta love them 12 speed bikes.
