have you guys everheard of seat bumping, theres a tight private sx track by my house and thats what everybody does their, like you sit untill after you leave the lip then you just stand up and bring the bike forward, it looks bitchin, once i get my 250 ill get a helmet cam of the place, their are some big doubles there, you gotta be on ur game to hit them
Seat bouncing is a fairly advanced technique, make sure to start small. TWMX had this as one of their Tuesday Tips, nice read. http://motocross.transworld.net/1000079851/features/tuesday-tip-seat-bouncing/
