Cool video, but the guy on the 125 is taking four stroke lines and the guy on the 250f is taking 2 stroke lines, the guy on the tidler should be railing the outside of those turns to keep up his momentum rather than dropping to the inside and braking hard, then trying to accelerate out of the turn. Berms were built into tracks for two stroke MX bikes, their design was originated naturally, by dirt that would pile up on the outside of a turn from railing the crap out of it on a duece. They are not meant to be a decelleration ramp for fourstrokes to slow down up, then ramp down to build momentum. The state of modern MX is so backwards.
