Nice story - in the Red Bull X-Fighters last year one of the new young guns coming through the ranks was Levi Sherwood, he was on a KX 250f - funnily enough although he did ok, I remember he lost out at some of the bigger tracks as the commontator said the 4 stroke struggled to pump out enough power to get him making the most of the track. It seemed the heavly and sluggish 4 stroke was holding him back.
This year he came out on a SX 250 2 stroke!! and hes looking really good, glad to see the 4 stroke fad in FMX isnt taking over, well it isnt in Red Bull X-Fighters, I've not even spotted one yet..
