I know I've read here that the tall SDG fitment is horrible and the GUTS tall foam is rediculously high. For what it's worth Motoseat makes a foam that is a 1/2" higher than stock at the lowest part, which sounds just about right. Had anyone here tried one? Also, TH1NK technologies makes super lightweight foams for the factory teams that save over 1lb compared to stock. They make them for current 250f/450's only, but they are willing to produce them for our cr125/250s if they can get 4 buyers to commit. Apparently the mold process is quite pricey. Anybody interested in a group buy of 4+ To get them into production?
