well I currently have and race a KX85. It is a beast, it has monster energy ghraphics, fmf fatty, v-force3 reeds, tag handlebars and a brand new top end. It hauls, but im getting a little big for it. im 14 5'6 130. Im thinking I should get a 250 four stroke but I dont really know! Im going to be racing arenacrosses and motocrosses around my local area. Im a pretty experienced rider. So 125 two stroke or 250 four stroke?
