I've been looking for a ktm 50 mini adventure for my 6yo son. he now has a pw but i wanted somthing better for when we go to the track. found an add for a 07 ktm 50 mini. after seeing the pics he sent, I noticed the graphics said sx 50. now the bike is air cooled and has disk front brakes and drum rear. from what I've found on sites like bikez, all sx bikes are water cooled with disk brakes and all adventures are air cooled but have drums front and back. What bike is this? oh, and he said it has the 12mm carb. What I want is the tame power band of the adventure and no more than a 23"seat height, the disk is a plus. BTW, he wants $1,100 for it and said it has a fresh top end, foot brake conversion, new plastics and needs nothing. whatayathink.
