i have bought and raced a ktm 250 exc every year since 98. i race in the pro class at local harescrambles and in the a250 class at the gncc races. im upset the exc didnt get the make over like the sx(2003 bikes.) i was wondering what you think of converting the sx (18in wheel,flywheel,gaurds,revalve,tank,ect) for pro level offroad racing? new frame,engine plastic looks real good! or just get the 03 exc (same ol same ol) :think:
