My little one has just turned 4 and got a PW50 for his birthday. He has however decided he likes to jump a lot - see pics http://s1224.photobucket.com/albums/ee372/Rachael_Barwick/?action=view¤t=00021.mp4 The poor PW's suspension does not seem to be holding out for this and we are thinking of upgrading to a KTM 50 shortly as he wants to start racing as well! We have however heard that they are not going to be selling the KTM50 in Australia for much longer - does anybody else know about this? Also, what is the difference between a KTM SX and KTM mini adventurer. Thanks!!
