| In July 2007 we decided to make a complete rebuild of the KTM 520 EXC, since the bike has 6 years and the engine needed to be repaired we took the oportunity to restore it. You can check the evolution of the KTM in the photos bellow, just pass the mouse over the thumbnails to see the 1:1 ones.
This section will be updated many times as long as the bike evolves, so feel free to check it out once in a while.
