Hi , new to this forum had a question I was hoping u could help with . I have a 1999 Yz 125 with blown motor. And just picked up a 2001 yz 250. Does anyone know what parts are interchangeable between those two bikes. Example can I swap the front shocks ? Or are the frames the same? Can I swap the swingarms ? What can I use off the 125? Are the radiators the same? Any help greatly appreciated .
