Greetings I am currently riding a 98 wr400f, never had a days problem, always started first time, never broken anything that wasnt my fault. I am now looking at buying a 2001 KTM 520 EXC. Rode a friends some time back, cant beat that performance. I have heard many stories about broken motors and expensive parts. Any advice to a first time KTM owner, is this a do or a dont.
