Yes- similarly I have a friend who did over 17,000 miles on a KTM400EXC (admittedly the older RFS design) trail riding and traveling in both Spain and Morocco, with nothing but regular oil changes and a valve check once a year...

Even her current generation 400EXC has been to Spain and back with no problems - well, other than the limited comfort from the stock seat... that engine is sound too...
