the new 500 exc (no FI 450EXC on the KTM usa website yet) has 1.5qt oil capacity, 100hr valve adjustments (non-race conditions) and oil changes every 15hr. in my mind that's weekend adv bike territory. im not sure anyone is ready to pay what it would cost to get KTM race bike with license plate performance with true adv/street bike service intervals. im not even sure you could do it?
I don't know how to ride a bike...yet
