The only time I noticed oil consumption was when I didn't torque the oil fill plug to correct spec. There's two oil filters, two oil screens, a drain plug, a fill plug, the two crank case covers, and they're all supposed to be to spec. How the motor was broken in makes a difference, how it's ridden... there are quite a few variables but bottom line, I agree, $11k dirt bikes shouldn't leak a drop and it sucks for those that are experiencing the issue.
