Disappointing assembly problem and a question (at very end)

I went to do my first oil change yesterday at 600 miles. Armed with new oil, a new Yamaha filter, a new crush washer, and even a new drain plug (just in case the hex socket wasn't up to the torque), I looked forward to a much simpler oil change than I've been doing the last several years on my KTM 950. The drain plug came out cleanly and easily and the bulk of the oil was soon in the pan. Things got disconcerting when I went to remove the filter.

I put the filter socket on the filter and tried to loosen it. It didn't budge. After ensuring the filter socket was well-seated on the filter, I leaned into it. That only rounded the flats on the filter. The filter didn't budge.

With a curse and a groan, I grabbed a hammer and a screwdriver and drove the screwdriver in one side of the filter and out the other. I then put a pair of vice grips on the end of the screwdriver for leverage and leaned into that, which brought a moment of joy as I felt it give. Sadly, my joy was short-lived; the screwdriver had just torn the filter casing some. The filter hadn't budged.

After more cursing, I went down to Napa and bought a strap-type filter wrench. I tried that alone and in conjunction with the screwdriver through the filter. It didn't budge.

After lots more cursing and some Internet searching for ideas, I lined the strap wrench with sandpaper to give it better bite on the filter. Leaning hard on the filter wrench did nothing. Leaning hard on the filter wrench while whacking the handle with a hammer worked. It budged! 

Wiping away tears of joy, I readied my hammer for what I figured would be the whack that freed the filter once and for all. But it just budged. Another dozen or so furious blows moved the filter about 1/4 turn. Obviously, I kept at it. After no fewer than 100 blows -- 4 of which pinched the web of my hand between the hammer and the handle of the filter wrench, the filter had spun through two full turns and finally came off easily.

This is what the filter looked like:



Keen eyes will have noticed that something is amiss with those threads. At this point, I was disappointed but less than surprised to see that the mounting threads looked like this:



I took delivery of my bike two weeks ago with 1 mile on the odometer. Obviously, this is a factory assembly problem, which is very disappointing.

The only silver lining is that it looks like the filter mounting fitting is removable, which brings me to my question: Would any special tools or techniques be required to remove or replace this fitting? The service manual calls this this an "Oil Filter Cartridge Union Bolt" and only mentions that it should be torqued (with engine oil) to 70 N-m.
