Don't see why it should be machine specific for motorcycles. The only possibly relevant variable I can think of would be whether they have sliding tappets, (I'd guess the KTR does) in which case you want an oil with a lot of zinc in it, which rules out most recent spec motor oils.
Your question is controversial and a matter for theological debate, the main schism being between the hard and soft/factory break in factions.
Another relatively minor conflict is a tis/tisn't over synthetic oil as a break in lubricant.
This guy is the Messiah with the hard break-in mantra. IIRC (havn't looked into this for a long time) he's at least partly full of shit, but that doesn't mean he's wrong on this issue.
Its been discussed on here in various threads, e.g.:-http://forumosa.com/taiwan/viewtopic.ph ... n#p1004130
Re oil, since you should be changing it especially frequently in the initial stages, I'd use the oldest spec (for the zinc) mineral oil you can find. For me, in the summer, that would probably mean the CPC straight 40W stuff, but IIRC they also do a fairly high weight-range relatively old-spec (15/40W SJ I think. ) multigrade.
If you can find SH that'd be better, but I doubt its still available. In fact I wouldn't be surprised if the SJ stuff doesn't disappear soon, since its already retro/obsolete.

EDIT : Oh, and no "lugging". i.e keep the revs up, and don't change up too soon. Apologies if this is obvious. ENDEDIT
