I agree it's all-but-impossible to break it in as the manual says. The two major streets here are 45 mph...heavily-traveled 45-mph. You'll get run over by a bro-dozer rolling coal if you are any slower.
And 45 mph is 7000 on the tach.
It's not a good situation. Remember, a machine is not muscle. You don't build up strength in a machine by running it hard. And going easy on it lessens the chances of a bearing not wearing in, and then failing - in the first thousand miles. Or having rings not seat. Those problems are not nearly as common as they were fifty years ago...when my old man learned the hard way, and then later drilled the lessons into me with the new family car when I was a kid with a license....but they can happen.
I've tried to vary the speed - that's easy enough, those 45-mph stretches have stoplights. Tried to stay off full-throttle - not so easy since we have some long upgrades on some city streets here. WOT in third gear, is required; or else hitting the rev limiter in second.
Oil change at 250 - unplanned but it needed it. Synoil in there now.
I have 590 miles on it. Wish I had comfort in opening it up. From having broken in a TW, years ago, I know top speed may well increase quite a bit...which tells me that at least the TW engine, probably this one, too, is tight when new. But I'll just probably wait a few more miles...1000 is a good round number. I'll get there, since in this temperate small town, I can ride nearly all the time, on my regular business. And it's easier in traffic than taking a cage.
