Hey look, actual smart people actually giving good advice! Are you guys aliens, or something? I don't see this sort of thing here on Earth.
Anyways...here is a copy of the new engine break-in methodology that I developed for myself after many hours of deep research on the topic. I have done the factory method (religiously followed what you will find in your TW owner's manual...) on a TW200, and I have done my research-driven method on two other new bikes. Although admittedly very much anecdotal, my experiences suggest that the latter is far better/more complete/more accurate than the former (in terms of overall power, oil consumption, etc.). Feel free to follow as much or as little of it as you wish LOL (some of it will be "too late" anyway), but yea here it is.
*Do several complete heat cycles (warm up the engine then let it cool completely over several hours) in the first couple of hundred miles; the very first heat cycle should simply be about 3 minutes of engine idling -- after that cycle, the rest should be around 10 to 15 minutes of riding.
*Always warm up the motor for a minute before riding; go easy on it while it's still cold (3 to 5 minutes of riding).
*During "normal" break-in riding, very frequently vary your throttle, engine RPM, speed, and gear selection (but don't use top gear too much); punctuate this about every 10 miles with a wide open (full throttle) blast up to about 90% of engine redline (max RPM) and then letting engine braking slow you back down to a low RPM (around 25% of redline); ideally, this should be in second or third gear (being mindful of speed limits...).
*Do not CONSISTENTLY/CONSTANTLY operate the vehicle at over 1/2 throttle for the first 600 miles; do not consistently/constantly operate the vehicle at over 2/3 throttle from 600 to 1,000 miles; note: still ensure frequent acceleration and deceleration under engine braking (just NOT normally at or near full throttle, except as noted^^).
*Change the engine oil and filter very early and very frequently during the first thousand miles -- at 0 miles (immediately after first heat cycle) and then at 25, 100, 250, 600, and 1,000 miles.
*Avoid running the engine for too long (not more than 10 or 15 minutes during the first few rides) without letting it cool down completely, especially during the first 250 miles.
*Be careful not to lug the engine too much during break-in: generally, keep the transmission a gear lower than you would normally use at any given speed and try to avoid riding on steeper hills.
