I just got a new bike with 0 km on it. I put 45km on it varying the speed and gears but keeping the rpm below 5-7k.
I am reading a lot on engine break ins and came across the "hard break in" method. Can others with more knowledge chime in and let me know which is the better one.

"Not one manufacturer recommends this method of mistreating a new engine."
Answer:
It's because they want you to never have a good seal between your piston rings and bore. They don't want you to have good wear patterns on your valve stems either. You will inevitably have the problems of blow by and excessive valve sooting which lowers horsepower in addition to lowering compression. Shortened spark plug life is also the result. The low rpm 1000 mile break ins are there to help manufacturers push more parts to the dealers for engine services and rebuilds. Since the oil is not changed early, abrasive metallic particulates stick around for way too long. Engine life is inevitably shortened because combustion and exhaust gas blow by, higher block and cylinder head operating temperatures, higher oil temperatures, high oil contamination rates leading to acidic/corrosive oil that shortens the life of brass and rubber parts, and impeded oil flow due to sludge. Most of those symptoms will go on plague the engine for the duration of its life because of poor piston ring seating. You can roll the odometer over twice if the engine and transmission is treated right. Going by the manufacturer will inevitably mean rebuild at or around 50,000 miles.
Method:
Turn bike on and idle for 1min. Once the bike is at operating temp.. step 2
find a place where you can go WOT in 2nd gear.. give it full throttle all the way up to rev limit,
then let it over-run back down to lower revs.. and repeat 10 times..
Change oil&filter..
The over-run seats the oil rings so your engine won't burn oil.

Is the above true? I want to do what is best for my new engine and its future. Any and all help is appreciated.
