I hate to dig this back up, but ...

According to this guy that builds drag racing engines for a living, he says the motor is broken in within the first six miles. Coming from a guy that constantly tears down and rebuilds engines with the goal of maximum performance, it’s worth looking at. Maybe his materials and conditions are different? I am not an expert.

Sounds similar to the "motoman" method although I read it so long ago I don't know if he mentioned heat cycling or not.

I could add to my statement that I always give the engine enough time to fully build oil pressure/get it flowing through all passages. And I'm very easy on it til the coolant is over 100 if I even move prior to that. Then just drive when the heater starts blowing but won't really beat on it til the temp is over 160. Would be nice to monitor oil temp but we can't without an aftermarket sender/ gauge and I just don't want to do it. This is all just my personal routine, everybody's will differ. I did break in my Daytona 600 as stated by triumph and it seemed to do just fine also, but that trip ended badly with only about 10k or so on it.

How do you monitor engine temps? I hate how this car has no real info available. I want coolant/oil temps and I want oil pressure lol

You can monitor the coolant temp with ktuner (and I'm sure hondata as well) but as far as oil goes it's up to you to add it. I may do it at some point but since I haven't yet odds are I never will...

As someone who writes and edits legal documents for a living, I absolutely guarantee you that Honda could properly break in every single engine at the factory and they are still going to write in the manual that you have to properly break in the engine when you get the vehicle. It's a matter of minimizing liability, not an indication of engineering quality. It's just like the note that says you should only use Honda branded fluids. They aren't trying to get a few extra bucks off of you as much as avoid a lawsuit if you put your cousin Jimmy's leftover bacon grease in your transmission and try to blame them for your lack of knowledge.

In short: the fact that the manual lists engine break-in as the owner's responsibility gives us absolutely no knowledge as to the actual necessity of that process.

I've been told that the break in warnings especially for things like high performance bikes/atvs and stuff are to attempt to force you to get comfortable on the machine and at least aquire SOME skills before you go crazy so you have a smaller chance of hurting yourself.

Building vs. assembly line manufacturing are two very different approaches. Micro-wear continues well past the specified break-in period. But it's far more sensitive on a production motor that will see triple to quadruple the service life over a manually built, high performance motor.

Bacon grease FTW! Been using it for years in the engine. And everyone loves the exhaust smell!

I think I was gentle on mine for the first 1500-3000KM I'd put on it, at 20K now and she LOVES +9 PSI ;) Told myself I'd keep it stock and baby it forever but that changed rather quick!!! I'd be nice to it for a bit to properly break in the clutch and all but after that, enjoy it!!

The author used a "leak down" to measure how well the cylinder was sealed using different breakin methods.

High performance powertrains have a much wider ring gap to account for the increased flex/heat transfer. Acceptable psi loss is much larger over a typical production motor.

I suspect the author's definition of "sealed" is much different than what a typical automaker manufactures to. But I'd be interested to see his testing data get a better idea.
