so did you not read my post that you replied to?
Never mentioned a thing advocating lugging so dont know why thats a point
As far as wot do you not realize that operating temp is synonymous with fully warmed up ?????
so again, when fully warmed up at normal operating temperatures, there is nothing preventing wot during break in in the manual.
it is clearly implied since they specifically say you cant go wot prior to it warming up.

You said there is nothing in the manual about heavily loading the engine which lugging is just that. So what did I miss? Never said you advocated anything.
You also said there was no mention of throttle position in the manual related to break in. I pointed out the WOT statement but also lugging requires 3/4 to full throttle when in too high a gear (or from low rpm).

I just changed the oil at 6k after doing the 1k first change to synthetic, so 5k on this oil. The oil was the cleanest I’ve ever seen on any bike I’ve owned after 5k miles. It was not black at all. More of a dark honey color - like you’d expect to see after just 1k miles. I’m guessing I have a great ring seal and no blow by. So here’s what I did on break in. 2 miles on the bike when I test rode it at the dealer on a 20 mile route with rpms up to 3k and modest acceleration. On the 80 mile ride home, I accelerated hard at 1/2 to 3/4 throttle from 2500 to 3500 rpm ONCE EVERY MILE, and then decelerated. I did the hard acceleration/deceleration in 2nd, 3rd, and 4th gears. By the time I got home, I had done the acceleration/deceleration cycle 80 times.

I've bought 3 new M8's, 2018 Heritage 114, 2019 Street Glide Special, 2020 Street Glide Special.
I broke all 3 in hard not worrying about RPM's. I did not run constant speeds until I had 1,000 miles on each but, did not baby them either.
Had no issues with any of them after putting many 1,000's of miles on each.
YMMV

if youre in 5th or 6th gear cruising at 3k rpms and you crack the throttle wide open, that is considered lugging?? Either way, I was talking about high loads within the normal designed range.
The way I always looked at it, there is high load similar to what happens when racing, and there is overload where the engine is clearly struggling/shaking, etc.

Its your bike, do what you want. You saw the guidance on here, not really any different than what MOCO had to say. One thing about America..in buying a new HD you bought and paid for hundreds of hours of engineering expertise specific to that bike and motor. Want to ignore it? GO FOR IT!
below is an excerpt from my wifes manual of her car, she drives a hemi
Drive moderately during the first 300 mi (500 km). After the initial 60 mi (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in. However, wide-open throttle acceleration in low gear can be detrimental and should be avoided.
now although it doesnt say to drag race out of the dealership and tap the rev limit at each shift, it does actually recommend full throttle!!!
it is concepts like this that make me believe there is a value to running it on the hard side, but not stupid or abusive.
so if thats what mopar is willing to state on a mass produced vehicle, just imagine whatd theyd really like to have you do, but cant say.

Not from me, because that's the procedure I've used on any new bike or car for the last 40 years

Certainly not me. After driving for over 50 years I've never owned a mopar product, so I am not qualified. But I do have a question. Is that the mopar owned by Chrysler Corp when they were US based, or is it the mopar owned by Mercedes Benz, or is it the mopar now owned by Fiat? Just askin'. Don't take it the wrong way, the Italians make great pizza!
