A whole ‘nother 40 page topic of its own indeed….😳The arguments about running bikes in stretch long and far, personally l just rode my 390 Duke normally but carefully during the first 600 miles, then gradually increased the RPM after the first service.
I’m kinda with you ! You see / hear everything from a quite frankly ’laboured’ revs and silly slow speed method. To people doing a quick series of brisk runs; to create heat cycles and ‘bed the rings in’ 🤷♂️
I’m somewhere inbetween. Obviously fully warm before going over 4K for example: but pretty much drive as normal - varying the speed / revs. You don’t want the engine to Labour, or risk bore glaze.
Conversely you don’t want parts perhaps not fully mated to each other in an Engineering sense: unduly forced to excessive stresses at high RPM. ***Although this is probably less so in this modern age of high tolerance mass production. **Seeing lots of ‘swarf’ in the oil come first oil change is pretty much non existent these days…..
So: The couple of new vehicles I’ve had I’ve pretty much driven as normal when running in / for the first 3-500 miles. Just been careful to avoid the two fairly extreme ends of the Rev range. And then I’ve built it up a bit at a time from there…..
Tin hat on and ready for the oncoming flak 🤣
