Hondas never needed running in so not worth it
Interesting many new cars these days are the same.
An aquantance of mine "Roy" was a metalurgist for the NCB many years ago moving eventually to a firm called Lubrizol in Hazelwood, Derbyshire as a research chemist before he retired some 20 odd years ago.
https://www.lubrizol.com/Lubricant-and-Fuel-Additives Lubrisol have diversified hugely since I was a teenager but a core part of their business was / is destruction testing etc of car engines & components. Back in the 1960's they would lend out cars to people who worked in the car trade over the weekends with free petrol provided they covered at least 200 miles between the Friday and the following Monday. I digress -
Roy used to drive a Triumph 2500 TC that he purchased from new - he painstakingly ran the engine in for 20K miles it would have been a P regd motor. When he was telling me this feat of restraint he went on to explain that he had owned the car for over 15 years - it by then had topped 200K miles - it never burnt oil and was as quiet as a mouse! Sadly the bodywork did not bode as well so he eventually got rid.
I know machine finishes are much better today but he always argued that if you even over revved a new engine just once you could undo all the previous good as at a molecular level you were chopping off the peaks of the metal structures where two surfaces were in moving contact.
