RenthalC241 R1 Works 420-Pitch 120-Links Chain

My son has a honda 2007 crf70. will this chain fit? renthal website says this is the correct chain for the bike but amazon says it does not fit?

will this fit a 2019 grom with 14t and 36t sprockets?

My son has a 2015 crf 150r. The dealership said the size chain needed is a 420 with 120 links. However, this one says it doesn't fit?

Is their o ring or non o ring? Looking to put on 2014 grom
