What is the trade name for these connectors?

My Beta uses these connectors in many places and I'd like to find some plugs to cover open connectors, but unsure what the trade name is for these connectors. Anyone know?

Searching this forum I came up with the name: Furukawa, but they  aren't currently shown on their catalog. Maybe Yamaha bought a truck load of them years ago and used them on their bikes?  The '24 model doesn't even have those anymore.

Found it, it's called Molex.

The main issue with those connectors is that they are not waterproof. If you use them, it's a good idea to fill them with silicon grease.

These connectors are PITA to find. Couldn't locate them in like 10 stores. Got pissed and bought from eBay for insane markup, but I said I need, I buy, I ride.
