Welcome to the motorcycling world! Today's cars continually start the engine - that's a huge draw. If you're going to leave your car sit more than a couple weeks then you should put your battery on a tender. Motorcyclists have been doing that for decades.

Yeah, I (not really) joke that everything on the hill gets plugged in. It makes life a lot easier.

Even with no idle draw, lead acid batteries self discharge over time. Life got way easier when I just accepted it, and now I've got a pile of 6V/12V battery tenders that go into just about everything (I have no shortage of 6V vehicles out here too). That and block heaters. The tractor and truck both appreciate them.

Why is that an issue for motorcycles?

Tiny batteries have less headroom against phantom drains. Also, most motorcycles aren't daily riders, so the problem is exacerbated.
