Shady dealers will swap the good Yuasa with a rando 'Extreme Powersports!' no-name, so that they can rape someone who brought their bike in for service by selling that 'new Yuasa OEM factory-original' battery (that the dealer didn't have to supply nearly the Cost of Goods Sold for). Great way to improve margins without it hitting your books.
I have such an 'Extreem Powersports, Dude!' battery in my bike: the battery it came with as a 2017 leftover (and note the stripped Phillips head in the ground terminal. I also found the RH seat bolt was cross-threaded and only partially in the hole and had to chase the threads with a tap).
