As noted, the YBR is Chinese
You mean Chinese-branded. It's not the same thing, and neither are all Chinese-branded bikes. Lexmoto, for example, sell bikes from 4 or 5 different manufacturers, and they're not all the same quality. The expensive ones are not necessarily better than the cheaper ones either.
I've had two Chinese branded bikes, a Huoniao HN125-8, actually made by Dihao and now sold as the Lexmoto Vixen, and a Lifan/Skygo LF250-B, essentially a nut-and-bolt copy of the Virago 250.
They were both reasonable for the money, both had some issues which were fairly cheaply and easily rectified, and I don't really have any complaints, especially at the price. A used Japanese branded bike for the same money makes more sense because it won't depreciate, but you're likely going to have to replace parts or do some work on either bike. Insurance remains a pain in the arse, but they're not totally unreasonable choices.
On bigger bikes, the "CFMOTO 650NK" is now on sale in the UK, re-branded (as always) as a "WK Bikes 650i". It's a copy of the Kawasaki ER6-n, with all the usual muddy waters about whether it's a clone or whether the Kwak or its parts is actually coming out of the same factory at a higher price.
The UK price on it is way too high - they're asking Hyosung money - and you'd be a chump to buy it new. But if anyone is brave/daft enough to do so, they might make an interesting option a couple of years down the line, after we can see how they cope with UK winters.
