From the pre-review article
It's a CFMOTO 650i branded as WK. That's significant because who's going to be honouring the warranty on it? CFMOTO don't have any UK presence and good luck getting a tiny outfit like WK to eat any costs.
Even if you can get someone to do warranty work on this CFMOTO/WK, where are they going to get parts from? Hyosungs, for example, have been importing bikes for years (via E.P. Barrus) but parts supply remains pitiful - you'll be directed to salvage sites for any non consumable bits.
Good luck trying Kwak parts to see if they fit or can be fettled, it could be an expensive experiment.
Insurance is also going to be a pickle. If it's not on the main lists, then you won't be able to get comparison site quotes, and will end up paying more or spending more time searching for someone who will touch it.
All of this could be forgiven if it were A) significantly better than the competition (and it's not) or B) significantly cheaper.
But since you can get a Hyosung GT650 for the same £4200 price tag, why wouldn't you?
Nope, I'll be steering well clear until a lot of other mugs have wasted their money on these bikes. They might make an OK used buy (if they hold up to British winters, which I very much doubt) but that means they'll make a lousy new buy.
Never mind the sticker price, the cost of owning one is going to be higher than any Japanese or Korean branded commuter. You'd have to be certifiable to buy one new, and that's coming from someone who's taken perverse pleasure in buying Chinese branded bikes and the worst bike that Kawasaki every made (GPz 305). Even I have limits though, and £4200 is far too much to waste.
