Keeway is of lesser quality than Suzuki. But it is not too unreliable. Not dangerous.
The rest? So-so.
I chose 10 year old Japanese over new Chinese, but a colleague has been riding his Keeway 150cc no problems for some 4-5 years now.
Besides, Chinese choose to sell low quality for cheap. They can make really good stuff, but that stuff would not be cheap enough to lure people into buying them. Who would buy a decent Chinese 600 cc for some 5000 euros, if they can go for a 6000 euro Suzuki, for example. I think China is what Japan was some 50 years ago. Nobody wanted Japanese crap in those days, did they? :/
Bloody spill chicker is conplaining a gain!
