Typically Chinese designs are produced by more than one factory, but the stories I read about one of these Honda Joker clones on an American forum was literally horrifying. In one reported case, the customer got less than a mile down the road on his brand new scoot before the engine literally blew up, he then waited 6 weeks for "his dealer or distributor" to replace the engine. That forum was extremely active with numerous horror stories.
It's that sort of horror story that makes me stick to brand names with adequate support and spare parts back-up from the manufacturer / distributor and dealers for any big ticket item.
