Sorry MJH, your arguments seem well constructed, however you are incorrect. There is already a Japanese EFI motorcycle being made in China, which isn't being successfully copied, the Jianshe Yamaha YBR250! The reason why it is hard to copy EFI systems is each needs to be tailored to the exact engine. Therefore there is no massive leap in imagination that would make it impossible for Sundiro Honda to manufacture the CBR250R in China, the VTR250 is much less likely. In fact I think an EFI version of the CBX250 Twister would be a better proposition, or an EFI version of the CBF250 as these bikes appear more basic. What does drive things being made in China is simple, sales. More likely export sales, if Honda needs cheap manufacturing capacity to supply demand, they will use Sundiro Honda.
