Chinese motorcycle company pricing structure

Basic 125cc bike = 6000 RMB.

1. Any disk brakes add 2000 RMB per disk.
2. Any color other than red add 1000 RMB.
3. Double price if engine displacement doubles. (eg250cc will be price double 125cc)
4. Water cooling, add 2000 RMB.
5. Digital dash, add 2000 RMB.
6. Additional engine cylinders, add 2000 RMB per cylinder.
7. Oil filter add 1000 RMB.
8. Fuel injection add 3000RMB.

eg. Jialing JH600. 600cc so 24,000RMB, 2x disk brakes 4000 RMB, liquid cooling 2000 RMB plus efi at 3000 = 33,000 (near enough).

The problem being it seems to be they are just heavy on their calculators trying to figure out a price. What about component and build quality?
