They could drop the prices on the 229cc versions to $2600.00, offer only black and then sell custom parts for them, it’s pretty obvious that the little misfit could be dolled up to look like a Vintage Mark3. I would consider setting up something in China to supply parts. For anything light weight, shipped direct. Fuel tanks are not that heavy. They could be custom painted and shipped direct.
If they want more sales everything has to come down in price, it’s been the case all along.
Also any offering needs global distribution partnering. That being feeding OEM business to the factory. Orders that increase simply because somebody else is buying the bikes and selling them under their brand in other global markets in alignment. Like Poland, Britain, France...
