Seems to me that Benyco would be the place to sell the café model.
Romet is selling the heck out of their Ogar and getting a slot in the Benyco line would be the best start for the Fuego.
If they have the rights to selling it under the brand Levis, which will be inevitably equated with the jeans regardless to the actual history of the Levis Motorcycle Company, which ended in 1940, outside of this generation. They should sell them as a sub brand and with the many add on custom parts. I would not be attracted by the Levis brand the significance of the Brand is lost when it is made in China and without any material connection. That being a genuine resurrecting of old designs opposed to just a resurrection of it for marketing. It could repel as many as if not more then it attracts, the connotations run the spectrum within the market without real legitimate market surveys I would not be sure if a brand or model name is positive or negative. For example to me Fuego is a Renault that was a piece of crap that looked like a weasel. Also google it what comes up, Fire, not sure if even a Spanish speaker would be attracted or would feel it was contrived? Neutrality is best and codes and key words best that bring up the item in HTML best.
So it could be offered through Benyco and best would be for less than the Romet and with more options. Which would be a base under 1200 Euro and options to doll it up or make it your own. If you think about that it could be a branded website linked to through Benyco with a build your bike function. In that you can build the profit.
