Yingang did a real good job on their MINIS…I cannot see why they cannot make larger versions of this design.

If they have the resources then they could see about bringing the 249cc DOHC air cooled single Radial Four valve into production. That would be the engine that was in the GB250 Clubman.
The GB250 had a great engine 30hp…

The lines of the mini transferred to a larger model with a powerful 249cc air cooled engine.
