Welcome aboard! I'm not sure exactly what you are looking for but one of the members here bought a Boomcat 125cc. First thing that came to my mind is that this would be a really good bike for the back of an RV. Simple design,light weight, with minimal plastics to break, and street legal.Haven't seen an update from him lately though.
