YBR is better choice becuase DERBI and Wego has spare parts shortage and not bike is good for tour if it has spare parts issue..
YBR is under powered but will take you from point A to B and if gets damged or gos bad atleast you will have parts..
RX3 from zongshen comes in many flavor every vendor has different specs, the Road Prince RX3 is a very very promising motorcycle in very good price, becuase self import will be expensive.
