On the question on the doors. I made the doors on a set of hinges so that I can easy take out the doors in case of heavy wind. They fit into the Luggage compartment.
The door closes with a magnet. I can knock the door open with my knee if needed for handling.
In practice I never took out the doors yet. With an additional rim on the nose of the streamline the side wind sensitivity became less.
The gearing of the Burgman should be altered to make better MPG.
In the gear train there is one set of gears that allows to be modified for lowering the rpm.
