what follows is not necessarily a practical idea, just an idea

1. Add an electric motor to the front wheel.
2. As soon as the bike comes to a stop, snap the front wheel 90 degrees (bmx style)
3. use balancing sensing logic (like segway) on the front wheel motor to keep the bike upright.

So you could still "steer" while at a stop, could even move the front end in an entire circle by leaning, but the bike would stay upright.

And of course a motor on the front wheel means hybrid possibilities, and balancing means you can pedal recharge at the stoplights, yadda yadda...

Indeed a creative mind can also create unpractial idees. Maybe an electric drive with software could open and close bomb bay doors below and above a certain speed.

I don't think the Burgman's front wheel will turn 90 degrees. Full-lock turn is probably enough, but I'm just saying.

What's wrong with the bomb-bay doors? Or retractable landing gear? I saw a couple of Ecomobiles in Pigeon Forge a few years ago, the landing gear was what really grabbed my attention. They snapped down, snapped back up. Really cool.

FYI, I liked the foot actuated bombay doors too, keeps the wind out and very uncomplicated

If somebody is interested in a discussion on which size engine to take for a streamliner, than read this about a Kawasaki FE test

Theory of the petrol engine

For the near future I can change the engine capacity of the Burgman. Three different strokes and three differernt bores can be inter exchanged in a 400 bloc.
Stroke 60mm of the 250CC with bore 73mm , stroke 71.2 mm of the 385CC bore 83 or stroke 77.6 mm of the 400CC with bore 81mm. Which would give the best result?
Assume the the gearing ratio if free.(I have my own gear cutter for that.)

least bore with longest stroke is my guess. Add a couple more neutral detents while it is apart too (between the top gears).

That would give a 325 cc with 73 bore and 77.6 stroke or should a longer stroke bring more assuming rev`s go down further. Probally a longer stroke can be accomodated in the crankcase as well. Honda uses in some models an even smaller bore to stroke ratio for the best FE.

It might have 90 degrees total, but it won't turn 90 degrees to one side. So, 45 degrees left or right of center?

Starting with the Burgman project I considered a three wheeler like the Paggio (two front wheels) . Also the auto moto will give the same type of bike. I choose the Burgman because I assume that the full streamlining will be easier with two than with three wheels (ending with lower Cd) , but maybe I am wrong. But ofcourse with two wheels the bomb bay doors etc. are a complication.
