There are 1/10th model kits that have motorcycle riders and I have a wrestling action figure that size. A better solution would be to have someone take a picture of yourself on your bike with meter stick visible to help scale. I am just under 6 ft. and my inseam is 31 in. Make a figure template with movable joints if you like to compare positions.
The Template C profile was, I believe, developed for cars which are at least twice as wide a motorcycle and dates prior to WWII. The Morelli shape is based on more modern research. For a café style motorcycle the weight is forward say 55/45%. The Rifle Yamaha shell and the AeroTech Bonneville fairings used by Fred Hayes are designed for such a riding position. For a cruiser, scooter, or a Feet Forward design the CoP needs to be more aft and front lift is more of an issue. Rather than champion one form over another I suggest each have limits and benefits that are applied to a total design.
I am using a scooter since that is what I have: Honda 50cc 2 stroke. I will experiment with aero bars on the handle bars to lower the profile height. The profiles are scalable and can be adapted to local conditions by changing the angle of attack or adding a small vertical stabilizer. I live in a river valley and sendler lives on a lake plain so weather patterns are different. How we carry luggage can also play a part.
