Body plan taper and drag

I am always thinking about these aero shapes as would be applied to the top view of a motorcycle streamliner. The J form looks to be much better than a Kamm for a reasonable length.

Definitely! The Kamm chop costs us in quite a drag penalty.
The closer you can get it to the ideal,4:1 aspect ratio the better,dragwise



If there were stability issues,you might have to compromise on drag,if it couldn't be sorted out with other parameters
