Clarifications:
* the width will be 1/2 body height, as measured by subtracting the ground clearance from the overall height?
..See
Permalink #3 in the
RH Barnard on templates thread.
* ' 2-x the taper' I don't have a clue as to what that means.
..Taper on both sides
* and I still need you to define what you mean by '40% truncation '
..It's a line on your graph from 2009
* and what goes behind the b*tt trumpet ?
..Maybe half the back tire?
The purported body would be an asymmetrical ellipsoid, front to back and top to bottom , but not side to side. Cross section could be half circular, but superelliptical might give better cross-wind performance.
Rotate this back to get the shark body profile. Tires are 145-15.
