Since the body is approximately a symmetrical wing section,it would be good to see a plan-view to estimate the trailing portions degree of truncation.
Baron Reinhard Koenig-Fachsenfeld and Dr.Wunibald I.Kamm researched truncated sections at Kamm's FKFS,attached to Stuttgart's Technical University.
The sections responded more favorably to the Jaray-form of truncation rather than the Koenig/Kamm form of truncation as far sa drag is concerned,although crosswind stability might be a driver for the optimum form.And ignorant as I am of motorcycle aerodynamics,I'd defer to Mr. Vetter.
An overhead view would help.
