Very educational reference figures Dances, Best is a combo of small frontal area plus streamlining features. If ya dig in on some of the Norton full race fairing you will find statement that the front around engine was left flat to allow air to pile up to allow some stream lining of 'bluff' shape. Aim of exhaust plume is also worth some sucking drag reduction. Who know about the VW vs 924 testing results w/o a roll down test and changing stuff to see what matters, beside tire rolling drag. To me the sideways stream lining is more important than bee line designs, which is where the dust bins had real issues to avoid. Peel suffered side ways wind / ground effect lift/drop issues and d/t her incredible isolation, [as in unbelievable separation meaning] of every force of air and surface texture, I know where the forces struck the most and what/where they ended up begin felt in handling upsets, so I'll start with fork eddies lessening, then venting in middle and pressure build at rear, one side at a time when leaned good. I cut my mc teeth on too low a bike to lean, so know both the bee line sprinting speed advantages and its handling down sides. Peel will have it both ways to go faster and slow faster too i hope with ass end squated. On the fly spring rate changes too. Peel never got completely liffed off surface by air gusts, just the front/forks that would wiggle/jggle through frame but my SuVee has twice lifted both tires/whole bike up and out at the tangent on pitching into down hill sweepers with some strom winds left, never ever again I assure you as only lack of oncomming at the time allowed room to recover. Part of my motto Throw Yourself at the Ground and Miss" is d/t the air compression rebound lifting her back up w/o my effort. Its unworldly sensation and one of the few unpredicable things her flex-ness helps take up to make use of.
