Guys,
I like it. Keep in mind the shape of bikes, especially in the liter class, is going to be based on racing and areodynamic performance. The the high tail and extended muffler under the seat is part of that package. Rear fairings and areo packages "behind the rider" are not allowed by any racing organization so the the rear shape of the new liter bikes is an attempt to get the smoothest air flow possible helping to reduce drag within the limits of the rules of the the FIM, AMA, etc. I'm enjoying the new shapes that are coming to market in attempt to gain an advantage on the track!
