I read in an article they allow more air into the airbox
Spoke to a contact today who seems to have a connection in ducati/corse and has and sold 3-4 sets of 2013-14 wsbk systems and 2 wsbk tanks last year.
He told me today that his contact has told him that he has heard a price of 11,000 euro for the New Akro WSBK System.
