beyond my capabilities i'm afraid, but if ever an aprillia chassis with no body were to turn up then maybe, i was looking at buying an aprillia chassis earlier this year but unfortunatly it sold while i was trying to do a deal, never mind, aprilia engine, well we've done alot of measuring between the truck and 1 of our aprilias, the width isn't a problem + the ardea enginebay is actually taller than the aprilia! length wise its alot shorter , we are going to try a bare crank case head and rocker cover in situe to see if we stand a chance without serious modifications to the body, will keep you posted
