The new Aprilia GP20 made its appearance at Malaysia today for testing and I do believe it has the biggest winglets I have seen since Ducati was forced to put their massive winglets on the shelf due to new winglet size rules a few years ago.

That's one fugly bike
Wait until the season starts and Aprilia put their Red,White, and Green paint on it. All the factories have black bikes during testing.
