    Aprilia, Rotax and V990

    Guys (and gals),

    After reading the Rotax website, I got confused about the real "ownership" of the Aprilia V990 engine. Yes, I know that Rotax builts these engines, but I was under the impression that they were designed by Aprilia or Aprilia/Rotax and built by Rotax. That was why the V990 engines were used only on Aprilia bikes. Also, I thought the patented counter balance design was from Aprilia.

    The Rotax website site lead me to believe that the V990 is Rotax, although they show a pic of an Aprilia Mille (italian for thousand).

    Thanks for any clarification. Just for my own information, no more than that.

    I've been to Rotax's website also. My impression was that they were showing the type of technologies and services they offer and were using Aprilia as an example. You can not by the engine directly from Rotax. You have to buy it from Aprilia. Also I believe at one point KTM wanted to use the 990 engine in their Duke but Aprilia wouldn't let them. From what I understand the engine development was collaboration between Rotax(building) and Aprilia(design).

    The V60 engine was designed in house at aprilia. Project leader on the engine development team was Mariano Fioravanzo. Giorgio Del Ton was chief engine designer. Two patents came out of the effort. AVDC, Anti-Vibration Double Countershaft and PPC, Pneumatic Power Clutch.

    If you search those two names you will find more.

    EDIT: I seem to be in error with some of my information here.

    Thanks to the efforts of Bikoman he has found the patents for both the PPC and the AVDC and they originated from within Rotax. Three Austrian engineers are responsible. Not an Italian in sight. Thank you very much for clearing that up. I seem to be guilty of believing everything I read in the motorcycling press and certain big wigs at aprilia are guilty of over emphasizing their role in designing the V60 engine.


    PPC Patent


    AVDC Patent

    I can't remember where I read it but I thought Cosworth engineering worked closely with Aprilia on the design of the engine. Afterall what would a bike assembler know about designing a high performance engine. Afterall it's a very complex thing to design and get right.

    Cosworth designed the engine of the Mille SP for WSB homologation as well as the engine for the RS3 Cube in MotoGP.

    I think the engine was designed by Aprilia, but was built by Rotax. I also think that Mariano Fioravanzo help design KTM's LC8 990 engine.
