Yes I am guessing. Theory based on the vane hydraulic pumps that do not
have gearing like the Wankel designed rotary engines. The motor cycle
engine MAY have silicone nitride seals, but I do not know. Lots of Mazda
engines built plus the Audi and Citreon engines and then the Mazda copy
Russian engines. How many of these motor cycle engines are in use?

Dale,
Sorry to say but Audi did not build Wankel engine nor did Citroen. Perhaps
you refer to NSU who made an agreement with Citroen for a joint
development. Citroen builds the car, NSU the Engine. Motorcycles were not
in these talks, however Fichtel and Sachs did work on Motorcycles as well
as the Brits.
Perhaps the Russians build Motorcycles too?
As of late, the Russians are also developing the same engine Rahael Morgado
(MYT) is proposing, at least that is what they have announced.

Have you every been to the Wankel Museum in Altlussheim near HockenHeim
Rolf?
The Citroen engine looks different than the RO80 engine.
Paul Lamar
Indeed, I have been in Altlussheim. However, not long enough.The person I
went with was not an engineering type fellow. :)
The engine for the Citroen was an NSU supply. Yes, different to the RO80.
The following site provides a lot of info about the Wankel development in
general and by NSU as well. However its in German. It is an impressive
list. NSU was really active and believed in its future.
I also had ones a discussion with Dr, Froede, the key motor (pardon the
pun) behind it . At NSU the terms was coined "Kraft durch Froede", which is
a synonym to the term of the third Reich "Kraft durch Freude" where Adolf
wanted population growth and urged the every woman to have a child for the
"Fueher" (Leader) 'Freude' means joy / pleasure. 'Kraft' means strength.

The page of the site that is open now is a list of the various developments
til 1975. See items 23 and 36 engines for Citroen. I am not sure but I
think that the Comotor items 33 and 34 of 1970 were also for Citroen. By
that time I had already left.
