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 altlurssheim near HockenHeim
Rolf?

The Citroen engine looks different than the RO80 engine.
