Paul,

      Have you been following the Norton NRV500/700 motorcycle news.
    They ran
      173mph at Bonneville in 2010 with this engine.

      I can't seem to find any specs on the engine anywhere.

   This link may help. At the very bottom there is a little scoop about the
   Norton.
   One chamber has 588 cc as the name implies. A larger 700 cc chamber size
   is being planned.

Rolf,

Did you mean to state that the 588 was a 2-rotor?  According to the
link, the 588 is a 2-rotor.

"Norton has used a Wankel engine in several models including the F1, F1
Sports, RC588, RCW588, NRS588, most notably Steve Hislop riding to
various victories on Norton's F1 in the TT in 1992. *Norton now makes a
588cc twin-rotor model called the NRV588* and is in the process of
making a 700cc version called the NRV700."
