My take: When I was looking for a donor bike I had considered the airhead BMW. The area in front of the wheel just aft of where the drive shaft exits looked like enough room for a PMG pancake motor (but I never measured), the main issue would have been if the rotation was correct for the PMG-132 and securing the drive shaft with a bearing so you could use a sprocket. I was (am) sold on PMG for EMC. Over 1000 trouble free miles so far using a jackshaft so the PMG motor rotates properly. Cheers. Jeff (BTW - my ICE bike is BMW)
