The rotation of the damper body with respect to the bike is less but what is more important is it's rotation with respect to the steering. If you compare this with Vincent's photos, you can see that the damper body remains almost parallel to the steering stem so is more efficient in translating the rotation of the steering into the linear motion required to operate the damper rod.
The length and offset of the damper actuating levers used on Vincent's, mine and Norman's version is determined by the damper stroke in order to get equal travel lock to lock and have the steering stops prevent movement before the damper stroke is used up. This is evident from the picture showing the damper stop in the side car mount where a "static"lever is applied to the damper rod.
When I decided to source a centre body pivot, I found many damper mounting kits for a wide range of modern bikes using these dampers. The mounting details vary but all had actuating levers on the damper rod with the damper body pivoted on the frame so I decided not to re invent the wheel.
I have noticed that with the damper, the steering is lighter than with the friction damper especially at low speed so I wouldn't use the original damper with the new one. I shortened the original damper rod so I could put the original back for appearance and kept all the original bits for a future owner when I join great VOC in the sky.
