Used 10 fin right head to suit (259) R850R/RS/S/GS and R1100R/RS/S/GS models up to 01/1994. Later models have nine fins.

All fins are in good order as are the threads.

Comes complete as shown in the photos with valves, rockers, cams, and cam sprocket.

Cams and lobes are in good condition without any scoring as is the face of the head.

Will need a good clean.
