Good used rear short stub drive shaft 20 spline to suit K1 09/1988 - 08/1993; K100RS 16v 09/1989; - 08/1992 K1100LT; K1100RS.
Later models had a 17 spline shaft going into the final drive.
This came from a K1100RS with 85,000 ks. on it. Unfinished project. The uni joints are nice and smooth and the splines are in great condition.
Only available from BMW complete.
