Good used 16 spline rear drive to suit K100;K100RT up to 2/86. Ratio is 32/11. Rear drive does not come with the speedo sensor. You will need to replace with the one from your old one. Spline is showing a little sign of wear as to be expected for its age but is one of the better ones I've had in. Rotation is smooth. Please check the photos before purchasing.
If you are not way to far away' you could always come and check it out by appointment. These are heavy and postage will be a lot.
These are getting harder to come across now.
This came off an ex police bike that sat for many years.
