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 signs of wear as to be expected for its age and is priced to reflect the wear. Still a lot of ks left in it if your shaft is still OK. 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 used in good condition.
