Good usable condition Z16 driveshaft for all pre '86 K75/100 2 valve bikes. From a 1985 K100 with low miles on the speedo. The splines are still very good and have a lot of usable life left in them. The U-joint is a little notchy. Use it for a while and then have it rebuilt. Will not fit later 20 spline models. BMW gets $387 new for these, save big here!
