Upper steering head bearing set "Jockey's Boxenstop" for all Series 3 models built in 1965 or later without a chrome ring under the handlebars. 

Complete upper steering head kit, Made in Bavaria.

The steering head shell is designed to be used with an upper bearing ring featuring larger balls. This kit uses a steering head bearing with 4mm balls instead of the original 1/8" (3.17 mm) balls.  

Everything runs like a charm here, and all parts of the set fit together well.
