Used top and bottom fork brace to suit K75S and K75RT post 08/1991
This take the SHOWA 41mm forks not like the earlier bikes that took 41.4mm forks.
This will fit into an earlier K bike if you are looking and changing the front suspension to 41mm forks. I had them in a earlier K75 with SHOWA forks I was looking at modifying.
You may want to change the steering head bearings. Up to you.
