I think he is actually looking for the K1 round 4 speed speedometer. Unfortunately they are usually harder to find in good shape and expensive when you do. If you're just wanting a speedometer for a "rider" bike to make it complete, you can find a more common 3 speed unit and then install a 4 speed overlay decal in it. That is if your handy and feel comfortable opening up the housing and doing the work. If you want to find a correct 4 speed unit and avoid the work for yourself, searching for a SL70 speedometer may yield more results online too. I believe the 72 CT70H and certain year SL70'S shared a speedo unit.Would this work? will have to modify the wiring a little, maybe some of the more knowledgeable members will chime in.
