Mechanical Speedo with Front End Swap?

08 Jun 2019 12:48

I've got a 1981 KZ750H LTD with a front end swap from a CBR600 F4 and I love the original mechanical speedo. I'm wondering if anyone has ideas on how it would be possible to keep the speedo with the new front end swap, or if I would have to switch over to a digital speedo?

Thanks!

Here is a picture of the swap, just has a bunch of tape on it to protect it during the build.

Does the Honda speedo take its reading from the front wheel like KZs with electronic speedo? If so, does the drive on the wheel look like it will accept the KZ drive?

Thanks for the idea, but it's unfortunately not run mechanically off the front wheel.

I swapped from a 19 inch CSR wheel to a 17 inch ZXR wheel and just connected the ZXR mechanical drive up to the CSR clocks. I measured the length I needed and got a cable from Z1 enterprises (no idea what bike its from). Works fine. No idea how accurate it is but Im sure its close enough.

Sounds like an easy solution. I was hoping to do the same, but it's a speed sensor on the CBR, not a mechanical drive.

You're probably going to have to get a digital speedometer then add a speed sensor to the front wheel or whatever sensor they use. From the diagram, the Honda seems to have the speedo sensor located on the crankcase. Trying to adapt a KZ speedo drive to the Honda front wheel is probably near impossible.

That was my thought as well unfortunately. Thanks for the input. I'll search for a digital speedo with the vintage appeal.
