Mechanical Speedo with Front End Swap? 08 Jun 2019 12:48 #805366

nixon Topic Author Offline User Posts: 22 Thank you received: 0	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!

If so, does the drive on the wheel look like it will accept the KZ drive? 1982 KZ1000 LTD parts donor 1981 KZ1000 LTD awaiting resurrection 2000 ZRX1100 not ridden enough

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.

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.
