Need help

Hi I've got a neos 100cc with bar con on what speedometer can I use as not sure where to get them from its my first time doing a convert

 

Pedparts! Massive range

 

I've looked on there but all digital will they still work or do I need to do anything down on wheel where speedo connection is

 

They come as a complete kit! Everything you need... don’t they?

 

Yup, magnet on the fork leg and front disc for speedo pick-up, then you have to calibrate the settings for the tyre size to get more or less close to true speed. Then use a gps to verify.
