I’ve done a few speedo adapters here. One puts the speedo to the handlebars. The one included in this file, I haven’t tested as of yet. There is also one which moves the speedo to the side, allowing room for a GPS or other bits next to it. I’ve used this, but it needs to be slimmed down. It weighs so much that it just causes things to shake like crazy. If you run a brace with it, it may be fine. While reviewing the files, I dont’ think I finished integrating the speedo with the GPS unit. I’ll have to dig around some more, I can’t remember. An keen modeler could tackle such things.
