Has anyone thought of using the speedo sensor from a 1996 CBR900 on an nc29 front sprocket cover to provide the digital input for a digital dash? That would have to be tidier than sticking magnets to your brake discs, wouldn't it?
Just a pipedream about eventually fitting a digital dash, nothing too exciting or immediate :)
Looks like it might fit? If so then you could use a converted nc29 front sprocket cover on nc23,27,29,31,36, and whatever else uses the same engine.
