One thing you need to know about the Motogadget instruments is the build quality can be sketchy. I've got them on several bikes and they can be a real pain to keep working.
They are on a XS650 a SR500, a Norton Commando in a Featherbed. I've got another sitting on my bench that I purchased for a BMW project. They HATE vibration. The last two would fog up if they happened to sit in the sun for more than 30 seconds-no, they've never been so much as dribbled with water.
