I'm not sure why, but I have an idiosyncracy about knowing the temperature and fitted a digital temperature gauge (thermometer) to my previous bike. I bought it cheaply from a local automotive parts shop. It was designed for a car dashboard, so I had to take it apart and silicone the housing seam etc. to make it waterproof. This weekend I made a little aluminium bracket and mounted it on my R3. It actually came out nicer than I expected. Photos uploaded below..
