Hi new here. I love my C109RT but when I ride at night I get a bad glare on the wind screen from the lights inside the speedometer, this is vary distracting. I would like to find a speedometer visor to block the light but I cannot find one for my bike. Are the speedometers the same on all of the C's? I found a nice one for the C50 but I don't know if it will fit. If someone could help I would be vary appreciative I have searched every where. The speedometer is 5 1/4 in diameter if you are able to find a universal one. Thank you for helping a new guy. Keep the rubber side down.
