Hi to you all. I have a simple question, and, although it may seem obvious I want to make sure I don't get it wrong. "What is the size of the standard headlamp on the R3"? I have measured them and they are 5 3/4". I have searched google but these days there is so much crap to plough through its a nightmare to get the right answer. I just cant afford to get it wrong and buy the wrong size. So can someone who knows let me know if 5 3/4" is the right size. I am after both headlamps as the glass is shot on both mine. the metal housing/body is good as are the chrome clamps, its the glass and inner that I need. Thanks for your help.
