I have a set of stock take off mirrors for sale. Don't have a clue what they are worth but make me an offer and I will prolly take it.
Also have a set of Emgo Billit Sport Mirrors. I bought them and never used them since I got the CRG's about the same time. I did mount them up and they looked pretty good on the ole 919 but just not the look I'm going for.
$50 Shipped to your door and it comes with the Yamaha adaptor.
