Hiya and welcome to this wonderful site!!! I am sure you will get some suggestions soon, but which model have you bought, XT660X or R or Tenere??? I have the original Yamaha/Acerbis hand guards and also the original Yamaha aluminium bash plate on my X. I have just bought some Givi engine bars but I have not fitted them yet as I wish to mount some extra lights too. Have fun with your new bike!!!
