I don't know about the VMAX Mirrors but I wouldn't buy the Kuryakyan mirrors again. They do make special adapters for the America/Speedmaster for $19 for two little peices of alumnium tubing. And they do vibrate becuase they really don't fit that well. Gives you the experience of riding a Harley.
My understanding, and I may be wrong(as my wife often reminds me) the VMax mirrors fit onto the end of the stock Triumph mirror stalks. The Triumph mirror stalks have little perforated spacers shaped to fit the cavity in the handle bars to prevent vibration better. My stocks ones never vibrated but I wanted square mirrors.
