I like Ronayers.com the best. You will find that they are all about the same shipped to your door.
I did just get one for the X and one for wifes v star at hdl and got the 10% cupon code deal and got them for $224 to the door, and these were Metz 880 for the fronts and the fronts are alway more than the rear, go figure, and I think the rears have more tread on them.
I checked around online and the price from a local stealership was very close. Shipped, I could have the tire in about three days. Dealer said they would have in the next day and would do the mount for free if wheel was off the bike. Paid the $10 more the dealer wanted to have it the next day and mounted.
