[quote="mattf"]I have both sets of stock wheels, the wheel swap itself is no biggie but the brake rotors are different so I also swap the entire front brake assembly and fork guards (unbolt the master cylinder and caliper leaving the brake line attached, then bolt back on the other complete brake set up) without rushing I spend roughly a half hour swapping everything.

This is the exact setup I have for my R. No mess with caliper swapping and it gives you the stock brake setup for either bike (X or R). If you can get ahold of the parts that you need for a good price, this is definitely an easy way to go.
