There's no doubt that with a little patience, changing a tire is quite doable for the home mechanic. As usual, good tools make all the difference and a couple of decent tire irons go a long way to making it easy (Examples shown are available through
www.fasteddysports.com ).

To protect the chrome, use a 6" chunk of garden hose split down one side and place it on the rim where the tire iron hits. Then, just go at it like you've done with your dirt bikes, making sure to line up the red dot on the tire with the valve stem.
I take my wheels in for balancing (usually required after every tire change) but some members here balance their own.
