no no no...
I just put new tires on my bike for a total of $39 or so including the balance. I already had the tires of the bike, and just took the rims in. Which in "most" cases is cheaper then just taking the bike in.
I would look around. If you went to the H-D shop, they always charge you full price for pretty much anything. Look at other dealers. Should be able to find something cheaper then that.
