Actually if you ride only on the street, the 17 in. wheels will allow you to put much better street tires on your bike and you won't have to switch back to the original wheels/tires unless you decide to ride off-road. And your bike will look MUCH better :teeth ;)
:infrandom
But what does dropping the size of the front wheel from 21" to 17" do to the steering geometry? Intuition says it would take a bike that is already a little twitchy and make it that much more unstable. Does that not actually happen?

Also, what's the purpose of swapping the rear wheel, which is already a 17" rim? It was my understanding that you couldn't increase the width of the rim much without having the tire scrape on the swingarm. So what do you gain by replacing it?

Bike already has street tires on it, by the way. I wonder if it would even make sense for me to use super-sticky tires, since I am a very unagreesive rider. And I can't afford to be replacing my tires every couple thousand miles.

with 17's on your bike, it will handle much better, then with the
21" on the street. your rear wheel should be 18".

The rear wheel on my DR really is 17", not 18". It's supposed to wear a 120/70 17 tire, but the tire I have now is 130/80.
