New there was only about $1,000 diff, so you can probably find used ones and their parts for about the same price. To make it "faster", you'll probably find more aftermarket stuff for the 450R, and since it's about 100 lbs lighter, you will likely find more results with similar changes.
But if she likes the ride and fit of the 700 better, that counts for something and going slightly faster probably won't change that.
And unless you are planning to race, why exactly do you need either to be faster?
