I've got a set of take offs for those exact wheel size from my Honda 450. The front is a 120/70/17 and the rear is a 155/60/17. The nice part about the read being a 155 is that you don't have to worry about chain rub on the rear tire. You can have both for $50 plus shipping. Shipping can be a little spendy though ($30-50 depending on how fast you want them, and the distance to ship) I'm near Chicago. Let me know.
