Bigger front sprocket and smaller rear equals, downshifting on hills more often, especially fifth gear to fourth. Maybe if you live in a flatbush area, not so much? There is a point, that at the higher ratios, you will seem to lose both torque and H. power. I put a wide 16" wheel on the back of my '05 and at idle in first, she rolled at about 12-14 MPH and I practically longer needed fifth gear, a 16/43 setup, got things back to where I liked the gearing again and she rips now. You have to have, more power than stock, to really appreciate the higher ratios, IMHO.
