My experience with the fronts is that the 60 is shorter and steepens the front end, speeding up turn in with less stability...Going to the 120/70 front raised the front and provided a slower turn but more stability.

My SV race bike came with the 60 series front and when I swapped to a 70 I raised the rear by almost a half inch to get it in the sweet spot. My ZX636 came with a 120/65 front and likewise when I switched to the 70 I had to raise the forks a little to get it back turning in sweetly...
