Just change out the front there only about 20$ and if you go down in size in the front forinstance... Stock=15 Top End=16 Bottom End=14 just as an example. the rear is opposite, the smaller you go the more Top End you gain the bigger you go the more bottom end.
I found this @ atvnews forum:
"i just checked the gearing on my 700's.. 14-38 20" rear tire."This should have read: Stock=14 Top End=15 Bottom End=13
Just an FYI
