I have a 2018 NC750X with stock 140/40-17 rear tire and stock 17/43 front and rear sprockets. Im going to need a back tire soon and want to go to a 160/60-17 rear.
I used the gearing commander calculator and found if I use a 16t countershaft sprocket and a 160/60 rear tire the difference at 70mph is 1.5mph from stock. The difference with the stock rear 140/40 and a 16t at 70mph is 4mph.
I can live with a 1.5mph error on my speedometer. I think the gearing change will compensate well for the tire change. Has anyone else done this?
