Should I keep the stock gearing?
I want to ask for some opinions. It is time for me to replace my chain and sprockets and I was wondering if I should keep the stock gearing or go down one in front. I know this will throw my speedo off if I do this, but my question is- is it worth it? My bike is an 01 CBR 929RR Erion. Also, a question on tire sizes. Currently I run a 180/55 rear, but a buddy is telling me a 190/55 would be better, as it will have more contact area. I ride mostly in the mountains. Any thoughts?
