Hey guys pretty much positive I wanna go to a 15T front sprocket to give me that wheelie making torque on the low end :rockon: Just wanted to double check if I need to/should replace my chain at the same time? Also, for those who have the -1 front sprocket on their bikes already, how much speed do you lose off the top end, if any? Thanks guys, 'preciate the responses!
