Q: why get size 2? clarenceyuen 4 years agoAnswer
any reason to get size 2? do u need size 2 for higher HP applications?
A: Sizing of the bearings is determined by the clearances that you desire. So that depends on the size of the crank after you measure it, along with what oil you use, and type of use the motor will be put to.
