I'm sure it's the same axle & axle nut arrangement as is used on the CBR250R and CBR300R. On the right side is the axle nut, and on the left side is the end of the axle (which has a smaller hex on the end of the axle) which just slightly protrudes from the left fork leg, and is held in place by a pinch bolt on the bottom of the fork.I was wondering does the front axle bolt protrude thru the nut on both sides. On the right side I can see the axle bolt thru the nut. On the left side, I can only see threads. Thanks for any Info.
