I need someone to help me determine what color or size rod bearings I need to order. I’m installing aftermarket rods big end bore is 39.5mm on all rods and crankshaft letters are BAAB 2011 cbr1000rr any and all help greatly appreciated o

 

This from the service manual - you need a more exact measurement of your rod size - unless it literally is 39.500mm exactly?

 

I havnt measured myself but that is what the box says. 39.5mm


 

You'll need to measure them then - the bearing caps are a few hundredths of a mm different.

 

Those tiny differences can be tricky. Hope you figure it out soon.
