Sku # Question For Crankcase?

[del518]

I have 2 white Crankcase with Jade Iridium. I am going to send one to my buddy in Indy for letting me stay with him last year and this year for the MotoGP race. What I noticed on one of the frames (before I Mail it out) is the additional '125' in the frame. Any idea what that means?

I believe that's the earstem length.

I believe that's the earstem length.

Any idea why it would be on one frame and not the other? I have 4 other color ways and this identifier is on none if them?

I have the 125 on my matte black/violet iridium too..if you look closely at the picture, I think the numbers were printed on a different place than the other..
