R6 TRS pins in R3?

Can anyone check if R6 pins will fit (snuggly) in the R3 axle?

 

Or if you have R3 pins tell me the OD of the portions that slide into the axle.

 

R3 pins slide over the axle, not in. Going to be very different.

 

Having both, completely different pin design.

R3, one pin is a hex that covers the axle nut, the other side then has a nipple that goes into the axle and they're further into the arm than the R6 pins. You can't remove them from the U arm while the attached to the bike.

 

Damn, I guess they used a generic picture on the website then. Sounds more like the Ninja 300 setup.
