So as my bike is sort of an evolving test bed for R&D I decided to try the EK 3D SB chain. Traditionally I always use the DID ERV3 520. So like an ....., I was not thinking of the possible idiosyncratic mindset that exists between manufacturers and installed the 3D. I now have a few scratch marks on the swing arm. No big deal. Im not a cosmetic guy. The issue is that had i not failed to measure the width of the pins between the EK and the DID, this would not have happened. Point. The EK 3D SB 520 chain is wider by 4mm than the DID ERV3 520. If your one of the guys who has an issue with the stock 530 rubbing on the swing arm and switched to a 520 setup and fixed it, you may have a clearance issue with the RK 3D 520. Im guessing to get their claimed strength numbers that EK beefed up the plates a bit. Unfortunately, the EK 520 is almost the size and weight of the 530. Well i gave it a shot. Nice looking chain. Im going back to the DID.
For all the 520 Chain converts out there just and FYI

So if I don't want cosmetic damage to the swing arm, stay with DID chain, right,?

Good information, thanks.
Thats a bad one especially since there were numerous stages where that should have been spotted prior to delivery. I have actually measured 3 swing arms including the one on my bike. Measuring from the machined surface of the outside of the axle slot to the point of potential chain intervention, all three swing arms were different. The installation of the right and left axle fixes the swing arm in place. There are no adjustable parameters there so if there is a variation in the machine prep of the arm you can have an issue for sure. The good thing is that the area that gets abused is part of the solid cast piece and not located on a hollow section. Even a deep gouge should have no bearing on structural integrity.

The "backwards" countershaft sprocket has been an ongoing thing since 2012. Can't believe it's still happening.
Is there no guidelines on what constitutes a 520 chain? If it is or almost the same width and weight of a 525 or 530 chain, why can it be called 520? Is it just based on the width of the sprocket teeth?
Sounds very misleading doesn't it?

Yes width of the sprocket. In the case of the DID vs RK the space between the inner plates that contact the sprocket is the same. The thickness of the inner and outer plates on the 3D chain are thicker giving the 3D chain a thicker outer profile by about 4mm. It's close if not the same as the stock 525 chain in at the pins. It's definitely the heaviest 520 out there.
What is this set up? Looks good.

Stock chain was rubbing on mine. Decided on an AEM setup with 3D chain. No issues.
