The difference between a DID 520 and a DID 525 chain hopefully isn't very important as the chain I put on was a 525. Maybe sprocket wear will change? I only had about 900 miles on the sprocket when I completed this swap so basically brand new. I definitely liked that the DID 525 came with a rivet master link as opposed to a clip master link that comes with the 520.

I know the manual states that stock equipment is a "5/8 x 1/4 (520) X-ring" type chain, but it would seem that the 525 works just fine, at least in the short term.

Time will tell!

I don't know if using a 525 in lieu of a 520 is correct or not. From all the motos I've owned, I've always changed out the chain & sprocks as a kit. It's prolly ok that you changed out the chain while all is basically new. I would look into my first sentence though, that would irk me.

Technically according to the manual, 525 is not correct and 520 is. I'm not sure there are any hard negatives to running a slightly wider chain. The lateral space on the sprocket is obvious, but what would the long term effects be? I'm just annoyed at my dealer for recommending the 525 over the 520...

I have a chain adjustment tool and a breaker/riveter tool on order to help dial in the tension and replace the chain if I absolutely need to.

Did some digging. No negatives to running a 525 chain on a 520 sprocket. The main difference that needs to be thought of when choosing sprockets is the width between inner plates. 525 chains last longer but are 100% compatible with 520 size sprockets.

Width between inner plates
520: 1/4"
525: 5/16"
530: 3/8"

Anyone know?

Thanks!
The original has 118 links. We had to take the original down to test the bigger sprocket (56 teeth) that we made for the 790 Duke.
In case you are thinking also to change the sprocket, for 56 teeth, you need 122 links.
