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 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.

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.
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.
Its the width between inner plates that worries me. IMO its not good practice, I like my bike to be aircraft perfect in certain areas. 525's are a much beefier chain and you may have clearance issues in some places.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.

I bought this chain riveting tool and it worked well.Picked up a 120 link DID chain from the dealer on a whim. Got the rivet one - not the master link, but making the rivets mushroom isn't that easy using cheap chinese tools. Any tips or tricks to get them to mushroom enough?
All I did was take off the old chain, lay them side by side, and then took off two links from the DID chain.
What was weird was that when I put the new, unstretched, chain on the bike it was super loose. A turn and a quarter (~1.25 turns) of the swingarm tensioner bolts fixed it perfectly.
Now we can argue how taught our chains should be. I went for 5-6mm as I don't want to cause issues with seals, but I'll keep an eye on it all and tension a little bit if I need to.
