Durability.
I used it when I converted from 525 to 520 on my Z900RS and it is about 600g lighter.
I was worried about the durability, but since I don't go to the Circuit, it has hardly worn off even after 20,000 km.
On the other hand, if it is for Touring with less load, I didn't think it was necessary to choose OEM or iron, only Merit.
