Well, yeah. What I'm saying though, is that I'll bet (a cold beverage of your choice) that they're all off the shelf parts and not specific to Suzuki, just to a 525 chain and assembly. I doubt Suzuki stamps out sprockets, but instead gets them from Spacely, and it's probably the same sprocket used on a bunch of stuff, not just Suzuki. JT isn't going to make them anymore, but somebody is.
