I hope you're right. You listed different diameters. Maybe if one of those bikes that the kit goes to matches the bikes using the same calipers as the Rocket it might be more likely to be the right size. Here's the chart of matching calipers...
If you get a rebuild kit and it fits I, for one, would sure like to know.
If you put in your bike on the Brembo website and go to calipers, there's a link to "compatible vehicles" and it lists Aprilia, Ducati, and Triumph. Should be a kit for one of these out there. Put in your year in case there is a difference (doubt it) for newer bikes. Here's what I see....
Measure pucks and order seals, 30mm probably but seals for calipers as mentioned calipers are available.
