SKY <> So I understand my Tokico pads won’t fit the Nissin’s, but I’m still unclear as to which pads to purchase. If I hypothetically purchased 2012 ZX-14 calipers, I would have to purchase ‘12 ZX-14 pads & they would fit my ‘04 10R? Same question applies to any of the Concours or the 6; just purchase pads for the matching model & I’m good?
OK, I'll try to explain it a little bit better.
The calipers are the same for the ZX-14, the ZX-6R, and the Concours for those years. The pads are the difference there. They are physically all the same size and will fit, it's the friction compound that is different. The Concours is a heavier touring bike, so the pads will have less friction and last longer. The ZX-6R is a lightweight, high performance machine so the pads will be higher friction point with more wear. The ZX-14 is a heavy sport model, so the pads will be decent friction with improved wear to account for more force needed.
You don't match the pads to the model of the bike like you're describing. If you get ZX-6R calipers, throw some ZX-14 pads in it. If you get ZX-14 calipers, throw some Concours pads or ZX-6 pads in it. You could get ZX-14 calipers and put the ZX-6R pads in them or some Vesrah RJL pads for a ZX-14. The pads will determine the way they feel and respond and the compound of them changes the part numbers. Since the ZX-10R is in between all of those things in terms of weight, you'll just have to pick one and try them. They all fit and will all work across the board. Doesn't matter what you choose, since they will all be way better than what you have now.
You buy the pads to match the type of caliper, not worry about whether they will fit a ZX-10R. We've already determined the calipers will bolt up to the ZX-10R, so the pads fitting are not a concern. Get the pads to patch the caliper, and then match the caliper to the bike. I had ZX-14 Nissins with OEM ZX-14 pads...top notch!
