What do you think would give better braking power? I’ve got the stock dual disc set up on an FXDX so I’m debating which route to go to improve stopping performance.

On my last FXDX, I went with Tokico calipers on Speed Merchant brackets. It never felt like I got the pad alignment right. The lever feel was improved and the braking was better, but not what I felt it should be. Also. the fact that one has to purchase used, 15 year old calipers on eBay makes me a little weary. I know tons of people do it, but it is kind of a roll of the dice. Who knows the condition of the take-offs from a salvaged bike....there’s no source for new Tokico calipers for 2005-2008 GSXR......or is there?

On the other hand, I hear good things about the Ness single big rotor kit, so I figure a dual disc set-up would be fabulous. I’m also sitting on a pair of bagger Brembo calipers to sweeten the deal.

Whats everyone’s 2 cents?!

 

I may be mistaken but I think that AN has stopped making the big rotor kit for your bike.

 

It’s still out there. You have to buy left rotor and a right separately.

 

I would not worry about the caliper since there are repair kits available which can include new pistons if needed. If the caliper body is good ie: piston bore spotless and all threaded holes are good it can be brought back to good as new condition.

 

Soooo any thoughts on what would stop better?

 

Rebuild kits are pleantiful so I wouldn't worry much about used. You also don't need to limit yourself to just the 05-08 Tokicos. Most modern Japanese sport bikes use 108mm calipers and should bolt up with some shimming. I have a set of Nissin's off a '12 ZX6R that I hope to get mounted this winter when I do the suspension.

 

Spend your money for us and let us know which is better 🙃

i really don’t know how much stopping power you want. My radial tokicos and Galfer rotors bite!

 

Even that's not very important. As long as the grooves for the seals are good, the sealing surface is the piston, not the caliper bore. Pitting in the bores themselves is harmless. (In other words, most used calipers will work. Worst case is you'll have to replace the pistons.)

 

Piston bores is a broad term and of course includes any seal grooves. generally if the bores are bad the sealing grooves will be affected also.

You can also use Honda CBRR calipers with simple mods, just depends on the brackets you use.

 

Braking is not just about the squeeze it is about being able to max without locking up... Too many other factors to say which will get it closer to that point while still turning rubber.
