I'm looking for caliper adapters for the RC to fit Brembo 40mm bolt pattern axial GP-calipers. Yoyodyne has one on the website from Agras, but they are telling me it is discontinued.
Anyone wanting to sell me a pair? Are there any other manufacturers?
Activeand also Posh make some nice billeted ones and not too dear
also maybe that maker in China might have some on ebay(makes those cheap caliper mounts)
This is a delicate subject in these waters because for the entire life of the bike most have scoffed at the idea of spending more time, effort and money on upgraded calipers has been largely frowned upon in the RC51 community because of the outstanding reviews/opinions out there on the above par performance of the OEM calipers with the std upgrades of braided lines, new rotors and HRC/OEM spec pads.
This discontinued set is the source of the calipers shown in this picture but mounted up with the new style snowflake HP rotors that replaced the OEM sized SBK non-narrow band rotors:
I don't recall what the caliper mounting bolt spacing was on this kit, but if you get yourself a set of new style ohlins R&T forks you can borrow my brackets and have them replicated for your 40mm race calipers.

Thanks for the offer! I was quite happy with the brakes I had but I needed a set of rotors since mine got warped after extensive track use. I could always fabricate some brackets myself, but from experience it is often more work than you'd expect from such a simple part.
You can spend alot of time and effort and in the end have useless polycarbonate (plastic brackets) but a good prototype...oh ya I gave these to stun-gun !!!
If you have calipers with the same bolt locations as Jason's (stunna), and can convince him to take some measurements, I can draw some custom brackets for you. We can have wingnutt make some prototypes before you spend any real money at a machine shop.
That is also assuming you have the same size rotors (i.e. the calipers need to be the same distance away from the axle). I assume you have stock front forks too?
I know that brembo has pdf's out there with the dimensions on most of their current stuff. So you might be able to find the same thing for yours. Do you know what the model number is?

I'm happy to help out, but my HRC wheels have different spacing than the OEM and my rotors are made specifically for these wheels.
Then there were spacers made up to correctly center these wheels/rotors between the Ohlins fork legs.
I am wondering if you could use an OEM fork radial mount caliper/bracket to work with the narrow band rotors you got? Not to say that they are better than brembo race axial mount, as I am a firm believer that they're not, but it may be an easier route than having new brackets made to accomodate your brembo race calipers...

I am confused, are you using regular 320mm calipers or narrow band? The rotor PDF doesn't give much info other than the outer diameter.

What I would need from you would be the distance from the axle centerline to the center of each of the mount bolts. But I might not need it at all with the drawing that he posted. With that I can figure out side to side placement.

Sorry for the confusion. They are narrow band calipers and so are the rotors.
LOL, Thanks! Hopefully yours came with pads cause mine were shot and now Im stuck investing over $200 on just 4 front pads alone not to mention the 2 I need for the brembo race rear.
Thats true, in the same sense they were also one of the first SBK's to run the radial mount's as the factory HRC SP1/2's saw both axial and radial braking setups througout the different seasons.
It would be interesting to get a comparitive opinion from some of the racers who were lucky enought to get to experience both and see which each prefered.
Its odd that Fred is still advertising these Agras 40mm race caliper adaptors for the SP1 if they no longer sell them VTR1000 SP1 Caliper Adapter . Has anyone tried contacting Agras and finding out if they have any remaining or if they would make more or sell the CAD file for you to have it made one off? It would also be important to know (if you can find one) if the Agras bracket would fit the 40mm caliper to an OEM or an HRC side/side spacing and if it would position it to fit the OEM or narrow band rotors.
I don't think the brembo caliper adaptor for OEM forks I had pictured above was made by Agras. Don't recall the brand, but now I'm sure they were a 65mm mount spacing vs the 40 you need. Interesting that they wouldn't mount in the OEM position even though the spacing is the same as OEM.

The RC is one of the last superbikes with axial mounted calipers and I like them better than the radials.
Caliper adapters, where to find?
