He Jens,
I would love to see you on a bike on the track in a race (-:, that would be funny. |

Me? For what? I let bikes go fast, you talk about it. |

OP are you using the upgraded mounting hardware for the finned disc? OR are you using the factory bolts with springs....
I have about 1800 miles on my rotor setup with EBC pads and the new hardware kit from Erik Buell Racing.. NO shudder...
Just a thought.. |

>>>>send 1 disc to the pegasusraceteam,Harald can tell you then how good it is.
That really makes some sense if you are wanting to add any credibility.
I do not know if it's better or not.
But . . . after seeing 3 engineers spend a couple years, hundreds of thousands of dollars in analysis and testing . . .seeing Danny Eslick win a Championship the first year Buell raced . . well it makes it a great leap of faith to simply accept the "it holds better then the 5mm and the 6 mm" claim of an unnamed riders and an unspecified testing protocol.
I guarantee you that, like Jens, ANYONE would be faster than I.
My fast days are years behind me . . . but I do know good science and quality.
I'd enjoy hearing Harald's comments. |

Easy,
I'm sure the rotor is nice, but the primary problem I'm aware of is actually the rotor mounting hardware, not the rotors themselves. This is because the allowable float engineered into the Erik Buell Racing design is below the typical real world tolerances of the OEM front wheel. So, sometimes you get one that works perfectly (I have two that do), and others that don't work so well at all (three others for me, including both of my Mg race wheels).
Are you suggesting your rotor design will deflect less under heat and load than the 5mm model? Or, that it simply won't get as hot outright (dissipates heat better)? These are significant claims, and I'd be very curious to hear more. |

Jdugger,
The real problem we found for the disc heat cause, whas heat build up in the disc. Together with the Galfer designers we did a little study on the 6 and 8 piston calipers. after the study they are now developing a new caliper kit that give the brake pads more clearance so less friction and less heat build up.
The concept is you need a disc, pads, and new kit for the caliper to fight the problem. Galfer is the only company in the world that owns the patent on inside and outside wave pattern and yes that is including with the design 1 of the aspects to have less heat build up.
Here is a nice story http://www.galferusa.com/html/p_r_m.html
I can only say i do not quickly find a professional company like them. We are developing a complete brake disc kit for all Buell models with them to be able after 2019 to supply customers with the best parts for there bikes so not only the 1125 models. |

I love the guys at Galfer, they did some nice brake pads to work with a very unusual disk material for some test work for Buell, and did it very quickly and agreeably. However, based on all the testing done on the front rotor, and experience with attempting to develop a wave-like rotor for another Buell platform, and with some frank information shared by the engineers of another brake system company on their experience with wave-rotors and wave-like rotors, I would suggest that Galfer's wave rotor is perhaps not the best approach for the Buell front brake. However, giving the brake pads more clearance is very much a good thing, as is generally opening up the caliper for increased airflow. If you want to see what to do, just look at the latest AP Lockheed or Performance Friction automotive racing calipers -- of course, some of those sell for $6000 or so a caliper, and are wonders of CNC work. And certainly a brake system with such a caliper could offer further performance gains. |

I do think it's very cool ( brake pun) that so many knowledgeable folks in so many countries are looking at ways to further improve the Buell brakes.
The caliber of folks and the work they need to expend to advance the science speaks well about The Elves. |

I thought that was because Elves use Magic?

Speaking of the Buell braking system...
At Americade in Lake George there was an independent developer using the ZTL calipers and rotors on a "kit" he had developed to make your own super can am Spider type front end that bolts onto your existing cruser. This front end had the mechanism and suspension to lean into turns like a true 2 wheeler. With the flip of a switch it could switch between a fixed type suspension or a full lean suspension (hydrolics). Cost was in the 8k range for the kit and with some adjustments it replaces the existing front forks with 2 front wheels both with the Buell braking system.
He said he had made some improvements (rotor I would guess) and had attempted to contact Erik Buell but was not able to connect up.
It was one of the more interesting things I saw at Americade and if I were to bet he will be bought out for his patents. It looked like a pretty slick way to keep your bike but go to 3 wheels for added stability
The guy was from the Seattle area and seemed like an independent inventor more or less working alone and patenting as he went. I think he rode the bike home every night from the vendor area. |

Jdugger, thanks for the tip, those thinner copper washers did the trick.
Question: Do you end up with a .005 - 010" gap between the rotor and outer steel washer when using the thinner copper washer? With the thin washers there's no longer any preload on the spring washer - the rotor actually floats a little now like the OEM setup.

You don't want free play in the mounting. Did you use fresh belleville washers?
If so, and you still have play, step up to slightly thicker copper washers where you have free play. I think McMaster has them on .010, .015 and so on... |
