My guess is it is a method for circulating the brake fluid to avoid overheating the fluid. I am more interested in the Barracuda air box cover

I'm surprised to see the factory can - figured they'd drop that chunk off there..

Nice gallery! On the front 1125-1190 picture was the 1190 fork larger and with a bit more rake or was that the camera angle?

It's somewhat common for endurance applications. Even back in the 60's the SCCA cars used it to keep the brake fluid cool. Actually works pretty well.

Same question - do you crack the bleed screw open just a hair and route that back to the reservoir?

I like the vinyl wrap that looks like it was made from the Buell poster artwork

Dannybuell,
In regards to the forks, I have no idea from the external view if the internals are different. However, those forks are BPF (big piston forks), new technology from Showa. They’re the same type of forks introduced a year ago on the ZX6R. I believe that was the first bikes to get them; anyone, feel free to correct me.

That rotor is the 5MM finned rotor.

Surprising to me is they are still using the original OEM mounting hardware.

EBR sells a new hardware setup with a diaphragm spring instead of the compression spring in the wheel. Between the wheel and rotor is a new spacer and a copper washer.

The design is to float the rotor a little less, and far more efficiently dissipate brake heat into the wheel itself.

My experience with it so far is it's great... Between the finned rotor and new mounting system I don't built up nearly the same levels of heat in the rotors, and I far less regret NOT getting the left side remote adjuster for the brake lever.

Oh, and it's time for them to replace their drive bushings:



See the piling of the stainless steel making a burnished edge on the rotor right under the fastener? That's drive bushing wear cutting into the rotor itself.

I ruined more than one rotor not keeping an eye on that...

So how exactly does the recirculation work?

Not sure how the recirculation works but I'm going to take a guess - there are probably two pistons in the master cylinder and one closes off it's bleed hole a tad later than the other. So for every brake activation, a small amount of "used" fluid is returned to res from one line, and is replaced with "fresh" fluid from the other line.
