You need a billet master cylinder now to complete the MotoGP spec brake setup.

Wow, I never seen a black color Cerakote before, that is very beautiful, the way it was spreading on the surface, more like anodized instead of paint !Cerakote done
So I got a couple parts done in satin black. The finish looks great and should last a long time.
Im going to test fit the V4SL caliper bracket soon to confirm fitment.
Yeah it’s really hard to tell the difference between Cerakote and Anodizing.Wow, I never seen a black color Cerakote before, that is very beautiful, the way it was spreading on the surface, more like anodized instead of paint !

Agreed. I had the brackets the rear sets bolt to coated and it makes such a difference.
V4SL Caliper bracket
Confirmed this fits and clears with my Fren Tubo brakelines. Not sure if the stock line has enough slack to work. Pretty straight forward install the only pain was the circlip. It tried to end my life lol. I was wearing safety glasses and had everything covered so no one was hurt.
Lets just take a moment to look at the gloss.

thats where one of the benefits of Staubli disconnect is good for, switching out applications...So nice!
Would be awesome if you could do a track day on the stock calipers, and then another at the same track on the new calipers within a few weeks of one another, to get a back to back impression.

Agreed! Saw that this weekend at COTA with Brad.

You still have to remove the calipers though. For a true quick change setup, you have to run more widely spaced forks (so the calipers are far enough apart to allow the tire to be pulled between them), which requires a wheel with a wider hub.
Yeah for sure. The pain for me is the calipers always want to bang into the wheel when putting it back on.

Aaah yes - for that the qd lines are awesome!
Edit - I think I’ve seen folks use zip ties or wire hangers to hold the calipers.

before, I used one of boot's box to rest on top, so.......many ways to skin a cat...they said...
Ive done that along with the bungee cords. Its great until it swings into the wheel lmao. Now I wrap both calipers in MF towels until the wheel is in.

I could be wrong, but isn't that why the fancy forks for endurance racing can pivot the calipers out even while the bike is on a stand? Looks like instead of the hub being wider, they rotate them out of the way for wheel removal and just pop them back into place once it's back on.

I’m no subject matter expert - I am only repeating what I was told from a reliable source.
I discussed this issue with Brad Miller (@MotionSBK), because my 2015 R has the Fast Frank quick change axle and I was hoping that would allow for wheel removal without caliper removal (“endurance style” like you said). I was planning to get the FF setup for the v4 as well, but Brad explained to me that the quick change setups seen in endurance racing require fork legs that are more widely spaced, and wheels with wider hubs. I didn’t verify that info independently though.
Seems to me that if you simply rotate the fork leg, one end of the caliper will rotate outward while the other rotates inward and you still won’t have more clearance to pull the wheel/tire through.

probably that's why FF hasn't made the kit yet....I’m no subject matter expert - I am only repeating what I was told from a reliable source.

Fast Frank quick release axle
I've been trying to get FF to make a Ti version of this kit which has failed lol. So here is the standard version of his quick release axle. This allows you quickly remove the front axle without having to mess with the fork pinch bolts on the clutch lever side. The pull cup also makes the job easier.
Weights and measures
I was worried that this axle would add a lot of weight but its not as bad as I thought. Like most I have fork sliders on for protection so when you take those in consideration here are the numbers.
200g
Stock Axle 378g
Ti Axle 218g
FF Axle 540g
So if you have a stock axle with rizoma sliders you are actually heavier than the FF QR kit.
Here are the totals which include the rizoma fork sliders, axle and axle nut.
Steel setup 596g
Ti setup 434g
Since I had the Ti setup this QR axle is going to add 107g which I'm ok with since it will add convenience and style.

I would consider after I get my carbon wheel next....hmm...Fast Frank quick release axle
