Looking at them it seems pretty thin to get 3.5ish mm out of it. I’ll probably have to wait until riding season is over and really tear it down.

Yeah, I noticed that later. May be too tight yes.
Here’s an exhibit why you should not get bored and order parts... cheap light rotors from rc8 obviously will not work. Not sure how I missed that the number of bolts is different. Got caught up in that the rims and bearings are identical.

Two cents: part of the justification for the single is the lightweight aspect of this bike. Dual disks would make sense if it were 100lbs heavier.

I was initially put off by the single, and actually thought it was underpowered - I like single/dual finger pull. But I have to use the 3-4 fingers on this bike. Nothing big, just not my preference. Still, slightly underpowered and you have to put some real intent into braking.

So I swapped out the OEM pads for HH, and am happy I did. I think it's about halfway to where I would like it to be. So, a good perf uptick.

Instead of a dual, consider using a larger rotor and making the modifications for it. I think this would be much easier to do if a rotor is available. A relatively simple bracket could be created to move the brake to the desired position, and a larger-diameter rotor would add more swept area per revolution, as well as a larger moment arm to the braking action. Not sure about available diameters or having ABS compatible rotor available, but a thought . . .

Good luck.

Good point, I am not sure how much there is to gain by going larger without going to a perimeter rotor like buell. The main reason I want to do it is for the two finger braking and the looks, I fell in love with the concept bike and when they released it with the single disk it just drove me nuts.

All this talk about fingers, with some "upgraded" brake fluid and regular Road sinter or HH pads there should be more than enough "action" to put the ABS to work with a single "middle" finger pull... easily.

I am still convinced its only for cool factor until you can go over 150 mph where it actually counts to have dual discs.

And I like that someone is willing to "waste their time" adding to the cool factor of their bike

I agree that it is not necessary, however I really want to be able to put white mag wheels on it and I dislike the single disc look. Also want to lace a 790 adventure hub to the stock rim so I can use spokes as well if I choose.

I also ordered an rc8 front rim, I think the savings between that and the brake disks will offset making a custom abs ring Mount.

It already is 320mm, the max that will fit a front wheel is 330mm, not much gain, and getting the wheel out can be quite the challenge.

Incase anyone is thinking about it, I was looking at throwing one of the m50 brembos I got onto the stock front end just to see how much it improved but the angle on the brake line fitting won’t work so if you want to use those on the stock set up you’ll have to get a custom brake line. Not worth it to me since I have to get custom lines for the dual set up.. Not a bad upgrade for the stock front brake if your sticking with the single one, I got the two m50s off a Ducati 848 evo for 350 US.

Not related to the disks but I remember a post (possibly on the other forum) by someone who had done a really great job of getting the look of the concept bike. Had cut their exhaust down and installed the clamp on filter.

That is a good idea with the exhaust, maybe I’ll have to get a stock take off and try to cut and weld it..
