What a cool set up but my S1 won't do 200mph so I have to wonder if I really need to carry all that extra stuff on my front axle. Even some of the Ducatis dropped the second rotor

Drop Court a note, he has lots of experience with a dual disk setup on tubers. From what I recall...it's a waste. Waste of weight, waste of complexity, and waste of braking power. The stocker has excellent brakes to begin with; as you noted above, if you're in the sub-200 mph range, why the need to add another?

It does add weight, but i thought court was talking about adding another 6pot caliper to the other side, as that was a complete waste.

I believe the Buell kit *was* another rotor, another fork leg, a splitter brakeline, and a mirror-image six pot caliper.

Ya'll are right about the weight and speed factor and espically the cost since I started looking at this idea, maybe I just need better pads!

rat, i am pretty sure the stock left side fork leg is ready to bolt on a new caliper, and although it may just be hearsay, the second rotor is not needed and mearly adds weight. One good rotor, a set of good pads and a braided stainless brake line (really important!) should be more than enough for the s1.

y'know, all I had to do was look out the window at my forks, duh. You're right, it's already got the mount points.

I had a couple different sets. One of the Buell kits still in the packaging--it went to Don Casto with all the extras when he bought my S-2.Good luck finding any of these. PM stopped making the mirror image caliper long ago,I checked. And none of the other bike manufacturers calipers do a direct bolt on. And it had a sweet set-up from ISR on the bike as well. Looked great, worked fantastic. If you have the means I would just grab a set of 6 pots from a Suzuki and make a couple of adapters to bolt to your fork legs.I saw a bike-XB- at Laguna the had swapped the Showa lowers for some from a Gix 750 and used the dual disc and wheel from that bike.

>>>From what I recall...it's a waste. Waste of weight, waste of complexity, and waste of braking power.

Beyond aesthetics it is a complete waste in that the bike takes longer to stop.

They are neat looking and somewhere here I have all the factory documentation for the few kits that were made.

I have toyed with putting the ZTL2 on the Uly . . but, again, mostly for looks.

The dual discs on a Buell do the same thing that carbon fiber does.

i would like to find a set for my drag bike

that way i could add weight and turn the calipers to the front to send some weight forward

one huge 6 piston caliper and a big rotor, or 2 four piston cailpers and a tad small rotors.....for a bike that tops out at 130 = complete waste of money, unless you are going for the wow factor. one GOOD brake rotor and GOOD pads go a long way

good point LimitedX1.

If our brakes are strong enough to flip us off, then adding more breaking power just makes it easier for that to happen... not stopping in a shorter distance.

somebody finally pointed out to me that the dual setups were small components. because i was looking into this as well (just like all of us buell riders did at one time or another because we see all the other bikes with them) well i dont believe ive ever seen another bike with a 6 piston front. a dual 6 piston front setup would be idiotic and would stop my pickup truck. the dual 4 piston and smaller rotor setup may have the same braking power as a single oversized 6 piston but at the added weigh of another caliper, rotor, line and fluid......the facts point the clear correct (buell) advantage out

and all the squids snicker at the single caliper......if they only knew what was actually ahppening inside their motor to make them go...

the real advantage is similar to running multi shocks on a 4x4, the heat dissipation is increased.

think about it, you get the same stopping power divided across the surface area of two discs, allowing them to cool before adding more heat.

is this needed on the street in everyday riding? probably not, but if you have ever cooked your rotor or boiled your fluid, this would be the answer.

i have ridden pretty damn hard at times, and have yet to boil the fluid or feel any major fade, so i guess i wouldn't NEED it, but i would still LIKE it.

using the weight argument is the same as the CF argument, the limited amount of weight added by an extra rotor and caliper would hardly be noticed by the average rider, just like adding CF would lower the weight slightly and wouldn't be noticed by the average rider. most riders would be better off losing 20 lbs themselves and taking a track day or two.

i know, it sounds like i am arguing both sides a bit, i am!

Great Bling, but like you said, I've never felt mine fade and I ride pretty hard too. A four finger "Holy S**t!" grab of the front lever almost launched me over the bars into the back of the minivan I was following. The wave rotor I installed just made it a one finger brake

Hey limited, lots of modern sportbikes have dual six piston calipers and have for some years.I have Hayabusa 6 pistons on my Triumph Sprint. And my S-2 with the dual 6 piston ISRs was a joy to stop. Bling factor was huge as well--combined with the 5 spoke Marchesini race wheel.

the dual 4 pistons is definitely more progressive than the single 6 one.
I have a PM caliper on my S1 right now, almost double the size of the stock Nissin, definitely improved stopping power, but not progressive at all, and dangerous!
it's like the on/off effect on the throttle of a bike, you risk to loose the control of your machine every second.
the qualities of the dual disc system don't need to be discovered or argued, there was a discussion about the side pulling effect of the single disc system right here not so long ago I don't wanna reopen, but again the dual disc system might not be needed, but you never know your limits in the street and the safety is never enough when you drive in the traffic!

Sleez is right on about the heat.
I can't tell you how many stock rotors i warped. I think last count was three. I then upgraded to a EBC race rotor...guess what...warped that one too.



I have not yet (!) completed my dual Brembo brake kit. I have all the parts. Just gotta find the time.
