I was thinking,...(Dangerous!) anybody know of anyone still selling the components for a dual disc set up? Maybe a part number list to put one together with factory parts? Anything like that floating around out there? | ||
| Sleez |
this one still listed, been lusting it for quite awhile!! http://www.yoyodyneti.com/ProductInfo.aspx?product id=150BU1320 | ||
| Brinnutz |
www.speed-of-color.de has some... It ain't cheap. | ||
| Rickie_d |
Sleez - Nice...But the pocket book screams Ouch!!! | ||
| Goldtooth |
put on a ducati monster front end | ||
| Dvc357 |
Man oh man. Well, the one company dosent have them anymore and as for the other, anytime you get close to a thousand euros,....it's too much. They are bad to the bone though! I still have to hit the lotto! Goldtooth! Have you seen one done before. I mean, is that just a concept or something do'able by a guy in his garage. | ||
| Nallac |
Goldtooth, have you got more info on the Duc front end swap... | ||

Gentlemen: You're going about it the wrong way. Here's how I've done two Tubers for friends, and not have had to deal with those Pirates (European or otherwise). First, understand that the Buell brake is a 6-pot Nissin caliper with 90mm mounting ears. It's just stamped with the Buell logo. These are available from Sportbike Solutions for $504 the pair, and yes, they'll sell you one for about half that....say $205 or so. I strongly recommend (no, that's not correct. It's required....don't ask me how I know) that you upgrade your master cylinder to a 5/8" axial or a 19mm radial. You can get good ones off eBay for about $150 new. Obviously, you'll need a brake line to tie it all together. I recommend a custom made Galfer, though a Goodridge or a Speigler will do nicely, and all are available pretty much anywhere. Shop carefully, and measure even more carefully....make sure you leave enough slack so that the bends in the line are nice and smooth. Sorry, I don't have the specs handy, so you're on your own. Cost: About $80. Now, you're going to need a rotor. That's a Nissin, too. When you have the thing apart, take your old rotor to the local Motorcycle salvage yard and measure it up for a match with what they have there. The place I use had about 3,000 rotors. Took me about 15 minutes and $25. You'll need rotor and caliper bolts, and I insist that you get new ones. American Sport Bike has them, I think. Put it all together, (Takes a coupe of hours. Don't rush it.) and you have the following: Caliper: $205 Master: $150 Line and washers: $80 Rotor: $25 Bolts: Inconsequential Satisfaction of You Doing It: Priceless! Voila! You have now saved half the cost, and used the same components that Buell uses. It's a no-brainer. DW | ||

My ebc race setup (single rotor) has never had issues hauling my butt down to a stop. Im not sure the extra weight is really worth it unless your tracking the bike. | ||

Good day Dragonwing, NOW THATS WHAT I'M TALKING ABOUT !!!!! I had suspected, and hoped, it could be done with stock parts but hadnt been able to find anyone who had done it. This will be my spring project!  I'm sure i can find most of the parts on EBay. I have checked my local salvage yards and they are worthless. If anybody knows of a better source then EBay for a Disc and Master, that information would be appreciated. | ||

Hey DW , I have a few ?? . first being do you have any pictures and second if your looking to save money why didnt you buy a used set of calipers off a bike that says they fit .ie gsxr 750 . wouldnt that work ? i mean i did a quick search and found caliper sets for $50 . even with a rebuild it would be cheaper to go about is this way . and correct me if im wrong but couldnt you mount an oe rotor on the other side ? thanks in advance . | ||
| Dragonwing |
D1: Though I'm quite well known as being.....ummm....frugal, I won't do brakes on the cheap. That being said, I believe that the ONLY other bike on which these Nissin calipers were OE was a certain Aprilia. The list that you see on the Sportbike Solutions site is a list of bikes that these calipers can be used as an upgrade.....and likely because the factory uses other calipers with 90mm mounting ears. Secondly, the calipers are absolutely Left or Right handed...they can't be flipped, but the rotor surely can. I just didn't have any rotors provided by the client, and had to source them myself. Lastly, in short, I don't mind paying for quality parts, but I do mind OVERpaying just to have someone assemble a half-assed 'kit' that I can assemble myself. Oh, and sorry....no pix. DW | ||

ok i mean i dont care if my bike has tokico or nissin calipers , dont worry ill go through an rebuild ,ive never had a brake failure due to rebuild so this will be my winter project , my main concern with the rotor as i dont have one infront of me is it dished in anyway ? | ||
| Dvc357 |
Dragonwing, Briefly, before i begin collecting parts. I'm sorry but you have to speak to me slowly as my alzhiemers is flaring up. Ok, the Calipers are unidirectional, dedicated to either left or right, and those can be sourced at sportbike solutions. (possibly JUST a left) Those are just generic 90mm mount, 6 pot Nissins. Rotors are bidirectional and i can just find a match to my existing stock right and mount it on the left. AND all i need are the parts you listed previously? | ||

 I got mine from American Sport Bike. REX | ||

DVC: You are correct that the rotors are bi-directional and that the calipers are dedicated left and right. Note that Nissin offers two sets of mounting ears for this 6-pot caliper--90mm, which is what you want, and 40-something mm, which will not fit. I offer this piece of wisdom in the event someone finds a set of Nissins on one of the auction sites. I've found that the 40s are significantly more likely to be had than the 90s, so be careful buying them. D1: Be careful mixing calipers. the Tokigos, while having the correct mounting ears, are not laterally the same width as the Nissins, and therefore will not bolt up to the factory rotor. Therefore, you'll find yourself shopping for a rotor with the correct 'pitch' to accommodate the different caliper. That's a hunt I don't think I'd want to undertake, as you'd have to mount the caliper, then measure extremely carefully both the relaxed and the working distance of the caliper from the hub, and then subtract the width of the rotor you don't have to make sure it slots into the caliper. Seems like waaay too much cobbling for my tastes. DW | ||

Dragonwing: One last question for now. Master cylinders! Any work better then others? Or any you might recommend for me to look out for? (Better stopping, ease of mount, ect.) Rex: That perimeter brake looks cool, but American Sport Bike reports that the manufacturer dosent make them anymore and they no longer carry them. | ||
| Rex |
Okay. I believe it was Braking that made them...REX | ||
| Dragonwing |
DVC: Feel free to ask away! My opinion of master cylinders was modified with the purchase of my ZX14. Until that time, I thought that an axial master was perfectly fine for any application. And I suppose that it really is...to a degree. Since riding the 14, and my brother's ZX10, I've become a fan of the radial masters, as, in my humble opinion, the radials allow better brake 'feel.' That is to say, I'm able to better modulate the amount of pressure I want to apply to the disc, because I get more feedback from the caliper. It's a matter of preference, I suppose, but I'll go out on a limb here and say that any name brand radial master will suffice (Nissin, Tokigo, Brembo)...just be sure you get at least a 19mm one. Less than that won't give you enough push for both calipers....much larger is just overkill, with no real performance increase. DW | ||

Some of the Buell racers used the Showa lower fork legs off a GSXR to get the dual disc mounting. You could just have some adapters made to bolt on some from another bike. | ||
| The_italian_job |
yes, it was Braking that made that system and it's no longer available. I wish it was though... I searched everywhere, even in Italy and I managed to find one new. they guy was asking 2500 euro and they were fighting to get it!!! I decided for a better system for my S1, double Brembo monoblock from Ducati...    it works better than any other system available and you can buy what you need used on eBay, saving actually some money... | ||

Dragonwing, how'd you think 4 pots would go instead of the 6's. Reading the sportbike solution page the "only" bike fitted with them from factory was the MV 750f4. Reading there list of bikes that you can use the 6pots as updates,could you not use one of the corsponding bikes twin 4pots instead of twin 6spots?. | ||
| Dragonwing |
Nallac: Though I haven't tried it, it seems, in theory at least to be a good way to go. I just kinda wondered what rotor diameter those other bikes were using along with the 4-pots. I would seem to me to be easy to try out for fit,without having to spend a lot of jack for the 6-pots. If you do it, let me know what you find out. DW | ||
| Jayvee |
You guys look at this one? http://store.sporttwin.com/product_info.php?cPath= 49&products_id=252 | ||
| Nallac |
Dragonwing, most of the others using the 4 pots have quite thin Rotors eg, a workmate has a 98 ZX9R which suits the "SBS" 6 pot conversion,at a guess Rotors would be 3mm max. But checking out the specs of the 6pot caliper vs the 4pots, they have the same measurement mounting face to middle of caliper(26mm). So in theory i can't see why they shouldn't(couldn't) work?...... and a hell of a lot cheaper and more plentiful. Just need to get to a friendly wrecker and see.. What size M/cyl to run with 4pots,if i go this way?. (Message edited by nallac on February 27, 2010) | ||
| Dragonwing |
Nallac: Again, because you're now running two rotors, two lines, and having to push larger pistons, I'd still highly recommend the 19mm radial. Larger is too large, unless you're strictly going to race it. DW | ||

I have been spying on this thread, especially ever since I recently got 2 new 100 dollar rotors. So for the hell of it I went and tried to line up a left 90MM Tokico caliper shared by the pre radial ZX12 and hayabusa and they do not fit, the body of the caliper is much deeper than the stock nissin and it hits the spokes on the inside. They are at least 1/2 inch too deep. The mounting bosses are correctly spaced though. | ||
| Dragonwing |
That's what I was afraid of, and had shared this same concern with another member off line. Not only are the spacing of mounting ears critical, but the depth of the caliper and where it slots the rotor is going to be a major issue. DW | ||
| 12mpghwy |
What it means is that we would need a nissin caliper. Most likley any caliper that takes the same pads as our tubers and came one a bike made around the same time would work. So that's mv augustas And a very few Asian bikes. |
