I got the impression that the 8-piston caliper on the 1125R fits the XB, bolt on. While the front rotor is the same for both the XB and the 1125R So my question is simple : Will BUELL consider offering an upgrade brake kit (like the race kit)for the XB, consisting of the 8-piston caliper+ master cylinder??? I think that will be great for all of us, XB owners, since the XB will definately benefit from stronger brakes with less brake fade under hard use. Also it would be great if the factory, offered the "brake kit" at a low price, lower that the standard profit for spare parts. | ||

Why not use the XBRR that bolts up. I believe you can also get the master cylinder as well. | ||

The 1125R brake caliper will bolt onto a XB. You need to change the master cylinder to keep the leverage from going into the half-a-finger range; the XBRR master cylinder is a possibility. The 1125 caliper is priced less than the XBRR unit originally was now that Nissin has them in mass production. | ||

What is the size of the master cylinder of the 1125R ?? Is it 14mm or greater ?? | ||
| Diablobrian |
That is good news. The price of the 8 piston caliper was a little on the steep side for me to justify it before. Anyone know what the new price is for the brake caliper and master cylinder? | ||

To Anonymous. First of all, thanks for answering. The bolt on of the 8-piston caliper on the XB is Great News. I hope BUELL understands the importance of the performance of the brakes on the 1125R!!! The XB brakes are "poor" compared to systems found on bikes like the R6, CBR, Ducati, etc. I just came back from a ride, and once again I felt the brakes on the XB are weak and fade after hard use. What a dissapointment, for an otherwise excellent bike!!!! Actually sometimes I feel the brakes to be dangerous!!!!!! So, I tell to the Anonymous this.... I will try the 8-piston caliper on my XB. Unless I am happy with the performance ,I am not considering Buying the 1125R. I do not care if the ZTL or ZTL2 is a BUELL trademark. If it is not performing, it makes no sense, just being different!!!! BUELL should give XB riders the chance to upgrade the brakes, at a relative low price. Sell a brake kit for the XB, including the 8-piston caliper + master cylinder. Convincing the XB riders that the ZTL2 is actually working as well as the system on a CBR, will be a strong reason for sport riders to go for the 1125R. I seems that people are concerned about Hp, torque curves, imperial or metric bolts, valve adjustment intervals, and are ignoring the point that in my opinion is the weak spot of the XB, and the point the 1125R should definately be better.... BRAKES I hope the factory is listening to this. | ||

I have heard very few people complain about the XB brakes. Including magazine reviews. It is interesting to me that you consider them to be almost dangerous. | ||

Vag, Maybe you should consider a CBR if you are so impressed by that bike & believe the Buell brakes are so "dangerous". | ||

I wonder if it is something to do with the brake pads used, break-in proceedures, or maybe a system in need of bleeding. I'm currently using EBC HH "kit" pads on my bike and I find the brakes beyond adequate for street use, and I don't use a rear brake at all. I removed it due to physical limitations, and am working on a thumb operated master cylinder for the rear. If I were not addicted to performance upgrades, and working towards doing track days in the near future I would be perfectly happy with my XB's brakes. I am a former GSXR, ZX7R and VFR owner so I have a broader perspective than a lot of people. I will admit that I did not care for the initial bite and feel of the stock pads, but that was easily remedied. | ||

@Vagelis46 i use EBC HH pads and Castrol SFR brake fluid - no fading, not on the road and not on the racetrack! i think i don´t need the 8-piston-caliper ... but a radial master cylinder (MAGURA Radial 190) would be great... in the near future.  | ||

Yeah uh... bleed the brakes, replace the fluid, hone the rotor, swap the pads and make sure you bed them well. THEN tell me the brakes are dangerous or even "poor". All of that said... I've faded the ZTL brake as well. Swapped pads and the issue went away completely even when I was out running them just to see if they would fade. They did not. I don't mean to rag on you but you need to be CERTAIN that it's not YOUR brakes that are wonky as opposed to the "ZTL System" being wonky. I mean really... how many races have been won with the ZTL setup? Either you are riding harder than a racer winning a race or YOUR ZTL SYSTEM isn't working correctly. | ||

As an aside... why do you want the swingarm to be mounted to the chassis? | ||

Vag, I had the same thoughts regarding the brakes. I thought they were weak and then they started to shudder. Egads! My dealer replaced the rotor and I swapped out for a set of Lyndalls. Night and Day. For day to day riding the stock brakes are more than adequate. Where they begin to lack is when we, like the idiots we all are, begin to ride our street bikes on the street like we were on the track. I believe then that the stock pads are not as adept. Upgrade your stock pads, replace your fluid with the higher end stuff, bleed 'em, and I'll bet 95% of your concerns disappear. Mine did! Upgrade to the 8 pot if you like, but I think you will find the upgrade mostly superfluous. | ||

Vagelis46, it's your brake pads, or maybe some air or water in your brake lines. | ||

I'd love to see a Buell Accessory brake upgrade kit. I would include the 8 piston caliper, a more aggressive pad compound (if you think you need the 8 piston, then you will want more aggressive pads), and a new master cylinder. Directions should be easy enough to do. And sell the kit for a discount over buying all the parts seperately. Buying the kit would keep your warranty intact and would be engineered to all work together. --Sean | ||

""Vag, Maybe you should consider a CBR if you are so impressed by that bike & believe the Buell brakes are so "dangerous"."" I do not like IL4 Jap bikes. I LOVE my XB. I just think that there are some areas (definately the brakes)that can be improved. Is this bad. The fact that Buell owners can talk to the factory is GREAT! Why not take advantage of it and tell them our thoughts, and problems and ideas??? I use EBC GFA kit pads + 14mm master cylinder + OEM rotor, BUT....Just ride a Triumph 675, and compare that brakes with my XB.....It is sad! I am sure the front end + chassis of the XB can handle the extra brake forces. I think the chassis is one of the best in the moto industry I hope the 8-piston caliper with the increased contact area, should improve the brakes dramaticaly. As I said, I will take no risk with buying the 1125R, unless I am sure the brakes are TOP staff. I would like to try the 8-piston caliper on my XB!! Buell advertised & sold on the www.Buell.com, race exhaust & ECM for the XB. I think the "brake kit" for the XB should be introduced at www.Buell.com. It is similar to the introduction of the bronze oil gear that was developed through racing and introduced to us as an upgrade (I "managed" to make the steel gear fail at 5000 miles after buying the XB). Since the 8-piston was developed in racing, it could be mabe available to the XB owners, as an upgrade. The XB would definately benefit. I would buy it, for a reasonable price!! Brakes are far more important than an extra 5Hp. | ||

Ya gotta maintain your brake system if you expect it to perform well. | ||

Regarding ZTL, the XB's brakes, and magazine tests that push the bike to its limit... UK's PB magazine tested an XB12SS at Nurburgring, against Yamaha MT01 and Ducati GT1000. They found the XB's brakes dissapointing. They said "No power and tendency to overheat rather quickly" But overall they really liked the bike, and thought that its corner ability was fantastic! So it is not only me and a few others on this board, but also magazine testers, that find the ZTL not so good, and sometimes "dangerous". I want to check the ZTL2 on my XB. I think the underpower issues will be solved, but I have doubts about the overheating. The 1125R will be tested on racetrack against the best of the sportbikes. It would be dissapointing to give problems with the brakes. | ||

"Brakes Overheated" ? ______________________ The ZTL brakes will run hotter, and this will expose set-up issues. The stock pads are a compromise between performance and longevity, and will not stand up well to the heat of hard riding. Aftermarket pads that can take the heat may not last long, and sacrifice longevity. The pads aren't the only thing affected by the heat, but first things first. _______________________ Dual front rotors offer more pad and rotor surface area, and will handle heat better...at the expense of 4 additional pounds of weight...for an item that has to deal with F=ma constantly. _______________________ Pick your poison? | ||

I'll take the well bled ZTL with EBC "HH" pads or a ZTL2 please  . | ||

Tell me about how you invision the kit. . . parts . . . documentation . . . how you'd package and market it. Market it through the Pro Series line as above with the caliper, MC, brake line ( if required ), and much more aggressive brake pads, since the users of the kit are likely to need them. Or, sell the kit less pads and offer several pad options. Repair pars should also be available through Pro Series. Documentation could be as simple as cuts from the Factory Service Manual with some simple written instructions. Chrysler supported their racers and street performance enthusiasts through the "Direct Connection" program with factory engineered components and parts kits ( ie: electronic ignition retrofit kits, suspension kits, etc. ) Most of your Mopar Racers are the "Rather Fight than Switch" types because the factory provided that support. PS, Please make the fastener safety wire-able... . |
