I thought it was just the same ducting from the 1190RS... http://www.motorbeam.com/bikes/ebr/the-astonishing -brakes-on-the-ebrs-1190-superbikes/ I was reading the thread started by Hughlysses(http://www.badweatherbikers.com/buell/messages/253 912/734450.html?1395230571) and started clicking around. | ||

It is to be duly noted that this massive disc doesn’t have any slots for heat rejection but has a couple of ducts for that purpose. The ducts are connected to a vacuum pump and are placed near the disc itself. The vacuum pump is coupled to the timing belt of the engine; vacuum is created by the pump in the ducts and air is sucked which eventually cools down the disc. No doubt that coupling the vacuum pump to the engine will reduce the overall power; on a lighter note we would say that the designers were biased towards the braking system. Read more at http://www.motorbeam.com/bikes/ebr/the-astonishing -brakes-on-the-ebrs-1190-superbikes/#6gd4z6sfFljgF 9IE.99 This is complete and utter bullshit. | ||

I concur with Jdugger, there are NO vacuum lines going to the calipers or anywhere else in/on the front, or rear brakes for that matter. They are both fed by a beautiful steel braided line and that is it. | ||
| Hughlysses |
LOL. I just posted an article (in the EBR in the news forum) by the same magazine on the history of EBR. It seems to have some similarly skewed "facts". | ||

Seriously? A vacuum pump on the brake system? Are you a COMPLETE and TOTAL MORON? I see you attended the MVGR College of Engineering, did you sleep through the classes? | ||
| Hootowl |
There is no timing belt either. It's a chain. | ||
| Hughlysses |
Dean- you've got to figure part of the guy's problem is likely the language barrier. He's probably having trouble understanding what he's read about the bike. He is at least trying to say something positive about EBR. | ||
| Midknyte |
isn't he additionally a bit handicapped by having a background in the automotive industry? | ||
| Hootowl |
English is the official language. Indians speak it from childhood. This is not a language barrier issue. Besides, there isn't any possible way to misinterpret a cooling duct for a timing chain driven vacuum pump that sucks air across the brakes, at the expense of some power robbing parasitic losses. He's just making shit up. | ||
| D_adams |
I'll run with that statement right there. | ||
| Court |
On the bright side . . . . . it's as factual as that "History of Buell" article someone posted the other day. | ||
| Hughlysses |
^ It's the same magazine, if not the same author. Perhaps someone at EBR could send him some press materials to help straighten him out? | ||
| Natexlh1000 |
Oh yessss. http://www.motorbeam.com/author/nischal/ Don't try to correct him! We want him to make more! | ||

Hello people this is Nischal. The guy whom you are talking about. Coming to the 1st point: I saw the bikes first in Auto Expo 2014 and interacted with R&D engineers of Hero MotoCorp. You all must be knowing that Hero MotoCorp has bought EBR. So the content that i wrote about the brakes was told to me by one of the company's R&D Engineers. So that is the reason I believed the information to be correct and wrote the article. Vacuum Pump , timing belt etc each and every word was uttered by that R&D Engineer and nothing was my assumption. Now coming to History of EBR; i compiled information available from Wiki and wrote it down. | ||
| Hughlysses |
Nischal- welcome to the forum. Sorry for faulting you for facts you got from a faulty source. We're very aware Hero MotoCorp owns ~49.5% of Erik Buell Racing and we realize their influx of cash is going to make a HUGE difference in what this company accomplishes in the future. The Buell 1125R motorcycles had a vacuum assisted slipper clutch; I'm not sure if that feature was carried over to the EBR 1190RX or not, but I wonder if that is not the source of confusion about the braking system. As I said in my post above, I think we all appreciate someone like you in the Indian moto-press saying something positive about EBR, even if it was not 100% accurate. There is a wealth of knowledge here about the history of Buell and EBR; I'm sure people would be willing to help you out in the future. (Message edited by Hughlysses on May 08, 2014) | ||

So basically, you don't have the technical knowledge to know if what you wrote was true; and, you didn't validate your facts. Did I get this correct? | ||
| Ratbuell |
Find a copy of this, it's MUCH better than Wiki: http://www.target.com/p/25-years-of-buell/-/A-1163 6995 | ||

You all must be knowing that Hero MotoCorp has bought EBR. Welcome Nischal- This crew are a sticklers for accuracy and they have the memories of a heard of elephants. To be clear HERO did not BUY EBR, they invested in it by purchasing shares of EBR, 49% to be exact. I am certain you misunderstood what you were told by the engineers as from a technical side you can see it doesn't make sense. Any how welcome just be aware the fact checking flame throwers are at the ready to... help... you edit your articles.  | ||
| Hootowl |
"Did I get this correct?" Sounds about right to me. It would be very difficult to argue otherwise. | ||
| Fuzzz |
Dang it! Another Phantom post by Court.... | ||

@Jdugger - I work in automobile firm and I am well aware of technical stuff especially related to engines.That is the reason I was keen knowing the system. What he said was actually very convincing. Basically I work on engines that goes into cars/LCV's and Trucks. Hence that belt drive thing looked good to me. Coming to Vacuum pump, I know its functionality and how much it effects the vehicle performance. That is the reason i wrote in my article saying EBR engineers gave more preference to braking. Coming to validation of article : EBR is not a common bike (atleast in INDIA) such that this thing can be validated. And btw before publishing i did various search but no-where proper information was given about brakes. All websites just gave basic information. None in detail. Another small setback for me is that search engines don't actually direct me to USA or UK or Western published links. They hardly pop. there may/maynot be websites that explained the raking system of EBR. It either didn't get into my radar while searching or i must have overlooked. From next time I want any info on EBR i would contact this Forum. I hope you people would help me to clarify some facts. Can I expect that? @Ratbuell - Thank you . But basically everyone believes WIKI to be right, right?. I am not defending WIKI but all I am saying is that matter in wiki is taken as granted.) Just one question and don't take it as an offense, Who has authenticated the facts in the article? ( the link you posted) @Classax - Fyi HERO owns 49.2% shares (EXACT) in EBR not 49%. I just used a common term for buying. From next time I will make sure that i use ACCURATE words. Thanks for correcting. And yes I believe in posting correct information rather than misleading ones. I have already told my editor to remove that article on brakes. It should be off in a couple of days. I am open to take inputs from people. That would in fact improve the quality. Thank you for your encouragement. (Message edited by gadnischal on May 09, 2014) | ||

We will be happy to help you fact check here in the future here on badweatherbikers, we stay pretty close to the factory developments. | ||

The link I posted is to a book, written by two of the "founding folks" of Buell and close personal friends of Erik Buell. Dave and Court were there, and a part of the Buell history, right from the start. Their account is taken at large as "the bible" when it comes to things Buell related. It is truly a firsthand account. And unfortunately...no, not everyone believes wiki to be correct. At least, not those of us who like to research and fact-check our information. Smart folks see it as a good starting point, and a way to identify true sources of information such as badweb, or Court and Dave's book, or even the EBR staff if the need arises. Buell / EBR is a very close family. I am currently restoring a limited-production Buell from 1998. 12 of them were built. I have, through this network of friends, located the original source for the body decals as well as a wealth of production and build information to help me with my rebuild. For a sixteen year old motorcyle with a total production run of 12 units. I believe I speak for everyone here (including Court, whose post I hope you had a chance to read before he removed it last night) when I say you have lucked into possibly the best source of Buell and EBR information and passion there is, with the possible exception of factory staff...but even they pop in here from time to time as proud parents, just to share the joy. Welcome, and please don't hesitate to ask if you have questions. (Message edited by ratbuell on May 09, 2014) (Message edited by ratbuell on May 09, 2014) | ||

> @Jdugger - I work in automobile firm and I am well aware of technical stuff especially related to engines. > That is the reason I was keen knowing the system. What he said was actually very convincing. But, couldn't you have just taken a 2-second look at the brake caliper and known this was utter BS? I not trying to be difficult here, but I am struggling with how someone with even elementary automotive knowledge could have been fooled here. This isn't a dark technological secret there -- there's but two bolts and one brake line holding that thing to the bike. > Basically I work on engines that goes into cars/LCV's and Trucks. > Hence that belt drive thing looked good to me. What belt drive? Is there a belt *anywhere* on an EBR, even 'inside' the motor now? I don't think there is. > Coming to Vacuum pump, I know its functionality and how much it effects the vehicle performance. > That is the reason i wrote in my article saying EBR engineers gave more preference to braking. And, I'm still struggling with how someone with even basic automotive and fact-checking skills missed this one! There's no vacuum pump on these bikes, either, at least that I'm aware of. They are using off-throttle decel throttle body vacuum to slightly disengage the clutch -- a time-honored Rotax trick, really -- but that's it. The brake on the EBR is certainly unique, that I will give you. It's required a lot of engineering effort to get performance out of it comparable to that of traditional 2-rotor designs -- that's well documented. But, I'm really not sure I'd say there's a preference to it over the motor. That, too, has improved tremendously from the 1125-era. With just 65cc more displacement, the new EBR is putting down an additional ~35HP. Not a small change! |
