For those who might know the answer. Wouldn't it be better to have the rear brake on the opposite side of the exhaust, especially since the exhaust is almost directly in front of the rear brake? I am worried that there could possibly be some heat and residue issues with this design. I hope this was not a stupid question. Bare with me, I am a sport bike rider newbie. Thanks | ||

Rear brake? What's that for?  Brian | ||

I don't know. Myself, I'd rather it blow on the brake than the belt. I just want a pair of slip-on turn-outs. BTW, mine aren't lined up. One points right at the disk, the other points outboard a bit. Maybe 10-15˚ difference. Z | ||

Looks like an approximate 30 degree angle would ensure the exhaust gases clear the brake/swingarm if Zac4mac's 15 degree construction variance holds true. If the alignment/angle tolerances, both tip to tip as well as tip to centerline, can be held tighter 15 degrees would probably due. Slightly off topic but exhaust related, Has there been any tire heating issues? The muffler body looks a fingers width away from the tread. Gave me some concern when I noticed it on one the other day. To finish up, hello everyone. Occasional lurker here since the 1125R announcement. Thought I'd join so I could ask any questions that arise in my consideration of the bike. | ||

Ever noticed where HD exhaust typically dumps right next too? | ||

When she was warming up yesterday morning, the exhaust was blowing right onto the disk. Quite the cloud, never seen a bike do that. It was 22˚F Must be the water cooled part. Fumes don't hit the tire. Z | ||

Ahem....May i please be the first "Negative nelly" to muck up this thread? ...I'm just thinking of something really like a personal attack or other miserableness of a sort......It ain't coming to me...right now...be warned | ||

Zac: At 22deg those things happen. Given the right condition my ST13 with Staintunes will blow "smoke rings", just like some of those old commercials. Enjoy the 60deg today, Xmas we may have a dusting, oh no!!! Neil S. | ||

We've got snow coming in over the mountains right now. My driveway is a sheet of ice, courtesy of the snowmelt off the roof. They are saying snow on the flats around lunchtime. I'm driving the Camaro today. Loretta's gonna stay in the garage and get a sponge bath later. Z | ||

Archangel, there's never such thing as a stupid question they say. I don't think that's true. When people come up to you asking what time it is while looking at their own watch. That's a stupid question. Meanwhile back at brakes, exhaust, etc... There is quite a vertical and some lateral offset between the exhaust nozzles an the caliper. More importantly, fore aft distance and the turbulence in that area when the vehicle is in motion would greatly dilute exhaust gases. That's just my shadetree analysis of it all..  | ||

Hey Asbjorn, how's she running? You got "break-in miles" yet? I am a little concerned about condensation on the disk while she's warming up. Granted, once you're moving, it shouldn't be an issue. I'm going to try and put a lump of something in the pipe-tip to see if I can direct the exhaust internally. Works for rockets. Z | ||
| Doerman |
She's a dandy, I tell ya. I'm at 220 miles as of this morning. I'm guessing I'll be at 600 or so after this weekend. Be careful with that nozzle steering mechanism. She's a powerful thing, you know and might be veering to the right all the time if you put it on. Or that could be the constant sidewind on I-25 up to Cheyenne.. Dunno... Cheers Asbjorn | ||

The word from Buell is they have noticed no loss of performance of the rear brake due to this design. I think simply using your rear brake will generate more heat on the disc than the exhaust ever will. And with the front brake being so amazing on this bike you really dont need the rear brake. I never touched it once when I was riding on Laguna. | ||

Sometime . . . ask Erik Buell about how he handled the question from TuV? Perhaps one of the best Buell stories of all time. . . 1313 perhaps you should post the photo.  Remind me to tell you sometime . . . The exhaust pointing on the rear brake falls 3 notches below global warming on my list of things to worry about. | ||

I discussed this with my local dealer the other day while drooling on the 1125R. The exhaust does blow on the brake and coats the rear wheel a nice shade of black. I am thinking the aftermarket will probably address this situation as they develope mufflers to fit it... | ||

Don't worry about the exhaust, for heaven's sake. It is not an issue; if it was we would have done it differently. The heat is already fairly low by the time it leaves the muffler; with the swirl and dissipation of the gases with ambient air,you are talking about a few degrees above ambient at the disc, and discs work fine all the way up to where they are glowing!!! We have huge amounts of test miles and data on this bike. If you just ride them and don't modify them, life will be good! | ||

"and don't modify them," You jest?! Sounds like BMW before the new guys took over! | ||
| Anonymous |
Well, I'm not saying don't modify them, just that life will be good if you don't.  Especially if you just like to ride, ride, ride. If you do modify, well it all depends on what you, or the aftermarket guy, or the modifying tech truly know. Life could be good, or not. Of course, some like tinkering more than riding, so it might be good anyhow. Me, I'd rather ride. | ||

Thanks for that info Anony - Guess I'll not worry about the exhaust and ride my 1125R every chance I get. Set aside a big area for us at Homecoming. Z | ||

Ok... no heat issues for the rear brake, but still a lot of cleaning for the rear wheel... After riding the 1125r (behind my 98 S1W with a V&H muffler), all I could think of was the S1W sure sounds sweet!!!!! I like to ride, but I like to hear what I am riding!!! If I were to purchase an 1125r, the only mods planned would be increased air flox, a muffler and some cosmetic things... which is the same thing planned for my 08 12r!! P.S. Did I mention I like to play the drums?? LOL The wife is on me to get "one of those sets you can plug headphones into"... LMAO | ||
| Old_man |
Test it. Put your hand behind the exhaust-it's not that hot. | ||

"Ok... no heat issues for the rear brake, but still a lot of cleaning for the rear wheel..." Right, cause otherwise the rear wheels on motorcycles never need cleaned. Well unless you count the brake dust and road grime that begin to accumulate as soon as you leave the wash bay. People sure are funny. | ||

Blake, You have it all wrong dear sir. I am not funny, I am funny looking!!! LOL | ||

Some slip on turnouts would be great. Or if you live in Nebraska where its freezing you could just use a rubber hose and pipe the exhaust into your pantlegs for warmth. I think thats why there is 2 outlets on the muffler. Problem solved. | ||
| Zac4mac |
Fugging Brilliant Darkice!!! Would have been nice today, got 140 miles(500 so far) and the WARMEST was 36˚F towards the end. Z | ||
| Archangel_g |
Thank you for the answers. Nothing to worry about then. Good. | ||
| Baggermike |
Hi guys, I have given this some thought and have come up to this conclusion, would you want it cooking your belt? or up high cooking your ass? plus the design of buell bikes is all about keeping the weight low. Mike | ||

I have noticed when warming up the 1125R in the cold that the exhaust creates condensation which collects on the rear brake disk. This causes the rear brake to make noise for a bit until it's no longer moist, but otherwise is not an issue. I do, however, dislike how much black carbon is deposited on the rear wheel. That stuff is hard to get off! I saw someone modify the exhaust outlets to bend outward. I would like that or something like it. I'll keep an eye on the aftermarket exhaust developments though... Someone might produce something nice. I'm not sure that I like the D&D slip-on. |
