Every other manufacturer manages (both OEM & aftermarket) it these days so I can't see why Buell cannot do the same and give us a full stainless system. Micron Hydroform stainless steel all the time. Micron hydroforms their headers, let's just stick to mufflers, and the very complex shape of the 1125's muffler. Almost all OEM and after market Japanese cans are round or oval. Not that hard to do with almost any metal.  For one second let's break down what makes steel. Iron and carbon. The more carbon you put into steel the harder it gets, IE brittle. Try bending High carbon steel into a complex shape. ::SNAP:: OK let's break down stainless. Iron, carbon and chromium. Yes chromium is the same stuff used to chrome parts. Ever played with a piece of flaked off chrome? Snaps pretty easy right. Ever heard the phrase Hard as chrome? For a lack of better words now your stainless is about equivalent to high carbon steel in it's brittleness. That is why Stainless nuts and bolts have low grade of 4 or 5. SO take said sheet of Stainless and try to hydro form it into this.  While I am sure they could have hydroformed half shapes, and welded them together, this would have weakened the structure and left more welded area that could casue leaks, fatigue and possible failure as opposed to the amount of sheets and welds used now. Plus do you want the price to go up a few extra hundred dollars for something you may take off anyway  | ||

SOME people will take it off anyway. This is a good way to FORCE people to take it off. As for me, paying a few hundred extra at the beginning is better than paying it REPEATEDLY during my time of ownership and the time lost while the bike is down. | ||

That is one weird looking pipe. Please stop the pics.  . I want to remember that I liked the bike in person when I was on it, riding.  | ||

Well put Spidy ! nuf said on this.......put it to rest already.....or not (Message edited by bobup on October 26, 2007) | ||

BTW the coating on this pipe is not the saem on the old XB's Also this pipe has jack points like the XB | ||
| Jaimec |
All right, I'll hold off complaining until I see how durable the new coating is... | ||
| Reepicheep |
And I just noticed... no straps! That's cool! Cheaper and one less PITA for overall cost of ownership... | ||

It'd be nice if the rear brakeline tab was bolted to the swingarm in the photo bike...LOL. | ||

Here's a contest for the sharpest of the bunch: Name the ten things in spidey's muffler picture that are not production representative (not counting the brake line clamp - d'oh!)  | ||
| Spiderman |
LOL guess mine | ||

I'll let you know once I get my 1125 in my garage..........second week of November?? | ||

Name the ten things in spidey's muffler picture that are not production representative Just my guess  | ||
| Coal400 |
I don't have one yet, but this is as good as I can do... these are my guesses. Clutch cover (angle of clutch port different too) Clutch line/hose The sensor (on case by the lower balance shaft) The 1125 Logo is different Rear coil/shock Fastener on the engine mount/pivot (will be black) Fastener on the brake pivot (will be black) Braided cloth cable jacket on wires will be gone. Heatshield will be different The exhaust muffler is also be slightly different. I've seen 2 different mufflers on the 1125R so far, not 100% on this on. | ||

Slow start to a Saturday... I'll take a stab  Z | ||

Someone asked about the durability of the coating. I can not speak to coating used on the 1125r muffler as I do not know what it is. However, I've had my XB muffler ceramic coated because it was rusting. This is not ceramic like a flower pot is made of. We had to use a hammer to beat the muffler into place when we put it back on the bike. Not hard, but we were hitting it with a hammer. It did not chip. If they are using a modern ceramic coating on the 1125r muffler, it isn't going to rust. | ||

Looks like the old "milspec" finish used on many military weapons as well as many civilian guns. Its very durable and quite rust resistant at least from the outside. | ||

Ever played with a piece of flaked off chrome? Snaps pretty easy right. Ever heard the phrase Hard as chrome?" Interesting theory, but wrong. There are plenty of stainless steels with very high ductility that allow forming into complex shapes. The likely reason they didn't use SS, is to save money. Stainless is very pricey these days because of alloy costs - nickel is through the roof. } | ||
| Spiderman |
Not a theory BTW Yes you can get stainless with high ductility, but! The more ductility you have the less chromium you have, which means the more prone to corrosion the stainless is. Also, it wasn't said that stainless could not be bent into complex shapes, just that the cost to do so would add too much to the cost of the pipe. | ||

"Not a theory BTW Yes you can get stainless with high ductility, but! The more ductility you have the less chromium you have, which means the more prone to corrosion the stainless is." Give it up Spidey - this is totally wrong. You need 12.5% chromium min to make steel stainless.} Any of the 300 series stainless steels have enough chromium to prevent corrosion and more than 40% elongation. Take a look at your typical SS kitchen sink. Steel is my business for the last 30 years or so. | ||

Sorry Diablo, but kitchen sinks (!) and underslung highly shaped welded mufflers with a rather warm catalyst do not compare to one another. Lay off the arachnid. He's pretty much correct. | ||

Anonymous: Are you an engineer? Does BMC have any metallurgists on staff}? Perhaps you could discuss this with them? I'd be amazed and shocked if you found a plain carbon sheet steel to make the muffler, but couldn't find a suitable stainless steel. | ||

Anony - sorry about the clamp comment. I have an eye for things like that...they usually pop up after I work on any of my bikes, LOL! Drop it out completely and it's another, what...25g of unsprung weight conquered?  | ||

Yep, Buell has some of them thair ainjineers on staif. Purty shore we gots on of thaim meteelargists, tu, nmaybe evn more than one. Being as Pixsburgh was Erik's home town, he ain't to shabby 'round meteels aither. You say that staynuss steel is just as easy to form as mild steel? How long you benn wayrin shues, there, Diablo man? | ||

Micron have been making Hydroformed exhausts for some time in stainless steel. Here are a couple of their latest offerings for the CBR600RR and R6. Both are fully hydroformed and stainless steel. Not only is it possible but these are not particularly expensive either.   | ||

That top pipe reminds me of a leech. | ||
| Killakella |
Could'nt you make the whole thing out of vacuum formed pre-preg carbon fibre and incorporate a belly pan as well, or would it melt? Trojan? | ||

Carbon mufflers don't last too long, especially when fitted to big twin cylinder motorcycles. They are susceptible to heat and can become brittle with exposure to intense heat (This is why we don't sell any carbon sleeved pipes for Buells). Carbon sleeved mufflers still have to have steel internals anyway, so it wouldn't be an easy job to do unfortunately. It would in theory be possible to make a full carbon muffler/belly pan as given enough time and money you can make anything from carbon these days. The expense would be huge and it would be extremely difficult. It would also be very unlikely that it could be made to comply with all of the noise & emmission regs in force now. | ||
| Killakella |
Thanks Trojan, So I suppose we will have to wait for Micron to come up with something.  | ||
| Spiderman |
Funny, I don't see any rivits on the1125's muffler and those muffs don't look to have cats in them... Kitchen sinks?!?! Don't even get me started on wall thickness. I keep trying to compare apples to apples but people keep throwin oranges into the mix.  |
