I haven't seen this on here but at the bottom of the article says the source is bad weather bikers..... http://hellforleathermagazine.com/2010/11/erik-bue ll%E2%80%99s-latest-patent-combines-exhaust-swinga rm/ | ||
| Cityxslicker |
sweet, that would get the 'custom' exhaust nazi off the mark The science, I don't understand, it's just a bike I want to ride all week  | ||
| Court |
What makes them think that is the "latest" patent? | ||
| Not_purple_s2 |
Cool! Great Find. Wonder if we'll see that on the new 1190RS? | ||
| Not_purple_s2 |
Can you imagine having the confused looks on the faces of Cali Highway Patrol trying to figure out where your exhaust is. | ||
| Firebolt020283 |
I haven't seen it here either but it sure is a neat design although it does not leave much in the way of aftermarket pipes. | ||
| Froggy |
Latest that they know about.  | ||
| 86129squids |
Very interesting, very cool. Wanna see more! | ||

Wouldn't that increase unsprung weight? | ||
| Hootowl |
Article says it is negligible according to the engineer they asked. | ||

I guess they already licensed it to Confederate? Because this bike has been out a while with a combined exhaust/swingarm... http://www.confederate.com/cm4/f131hellcat.php ac | ||

Wonder if we'll see that on the new 1190RS? Don't know, but I wasn't all that excited about the tiny snippet view of the exhaust we saw in the "teaser". This would look better. Looked like the teaser had a version similar to the MV triple. That was awful looking! It will take folks a while to get used to a swing arm exhaust system. I'm sure it will be met with the same skepticism as the under slung exhaust. | ||

Cool! Good reporting, and turned around FAST! | ||

So does this mean any patent awarded to Erik after the closure is his outright? I [edit] THOUGHT I looked up the patent and it still showed the assignee as "Buell Motorcycle Company". Just re-checked and I can't find the damn thing now. (Message edited by Hughlysses on November 22, 2010) | ||

| Avc8130 |
While they are not the same design, I think claiming NO resemblance is silly. If Confederate wanted to cost Erik some money they might be able to make a claim that they had the concept first. Same goes for Erik if he has documents that pre-date Confederate's production. In the grand scheme of things, I don't think either cares what the other did since their markets are so different. Confederate did it because it is badass tough. Erik is doing it because he sees it as solving a barrier to all out racing performance. ac | ||

I thought this was funny Sources: Bad Weather Bikers from bwb to hfm back to bwb. I think it will be like the under slung, every body laughs at it says it's stupid then steal the idea. I have friends that still say it's stupid then I ask why kwahondaha all use it now.. | ||
| Cataract2 |
Would hate it on the street. Could you imagine wanting to change exhausts with that? | ||

"I thought this was funny Sources: Bad Weather Bikers from bwb to hfm back to bwb." Hey, we just like to keep it in the family. | ||

"Those two systems don't even resemble one another. No issues." 1) "A nicely-designed cruiser from New Orleans employed a flexible pipe made from a nickel-chromium alloy called Inconel to similarly channel its exhaust gasses through a swingarm." ( That would be the Confederate Hellcat ) 2) From my read of the patent abstract, I think it would be quite a stretch to say that the Confederate does not fall under the patent description, except the multi-chamber, expansion chamber parts, which are not a binding part of the patent abstract, but a "possible" add-on to the base patent. It all depends on whether Confederate tried to patent it first - probably not. There were lots of fuel or oil in frame bikes before some guys thought to patent it..  | ||

I dont like the idea of a flex coupler in the exhaust that is going to be asked to flex as much as this would need to. It seems like a built in failure point. | ||
| Stirz007 |
Azx - my thoughts exactly when I first saw this a few years ago. Plus Inconel tends to work harden after it goes through a few heat cycles, making it more prone to fail. Remember, the folks who buy Confederates aren't necessarily thrashing them (Tom Cruise has a couple, I've been told). At $60K and up for a Confederate, you are looking at styling as much as function. JM | ||
| Froggy |
If it is indeed something that would wear out and fail, it would have a service interval similar to filters and fluids. I can't imagine a small piece of flex pipe costing a ton to replace, especially if it was engineered correctly for easy replacement similar to most of the service stuff on the rest of the Buells. | ||
| Hootowl |
The Buell patent was for the break-away steering head to protect the integrity of the tank, not making the frame a gas tank. | ||
| Reepicheep |
For the flex pipe, the oil fittings on the XB (and jet engines) flex all day long and do just fine. The flex fitting on my Saab exhaust is now pushing 130,000 miles (and one partial drowning, long story) and is still fine. The flex fitting on my old Saturn failed at about 130,000 miles, but in fairness the fitting was fine, the pipe it attached too had rotted away.

Exhausts with a rotating or flexible joint are nothing new. The technology already exists. Exhaust heated tipper bodies for cold climates have been around for many years. | ||
| Hughlysses |
Ha! Found it: http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=P TO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch- bool.html&r=1&f=G&l=50&co1=AND&d=PG01&s1=%22buell, +erik%22&OS=%22buell,+erik%22&RS=%22buell,+erik%22 The patent was filed on April 24, 2009 (well before the closure announcement) and the assignee is listed as "Buell Motorcycle Company". I hope it belongs to Erik outright. | ||

Wouldn't that increase unsprung weight? no more than holding oil in the swingarm.} | ||
| Rex |
I always wondered about the Confederate exhaust going thru the swing arm. Wouldn't that heat up the metal quite a bit? Wouldn't that heat up the axles and the bearings? Just wondering? Some exhausts get moisture and rust out, even the Buell mufflers. Wonder what this would do to the swing arm? REX |
