If you want to remove your subframe and dont want to buy the $160 BMW exhaust hanger, I made a few of these. $25 shipped. Ready to paint or chrome. Uses the bolts from the subframe.

 

[gerry]

Would you ship one for me to Switzerland ( or Germany )

 

[Bonkorama]

Dave, Sent you a personal message. Want one. Sold.

 

[dave]

Would you ship one for me to Switzerland ( or Germany )

I would. Let me find out the extra cost. Please PM me your address.

 

[dave]

here is the original blank one that shows its position. There is a unused hole between the footpeg bolts. One of the bolts from the unused subframe can be used to secure it there. The other end goes to the muffler hangar.

 

[gerry]

I would. Let me find out the extra cost. Please PM me your address.

Does somebody else from Europe want's one ? Perhaps we can make a European order.... Customs fee will be the same (19%), but shipping costs could be devided....
I would dispatch inside Europe (EU)

 

[Mr. Bones]

Customs fee is far less than 19% ( what you mean is tax, Gerry ).

There will be no customs fee as long as the goods are sent from one private individual to another and if the value is below € 45,- ( around $ 62,00 ) per shipment.

[gerry]

yes, of course customs fee depends on the value.

Not trying to p*** on your parade

Fair play to you Dave on your new money spinner ,but I have concerns to the styling for your actual support of the exhaust can to frame and can as your stay only has two bolt holes for fixings one frame one can and the frame end needs two fixing points to give full support otherwise it could just drop even if tightened to extremes .
The BMW hanger is a triangle design to offer better stress fixings from the removed pillion pegs fixing point to eliminate flex ,if you made your frame end connection with another fixing point (2) you will be onto a winner IMHO
Again I'm not knocking you

Over 290 miles with this set up. No issues. The mount acts more like a stay than a hanger. There is relatively little weight actually "hanging"from it . I understand your logic though.

I agree with Bose's opinion. Sooner or later your mount will brake.

I agree with Bose's opinion. Sooner or later your mount will brake.

If the collector was not mounted to the frame on its own mount I would agree with you. But since the bulk of the exhaust is carried by that mount, I would have to disagree. Pull the bolt from the muffler mount and you can see and feel for yourself what I'am talking about. But to each his own.

 

[Bonkorama]

Sounds like its function is more of a stabilizer than load bearing.

 

[Archon]

The rest of the exhaust supports most of the weight. I think this bracket is fine.

 

[Lost Rider]

Internet engineers, got to love it, especially since I don't believe either of them actually have a 9T in an obviously well tooled shop to work on. Let alone the bracket being offered up to forum members for a price well below what they could be sold for, or the actual cost to make up with all the time and tools needed.

I will be using one of these asap, having it break or damaging my bike is the least of my concerns. I checked out a guys 9T a few days ago, looking at how I'm going to make something similar to support the exhaust since I can't get a BMW bracket, this not only saves me time, but is obviously much more refined than I would have made with a Dremel.

Thanks Dave.

 

[Bonkorama]

+1 what Lost said. I'm in as well.
And I think Dave did a rockin good job on it.

 

[M&M]

@ Lost Rider, I know perfectly what forces are exercised on the fixing point of the exhaust (I changed my exhaust myself) and i know how strong the OEM fixing point is since i had a car destroying my exhaust from behind.
There is no difference between the R1200R and the nine-T in that matter.



There's not only the weight of the exhaust, but much more the vibrations and the side movements that are not contained.

Nevertheless, I like what Dave made. But since he seems to be very talented, he's probably capable to improve his concept.

+1 M&M said. You need a triangle & rigidity, but you don't have to believe one of the internet engineers

2nd that, great work Dave it does look very nice. There is a good deal of stress on the exhaust if it isn't supported correctly though. I am not saying it will break, because honestly I don't know, but it's enough of a possibility that I would not run something like this on my bike. With this setup, the heating and cooling of the metal as well as the vibration and shock from bumps will likely cause more metal fatigue over time than usual. The bracket itself could break, but with only 2 mounting points it probably won't. Instead in will slowly pivot downward putting stress on the weld just before the Y splitter of the muffler. The weld itself won't crack if it's a good one, but the pipe will, right at the edge of the weld. (A good weld is generally stronger than the base metal)


On a car or truck the exhaust is mounted using rubber hangers. This allows a relatively long length of pipe a moderate amount of movement. The pipe flexes as it bounces around, and shares these stresses over the entire length. If an exhaust hanger were to be removed from the system it would allow the system to move too much and break at the most rigid point.

On a motorcycle the exhaust system is much shorter and more rigid. To allow it to move causes a significant amount of stress over a small area. This is why they are not mounted with rubber hangers.


Like Tracteur said, triangle! I'd rather not have to pay for a new pipe.

Will it break? I don't know! But if it does you'll know why!

There's another 2 cents from an internet engineer ( nationally certified welding inspector with a degree in manufacturing) who hasn't seen the NineT in person yet.
