I installed the T-Rex crash bars on my 2009 XB12XT. I am including some pictures that better depict the attachments points for everyone. The chin spoiler was not in the way on the XT. This bar bolts to the engine, and the frame, so their is a noticeable increase in vibration up to 4000rpm or so.      (Message edited by joescrambled on January 25, 2016) | ||

That does seem like a compromise, mounting to both the engine and frame. I wonder if it will get stress cracks, after a period of time? | ||

i hope you never have to test it | ||

The front isolator mounting bolts have now been compromised due to insufficient insertion depth. Also, transmitting an impact's force directly to aluminum castings is a real engine destroyer. I hope you prove me wrong but that's what I'm seeing in those pictures. | ||

T-Rex provides longer isolator mounting bolts that are black grade 8. so the insertion depth is not compromised. Bolting it to a cylinder head, you are correct. A hard crash would destroy the head. But to be honest, the most offroading this bike will see is level b maintenance roads, and gravel roads leading to local wineries. Even with the scrambler with TKC-80's, I dont offroad nearly as much as I thought I would. These are more for low speed boo boos, a place to put on a pair of highway pegs, a coffee cup holder, and looks. | ||

A head is cheaper and easier to replace than a frame. | ||

Froggy, I disagree. I could patch a frame in a walmart parking lot. The head would be an intense bit of wrenching. I have noticed that 80% of the modifications that I do to Buells. I wind up reversing. The 20% that are keepers; Race ECM, SHINDENGEN FH020AA REGULATOR. Dream money; Spares on a shelf. | ||

Get a big plastic cup and a bungee cord around the triple tail. ¡Viola! Cup holder! Did that for over a year. (Message edited by Phelan on January 27, 2016) | ||

Ourdee, if you crashed hard enough that this broke the head, you would have caused extensive damage to the frame without a guard. Some bondo and paint is not properly fixing the most important structural piece of the motorcycle. A replacement numbers matching frame is well over a grand plus time/labor to replace it. Replacing the head is a lot cheaper and less involved. | ||

When I endo'd into the Corolla, I broke the rear head to heim joint to frame mount. And that was a stock setup, without any crash bars. The frame, as far as I have been able to discern, is fine. | ||

Froggy, I don't use bondo. Epoxy, yes. Bondo , no. The scenario I contemplate is 750+ miles from home. What can I do to get home on the bike. Bondo and paint is like putting make-up on a broken arm. I'll build it a cast, or epoxy in a plate. | ||

My crash bar broke on the 305th mile of a very boring trip on i-80. It sheared in 2 places, and i ended up taking it off before it fell off on the side of I-80. I will not be replacing it until a better design is out. | ||

Hey, Joe-- Any chance of a photo or two of the broken piece, with, maybe, a post-mortem on how and why it broke? I put a set of T-Rex bars on mine this winter, too. Thanks. | ||
| Natexlh1000 |
It broke just being on the bike!? WTF? | ||
| Joescrambled |
  as you can see, it broke near the frame, and near the engine mount. was not at any weld joint, and i dont care what the ad says, this is not 7/8 tubing, because things like my cup holder on my 7/8 handlebar are too big for this 7/8 tube. maybe its a different 7/8 inch measurement. Spanish 7/8 maybe? | ||
| Natexlh1000 |
Perhaps 7/8 of a cm? 8.8mm? Carbon embrittlement perhaps? Suppose they used a torch to weld them? | ||

I have the same crash bar... it was on the bike when I bought it and has broken in several places. It seems like the solution is additional gussets. You can see pics of my bike here: http://www.badweatherbikers.com/buell/messages/142 838/779814.html?1457096754 I am planning on taking it to a welder friend of mine and gusseting the rest of the corners and reinforcing it with some additional tubing sleeved over a couple of places. I plan on using my bike pretty hard off road so I need this thing to work.  Cheers, Claude |
