SWM Crashbar Vibe Fix

Lose the U-bolts...

No, seriously. As most of you know (that have SWM crashbars), they can be vibration inducing on some Vs. I had taken to loosening the U-bolts as much as possible and added rubber between them and the frame. I felt that I had reduced the problem to a tolerable level. But it still bothered me (after 2 years) that if I slightly over-tightened the U-bolts more than finger-tight the vibes came through.

It occurred to me that the bolts were now so loose that they did little structural good, so I decided to remove them entirely. I cut a couple of rubber pads (from an old mouse pad) and used some 8mm flat head bolts to bolt the pads between the bars and the frame.

There is now a noticeable difference in the vibration level in the V with this mod. It just feels smoother.

You might want to try it. Just take the U-bolts off and go for a ride. I think you'll find a whole different feel to your V. While riding, reach down and feel the vibes in the bar; then feel the lack of vibes in the frame.

Good findings.

I would think that putting back the U bolt but just hand tightened the bolts would be better so that it would still hold the bars in an event of a drop. It would take some of the stresses from the other 2 bolt joints it limits any severe displacements of the bar.

Your motor has rubber mounts, doesn´t it? (2010 and on..)
So it seems like a logical mod. Given the fact that the bar mountings are fixed in or near the motor(bolts?) itself. Then you "bypass" the rubber mountings and get the vibration to the frame via the crash bars..

His is a 2008... 2010+ models have rubber in the upper rear motor mounts only.

Ok. Old V - no rubber mounts. My explanation failed But still - if you transfer the vibes from a motor mount where the bar is fitted, and lead them higher up to the frame and closer to your a-s they might tickle you more, compared to if you did not have a crashbar

Having SWs on my '09 (and associated vibes...!), I think I would NOT remove the U-bolts that are anchoring it, so that it remains ... a crash bar.

Agreed. The U bolt need to be tight to prevent any movement in a crash.
Try putting some washers with rubber washers. It will spread the load and absorb some of the annoying vibs.

go the other way

I went the other way to fix mine...I tossed the plastic piece that came with the kit and cranked the u bolt tight , now it solid and doesn't move or vibe......I also used the torque values from the service manual on the engine bolts and not the spec provided by SWM...

SWM crash bars vibes

Have an 08 V. With my SWM bars on...total and intolerable frame vibration. Removed crash bars...vibrations way back down to normal tolerable levels. From my perspective it has a lot to do with the extended rear mount bolt that comes with the crash bars. You're taking a factory bolt that's 4-5 inches long and replacing it with a 12" bolt. As we know for grade 9 physics vibration waves grow over linear travel...the Tsunami effect. The u bolts then complete the circuit by transferring those amplified vibrations directly to the main frame. Theres also an extended bolt for the front left mount too which I'm sure is adding to the effect. I would assume this is more an issue with older V's with no rubber motor mounts. Hope SW Motech or twisted throttle is reading this thread and offer a fix. I paid a lot of money for these crash bars (and I liked have highway pegs) just so they can sit on a shelf in my garage.

I just bought a set of the Hepco Becker crash bars. I don't notice any extra vibes from the HB's. They have a very nice finish too, top quality stuff.

I got them from here: http://capitalcycle.com/

dang weljo.

i have swm on my other ride, they were the stoutest of all that i check out and had the best coverage.

the swm's imo are heavier duty and have better coverage than the HB's but it's not like i plan to dump this one much. the last couple were "true" dual sports, by someone's definition.....however this bike is SO MUCH BETTER than my 800gs i can't begin to get over it...SO much BETTER.

I have H-Bs on my '08, so when I got the '09 I TRIED to order another set, but couldn't in a reasonable time-frame, so I ordered S-Ws for it and installed them. Like weljo, I've crash-tested my H-Bs, and 2 small pieces of electricians' tape covered the 'damage'. I've never noticed any more vibes than stock on the H-Bs.

My '09, however, has SERIOUS vibes since the S-W install. I put a set of Aprilia mirrors on it, and now I can see what's behind me...!

The u-bolts serve for structural integrity in the case of a crash. The force would drive the mount up and over the frame member.

I did the same mod, edp high density rubber instead of the plastic crap they supplied (which was squashed flat), and just snugged the nuts up tight enough so there wasn't play. They are lock nuts so they won't vibrate loose.

This eliminated about 75% of the vibes I had from them. Right at 4800 in a very narrow rpm band there is some harshness from vibes. But it's much smoother overall and much less noticeable. The best thing I ever did for vibes was balance the tires.

The crash bar fits very snug against the frame. I wonder what shimming it out would do so it wasn't so tight and then run the u-bolts in there snug but not tight. I may try that one day if I get really bored, or go and trade the thing off.

That's interesting you'd say that. One of my best riding buddies that also has a TE630, came from an 8gs. He said he liked it but hated it at the same time.

I keep thinking Tiger 800 or Super Tenere for more 2-up. I just gotta go ride them I guess. But I'll be keeping the TE, it's a keeper.

The versys sure is fun to ride though, and very easy to ride, very forgiving. I like that it passes cars like stationary objects.

Please do tell us more.

so looks like HB's may be the way to go for me after a TON of reading last night.

where do you all say the best place to buy?
