SW Motech Crash Bars

Last week I had the SW Motech Crash bars installed from Twisted Throttle.
The quality is good, they look good, seem like they would protect the bike well and straight forward to install. They are installed in three places: A long bolt through the back of the engine, near the gear shift; a u-clamp on the engine frame and a stud at the front of the engine block. Very secure.
The problem is that I now feel vibration which resonates at 4000rpm. I can feel it in the footpegs and an audible buzz.
I think this vibration is being transferred from the engine to the frame via the crash bars. Anyone else got any comments or has same experience?

I had the same problem. Just a little buzz before the crash bars, tons now and I can feel the vibration in the fairings. The other day I put weather stripping around the gauges and that helped some, but not enough. Not sure what to try next.

I had some extra vibration when I put on my HB bar.
Retorqued it slightly less with DIY thin hard rubber mountings to absorb the vibration between the frame and bar.

Good Luck.

What kind of rubber would be good to make mounts? And where could I get some? Thanks!

Hey stlee29, I loosened the nuts on the u-clamp and most of the vibes have gone, so I didn't even need the rubber. Thanx for the idea.
Still have a wee fairing buzz at 4200rpm though, but I will find that too.

I just was doing a search on SW Motech crash bar vibrations and it brought me to this forum. I own a Triumph Tiger 1050 and recently had the Motechs put on my bike by Twisted Throttle at their open house. I get a bad "buzz" above 5000 rpms. I re torqued the bars but this helped little. I emailed TT but they deny this happens. I of course went through anything else that may cause this but everything is within limits. At my forum tiger1050.com, other members also have this problem. I see at the KLR and Vstrom sites the bars do the same thing to those models. PLEASE do not let Twisted Throttle get away with this. Inform them of your displeasure and demand they refund your money!

Received the SWMotech engine today and in view of your vibration and the same problem others mentioned I am considering returning them to Tthrottle.Is the vibration bad enough to be a deal breaker or is it tolerable.Thanks for your help.

It's definitely tolerable. The bars work well for what they're designed to do (protect the engine cases). Avoiding a little extra vibe through the pegs isn't worth the damage you risk by not mounting them.

Maybe I drink too much..But I could have sworn the V engine mounts directly to the frame...My V vibed the same at 4500 without the H&B's and with the H&B's...And by vibe, I mean just a tad, not a knock your foot off the peg Harley vibe...
You can trust me when I tell you that the H&B's I put on my V paid for themselves "at least once"...

If I new what I was doing, I wouldn't still be working

Mine did not cause any vibrations at all. Did you guys put the plastic/rubber covers on the frame tubes under the U clamps?

Any body out there with the Happy Trails guards? I'm thinking of getting these and was curious if they had experienced the same vib. issue as the Sw.

I still wonder if the guys with vib issues installed the included plastic frame spacer under the U clamp. I did and don't have any vibs at all.

I had minimal vibe after install of the Motech crash guards. It is completely tolerable and well worth having the added protection. Most of my vibration came after I installed a handle bar brace. I had to replace the grips, put rubber dampeners on my mirrors, re-install the bar ends, and I still have a audible buzz coming from my shift lever adjustment knob. Still thinking about how to make that stop...

It's not just the SW stuff.

See the Hepco Becker thread on vibration issues.
