Hi,
Some of us report a Buzz in the bars and some of us say the M8 Softails are smooth as butter. Mine is an '18 Low Rider and it vibrates in the bars at anything over 2500rpm or thereabouts. I've tried Avon grips, poly bushings and experimented with an internal bar weight but nothing tames the buzz. The pegs and seat stay smooth. I've torqued everything I can think of. It is engine vibes not tires and wheels.
My question is this, has anyone noticed an increase or decrease with the addition of an aftermarket handlebar. Most aftermarket bars are heavier gage steel and I'm wondering if this would solve my problem or not. My stock low Rider bars are flimsy by comparison to most. I can deflect them by hand. I'm thinking they might be vibrating like a tuning fork. If I touch the riser it feels pretty smooth, but at the end of the bars it is really vibrating. Any thoughts?

 

Handlebar weights will tame those vibes. Do a google search, there are lots of choices.

 

My 114 Breakout vibrated through the bars between 2100-2500rpm. The frequency of the vibration sent my hands numb real quick. My Dyna shakes a lot more, but i don't get numb hands as quickly. For the record, i have carpal tunnel syndrome in both wrists, so i'm particularly sensitive to vibrations. One of the reasons i bought the M8 was because it vibrated less. Kinda funny that i'm better off with the Dyna.

 

Yeah, with the solid mounted Softails there is always going to be some buzzing at speed. Don't get that with the Dyna or Touring models, they are rubber mounted instead of the Solid mount that the Softys have.

 

I was initially bothered by the amount of handlebar buzz. I put on the Kuryakyn ISO grips with the Kuryakyn bar end weights attached, and it pretty much eliminated all vibration. I mean, there's still some when accelerating hard or at high RPMs, but at cruising speeds (2000-3000 RPM, constant speed) the vibration is just gone.

 

Yeah, I don't have bar weights on mine, but I do have the ISO Grips at this LINK. I don't even notice the buzz, even on 8 hour days.

 

Thanks for the replies.
Not all of the M8 Softails have the same bars. I think the amount of vibration isn't consistent across the range. Since I tried weights and grips, I may have to try some tracker bars made from .120 wall.

 

Changing bars is not a trivial task, but even so, I doubt it will resolve the problem unless the new bars are substantially heavier.

The Kuryakyn bar end weights work well because they float on the bar through the rubber inside the grips. The weight doesn't directly attach to the bar. The weight keeps the grip stable, and the vibration gets dissipated in the rubber inside the grip.

I have used this combo on a Street 750 (very buzzy, numb hands!) and on the Fat Bob's stock 1.50" bar, and on the Fat Bob with a replacement 1.25" bar. My experience is that they work very well in taming vibration.

 

my lowrider had a heck of a vibration when stock. I added the ISO grips with the end weights and it went away. I added 4 1/2" angled risers and the vibe is back. only on the left side though....

 

Interestingly, mine too is mostly buzz on the left hand side.
